Modules

The COMPASS software consists of three main modules integrated by supporting features and an underlying data structure.

Survey

The Survey module calculates a wellbore’s trajectory. The COMPASS software considers a survey to be a set of observations made with a single survey tool in the same tool run. Data can be entered in a spreadsheet or imported and processed using industry-standard

calculation methods. The resulting survey files can be edited, printed, or analyzed. Surveys may be spliced together to form a definitive best path by using a tool interval editor. Special provisions are made for Inertial- and Inclination-only surveys. The Survey module provides an advanced “Project Ahead” from survey station to target, formation, or well plan. Two methods enable you to assess survey data for incorrectly entered survey data or bad readings from the survey tool. Input Validation isolates bad survey data as soon as it is entered. Varying Curvature isolates incorrect survey station data by highlighting its inconsistency. Survey analysis graphs produce comparison plots of survey and plan data for a number of different variables.

The COMPASS survey data can be referenced to any number of user-defined datums and can include a number of canned or custom formatted report layouts that you can send to an ASCII file. You can also export survey data to a raw survey file, or output it to a number of canned or custom export file formats.

(24)

After you enter data, you can do the following:

• perform point interpolations for any number of measured or true vertical depths, inclinations, or azimuths

• use the Project Ahead tool to compare the wellpath’s current trajectory against a proposed target or plan

• perform free projections to a proposed MD or TVD by using an entered Build and Turn rate, dogleg, and toolface, or by

constructing a trend that uses a number of existing survey observations.

Planning

Use the Plan Editor to design the shape of proposed wellbores. The Planning environment has an interactive editing worksheet that allows you to build up the well trajectory in sections. Many different plan sections are available for each section, and they can be based on two- or three-dimensional Slant or S-Shaped profiles, or three-dimensional dogleg/toolface, or build/turn curves. Alternatively, the plan can be imported or entered directly into the spreadsheet line-by-line. At each stage of well planning, you can see the wellbore graphics dynamically update as changes are made. You can revisit, insert, or delete any section of a plan, and the whole plan will be recomputed.

The Wellbore Optimiser integrates torque drag analysis into the planning module. It determines the best combination of trajectory design parameters that lead to the minimum cost, anticollision, or torque and drag solution. Planned designs that are undrillable because they will cause colliding with other wellbores or exceed the drill strings tension, torque, buckling, side force, or fatigue limits are indicated.

The following different plan methods are supported:

• Slant Well and S-Well designs are available to plan a well within a vertical section.

• In 3D, you can construct plans that use Build and Turn curves for rotary-drilled sections or Dogleg/Toolface curves for steering tool-drilled sections.

(25)

COMPASS™ Software Release 5000.1.7 Training Manual 1-5 Chapter 1: Introduction • You can also use additional tools such as Optimum Align, which

enables steering to be minimized to certain user-selected parts of the well; Thread Targets, which automatically constructs a plan through two or more targets that use various plan types; and the Landing Calculator, which enables a plan to intersect a target plane along a given azimuth.

• For long hold sections, a plan can be corrected for anticipated Walk rates through certain formations.

Anticollision

Anticollision can be used to check the separation of surveyed and planned wellbores from offset wells. Anticollision provides spider plots, ladder plots, traveling cylinder, and printouts of well proximity scans. Any anticollision scans can be run interactively with planning,

surveying, or projecting ahead. All anticollision calculations are integrated with wellbore uncertainties that are shown on graphs or reported as separation ratios. Warnings may be configured to alert you when the wellbores converge within a minimum ratio or distance that is specified by company policy.

The following plots are available:

• Travelling Cylinder View – wellpath separation referenced from either the high side of the well or the high side plus current well azimuth

• Ladder View – MD versus wellpath separation

• Separation Factor View – MD versus separation factor • 3D Proximity View – 3D presentation of all wells included in

the scan

• Spider Plot – Plan view of all wellpaths included in the scan • Error Ellipse report – description of the geometry of the

Who Should Use the COMPASS

™

Software

The COMPASS software is designed for engineers with different responsibilities and for different types of organizations, such as oil companies, directional/survey contractors, and engineering consultants. Different users use the COMPASS software in different ways and work with different modules according to their job requirements.

An engineer can use this software to track a well through the following stages:

• the initial data-gathering stage, determining required geological targets, surface drilling locations, and planning constraints • the various phases of directional well design, including collision

avoidance, target analysis, operational stages of recording surveys, checking for anticollision risks, doing look-aheads, and performing survey quality assessments

• the compilation of a final definitive survey

Within an oil company, a Well Planner plans a well to intersect one or more targets provided by their Geoscience department. Targets are analyzed and sized in conjunction with the design of the survey

program. The plan can be 2D or 3D and may require the use of rotary or steerable bottomhole assemblies for it to be drilled. The plan is

communicated to and agreed upon by all concerned parties. While drilling, the Rigsite Company Representative uses the

COMPASS software to enter and collate survey data, report the wellpath trajectory back to town, and perform quality control checks on the data to ensure the survey contractor obtains and records data correctly. In town, the Operations Engineer in the Drilling Office receives the survey data, adds it to their COMPASS database, and shares it with other parts of their organization or with partners.

Both engineers may perform anticollision scans down the active well to assess the collision risk. Also, they may compare the actual wellpath trajectory with the directional well plan to ensure that the well is on track. If the well veers away from the plan, they can do Back-On-Track calculations to steer the wellpath back to its planned trajectory.

When the well is completed, the final definitive survey is composed, locked, and made available for use with anticollision scanning or

(27)

COMPASS™ Software Release 5000.1.7 Training Manual 1-7 Chapter 1: Introduction A Directional Contractor may use the COMPASS software to plan a well on behalf of an oil company. At the rigsite, contract Surveyors and Directional Drillers use the COMPASS software to enter survey data as it is received at the surface or read on the drill floor, and a comparison is made with the planned trajectory. The data is checked for errors and then reported to the oil company representative in the form of reports, graphs, or wallplots.

The contractor can also provide the data electronically on a disk or send it across a network. If their client also uses the COMPASS software, they can send a transfer file to the Company Representative or Drilling Office.

Directional Well Planners specialize in designing and assessing wellpaths for a number of conditions. In addition to planning wells through various targets and assessing the plan for a collision risk, they use geologic targets provided by the Geoscience group to construct drilling targets. This process is achieved using survey tool error models applied down the planned wellpath to reduce the size of the target surface. This modeling enables the planner to design a cost-effective survey program that is applied to the given geological target sizes. A Survey Focal Point is responsible for maintaining an accessible quality-checked survey database for an oil company. They can also be involved in analyzing positional uncertainty error models associated with different types of survey tools. Based on the accuracy and

reliability of different tools, they can recommend the use of certain tools to the Well Planning group.

Licensing and Installation

The following three types of installations are available for EDM applications:

• Local (Standalone) Installation: This type of installation is appropriate for engineers that need to install EDM locally on a single computer to be used by one person. This installation copies the product software, database, and all required support files to the designated directory on the computer’s local hard drive. For more information, see the EDM Common Installation guide.

(28)

• Server (Network Server) Installation: This installation should be used when the EDM applications will be installed centrally on a server to be shared by a number of users. This installation copies the product software, database, and all required support files to the designated shared directory on the network server. These files must be accessible to the network client computers. For more

information, see the EDM Common Installation guide.

• Client (Network Client) Installation: This installation is used when EDM applications will be run from the network. The client installation copies only the required system files to the local computer’s hard drive, then creates shortcuts to the shared

application executable files located in a designated directory on the network server. For more information, see the EDM Common

Installation guide.

Licensing

FLEXlm is a licensing method common to all Landmark products. It provides a single licensing system that integrates across PC and network environments. FLEXlm Licensing files and FLEXlm Bitlocks are supported for Landmark Drilling and Well Services applications. For more information, see the EDM Common Installation guide.

The Engineer’s Data Model

(EDM

™

) Database

Overview

Many of the Landmark® drilling applications use a common database and data structure—the Engineer’s Data Model (EDM™) database—to support the different levels of data that are required to use the

Landmark drilling and production software.

This database provides a significant advantage while using the software because of improved integration between drilling software products. Currently, the following software products use the common database and data structure: COMPASS™, CasingSeat™, StressCheck™, WELLPLAN™, WELLCAT™, OpenWells®, PROFILE™, and Well Cost™.

In this chapter, you will be introduced to: ❏ logging in to the database

❏ data structure ❏ common data ❏ data locking

❏ importing and exporting data

COMPASS™ Software Release 5000.1.7 Training Manual 2-3 Chapter 2: The Engineer’s Data Model (EDM™) Database

Describing the Data Structure

The EDM database has a hierarchical data structure to support the different levels of data that are required by different drilling suite applications. EDM uses the following hierarchical levels:

EDM™ Hierarchical Data Structure

Hierarchical Level

Description

Database Database is the highest level in the Well Explorer hierarchy. You can only work in one database at a time. For more information, see “Working at the Database Level” on page 3-7.

Company Company is the second-highest data level in the hierarchy. You can define several companies within the database you are using. Each company must have a unique name. If you work for an operator, you most likely have only one company. If you work for a service company, you may have several companies. For more information, see “Working at the Company Level” on page 3-14. Project Project is the data level directly beneath company. Each project

within a company must have a unique name. A project can be thought of as a field or as a group of sites. A project has one system datum (mean sea level, lowest astronomical tide, and so on) that is used to define 0 TVD for the project. Within the project, wellbores can be referenced to the project level system datum or to additional datums specified at the well level. For more information, see “Using Datums in EDM™” on page 2-21 or “Working at the Project Level” on page 3-35.

Company Project Site Well Design Case Wellbore Company Database

Hierarchical database structure of the EDM database.

(32)

Site Site is the data level directly beneath the Project level. Each site within a project must have a unique name. A site is a collection of one or more wells that are all referenced from a local coordinated system centered on the site location. A site can be a single land well, an offshore subsea well, a group of wells drilled from an onshore pad, or a group of wells drilled from an offshore platform. For more information, see “Working at the Site Level” on page 3-45.

Well Well is the data level directly beneath the Site level. Each well within a site must have a unique name. A well is simply a surface location. A well can have more than one wellbore associated with it. For example, the original wellbore may have one or more sidetracks tied on to it at different kick-off depths. For more information, see “Working at the Well Level” on page 3-56. Wellbore Wellbore is the data level directly beneath the Well level. Each

wellbore within a well must have a unique name. A wellbore is a compilation of one or more sections originating at the surface and continuing to a depth. A wellbore can be the original well drilled from the surface or a sidetrack drilled from a parent wellbore. If a well has an original hole and two sidetracks, the well has three wellbores. For more information, see “Working at the Wellbore Level” on page 3-64.

Design Design is the data level directly beneath the Wellbore level. Each design within a wellbore must have a unique name. A design can be thought of as a design phase. Associated with each design are a pore pressure group, a fracture pressure group, a temperature gradient, and a survey. A design may have several cases associated with it, but each case will use the same pore pressure group, fracture pressure group, temperature gradient, and survey. A design can be categorized as prototype, planned, or actual. You may have several different versions of prototype designs. For example, assume the geologist wants to analyze two different formation fracture gradients. This could easily be accomplished by having two prototype designs that are identical except for the fracture gradient group. The StressCheck and COMPASS applications routinely use designs. For more information, see “Working at the Design Level” on page 3-66.

EDM™ Hierarchical Data Structure

Associated Components

This section discusses several additional data components that are associated with designs or cases.

Associated with Designs

Wellpaths

A wellpath is a series of survey tool readings that have been observed in the same wellbore and increase with measured depth. All cases within the same design use the same wellpath.

Pore Pressure Groups

A Pore Pressure group is a set of pore pressures that define the pore pressure regime over a depth range from surface to some vertical depth. All cases within the same design use the same pore pressure.

Fracture Gradient Groups

A Fracture Gradient group is a set of fracture pressures that define the fracture gradient regime over a depth range from surface to some vertical depth. All cases within the same design use the same fracture gradient.

Geothermal Gradient Groups

A Geothermal Gradient group is a set of undisturbed earth temperatures that define the temperatures over a depth range from the surface to some vertical depth. All cases within the same design use the same

geothermal gradient. Associated with Cases

Hole Section Groups

A Hole Section group defines the wellbore as the workstring would see it. For example, a hole section may contain a riser, a casing section, and an open hole section. A hole section can also have a tubing section or a drill pipe section depending on the situation. Multiple cases may use the same hole section.

(34)

Assemblies

An Assembly defines the workstring. There are several types of workstrings, including coiled tubing, casing, drillstrings, liners, and tubing strings. Multiple cases may use the same assembly.

Fluids

A Fluid defines a drilling, cementing, or spacer fluid. A Fluid is linked to a case and a case can have more than one fluid linked to it. One fluid can be linked to multiple cases.

Copying and Pasting Associated Items

All of these associated items, with the exception of fluids, are

automatically created and associated (linked) by Well Explorer to the design or case.

All of these items are visible in Well Explorer so that you can copy and paste them by using the right-click menu. For example, when you copy a wellpath and paste it into a different design, the wellpath that currently exists for the target design is deleted. Well Explorer replaces the old wellpath with the copy of the new one.

Rules for Associating Components

The rules for associating components are listed below.

For Definitive Surveys, Pore Pressure Groups, Fracture Gradient Groups, Geothermal Gradient Groups, Assemblies, and Hole Sections: • Each component can only be associated with one design or case. • When one component is copied and pasted, an actual copy is made. • When one component is pasted, the component it replaces will be

deleted (unless it is locked).

• If the destination for the paste is locked (Design or Case) or the item to be replaced is locked, a message appears and the paste is not completed.

(35)

COMPASS™ Software Release 5000.1.7 Training Manual 2-7 Chapter 2: The Engineer’s Data Model (EDM™) Database For Fluids:

• When a fluid is copied and pasted, an actual copy is made. • When a fluid is pasted, the one it replaces will not be deleted. • Fluids can only be deleted by using the Fluid Editor in the

WELLPLAN software.

• If the destination case is locked or the fluid to be replaced is locked, a message appears and the paste is not completed.

(36)

Common Data

Common data stored in the EDM database and available for use by all Engineer’s Desktop™ (EDT™) applications in database mode include: • unit system • pipe catalog • connections catalog • pore pressure • fracture gradient • temperature gradient • surveys

• all fields in Well Explorer Properties dialog boxes • general data, such as well name, well depth, and vertical

section information

Note

Several additional fields are common to two or more applications, but not to all. Drilling applications may share other data not listed.

(37)

Data Locking

You can prevent other people from making changes to data by locking data at various levels and setting passwords. When locked, the data item can only be opened in read-only mode; to keep changes, use Save As or Export.

How Locking Works

You can lock Company properties only, or you can lock properties for all levels below Company (Project, Site, Well, Wellbore, Design, and Case). Passwords can be set to prevent unlocking.

By default, no passwords are set, and the locked check box on all Properties dialog boxes can be toggled on and off at will with no security to prevent users from doing something they should not do.

In the Well Explorer, if a data item is locked, a small blue key appears in the corner of its icon. When you open a locked data item, you will see the following message:

This Design is locked and therefore Read-Only. Changes to this Design will not be saved to the database. To keep your changes, use the Save As or Export options.

Locking Company Properties

For company data you want protected, two buttons are in the Company Properties dialog box, Company Level and Locked Data. There is also a check box named “Company is locked.”

When you click the Company Level button, you are prompted to set a password to protect Company properties (and only the Company properties). This password will then be required if a user wants to unlock company properties and make changes.

After the password is set, select the Company is locked check box to lock the Company properties and prevent unauthorized changes to the data.

(38)

Locking Levels Below Company

When you click the Locked Data button on the Company Properties dialog box, you are prompted to set a password. This password will then be required if a user wants to unlock any level below the Company (Projects, Sites, Wells, Wellbores, Designs, and Cases).

All levels are locked individually—you can lock a well, but levels below it are not locked.

After the Locked Data password is set, you can lock properties for any data level below Company and prevent unauthorized changes to the data. Open the Properties dialog box for the data level you want to lock, and select the locked check box. (For example, to lock a wellbore, open the Wellbore Properties dialog box, and select to lock Wellbore.)

Locked Designs

When a design is locked, all associated items (Pore Pressure, Fracture Gradient, Geothermal Gradient, and Wellpath) are also locked.

(39)

Concurrent Use of Same Data By Multiple Users

EDM supports concurrency for multiple users on the same data set. The Simultaneous Activity Monitor (SAM) is the service used to regulate concurrent access to the EDM database. For in-depth information about SAM, see the EDM Administration Utility online help.

• By default, the SAM server is enabled and connected, and a green SAM icon appears in the status bar of your application. • If the SAM service is configured but not connected, the SAM icon

appears with a red X drawn through it. Consult your System Administrator.

• If the SAM service is not configured, the SAM icon does not appear in the status bar.

A good practice for any multi-user environment is to frequently press F5 to refresh the Well Explorer contents. Data updates (such as inserts, updates, and deletions) are not always automatically recognized in other EDM sessions and simultaneously running EDM applications.

How the Well Explorer Handles Concurrent Users

The Well Explorer and the Simultaneous Activity Monitor handle concurrency as follows: If a user has a design open in Read/Write mode, all other users can only open the design in Read-only mode. If no one has opened the Read/Write mode to the design, it may be accessed. The red SAM icon indicates that one or more users have this item open, and you are restricted to opening it in Read-only mode. You cannot save any changes to the database, but you can use Save As and rename the item.

The blue SAM icon indicates that one or more users have this item open, but you can still open it in Read/Write mode. You can save changes to the database.

These SAM icons appear on a design (in the COMPASS, WELLPLAN, StressCheck, and CasingSeat software) or a Well (in the OpenWells software) in the Well Explorer.

(40)

Chapter 2: The Engineer’s Data Model (EDM™) Database Same User on Same Computer

If the same user has a design open in one EDM application and then opens the same design in another EDM application on the same

machine, the blue SAM icon appears in the Well Explorer of the second application. This icon indicates that this user has the Design locked for use in Read/Write mode, and has it open in more than one application. However, because it is the same user, the user can save changes to the database made from either application.

Multiple Users, Different Computers

The first user to open a design or case in that well gets control, and the design or case is then locked for use in Read/Write mode. A red SAM icon indicates that more than one user is working with the Design or Case at the same time. However, only the first user can make changes; all other users open the design or case in Read-only mode. They can use Save As but not Save.

After the user who had access to the design or case in Read/Write mode closes the design or case, the red SAM icon disappears, and the design or case is available again. Read-only users have to close the design or case and reopen it to gain control.

(WELLPLAN software only) A user can save cases under a design that is currently locked for Read/Write use by someone else.

(41)

Reload Notification

If you are working with any of the data in the following list and a user with read/write privileges saves changes to the database, you will receive a notification indicating that another user has changed the data on which you are working.

You have the opportunity to use the changes saved to the database by the other user. You also have the opportunity to save the data with which you are working by using the Save As option. If you do not save your data with Save As, your changes will be overwritten by those made by the other user. (Your changes are only be overwritten if the other user saves his changes and you indicate that you want to use those changes when you receive notification.)

Items that are refreshed in this manner are: Design, Definitive Survey (Wellpath), Pore Pressure, Fracture Gradient, Geothermal Gradient, and Assemblies (Casing Scheme).

Note

If you have read privileges, any changes you make are only stored in memory and are not written to the database unless you save your data with Save As.

(42)

Simultaneous Activity Monitor (SAM)

EDM (the Engineer’s Data Model) supports full concurrency for multiple applications that are using the same data set through the Simultaneous Activity Monitor (SAM).

If the Simultaneous Activity Monitor has not been configured, the following message appears:

WELLPLAN could not connect to the SAM server. Please verify that the settings are configured correctly in the administration utility, and that the SAM server is running.

The Simultaneous Activity Monitor consists of a Messaging Server that notifies the user with an open application of all data currently open in other applications. The SAM icon appears in the application status bar as follows:

If a data item is open, an icon appears as follows:

• A red SAM icon indicates that one or more users on other PCs have this item open, and the current user is restricted to

Read-only access.

• A blue SAM icon indicates that one or more users on the current PC have this item open, but the current user still has full Read/Write access. A user must be careful when making changes to the data though this method enables data to automatically flow

SAM Icon Indications

Icon Message Description

A green SAM icon in the status bar indicates that the Messenger service is active.

A blue SAM icon with a red X on it indicates that the Messenger Service is not currently active.

No Icon No icon appearing in the application status bar indicates that the Simultaneous Activity Monitor has not been configured for the application.

The Wellbore Planner™ software is a well planning application

integrated into the Landmark Geological and Geophysical visualization Unix applications. Links with the COMPASS software enable Wellbore Planner users (geologists/geophysicists) to quickly construct well trajectories with COMPASS users (drillers), with both using their own data sets. This integration reduces planning time by eliminating the paper stage in which the details of the geologist’s targets are passed to the engineer in an iterative process.

The COMPASS software can import and export data directly to the Wellbore Planner software. This route also enables selective import of OpenWorks® software well trajectories. This type of tool enables planned trajectory or actual trajectory data to be easily shared between the engineering and geoscience disciplines.

Wellbore Planner™ Software Import

This feature allow you to import *.WBP files from the Wellbore Planner software. The file must be moved to the Windows® COMPASS computer by FTP link.

The Import rules are as follows:

• If you are moving the data to an existing Company, Field, or Site, open them before the import.

• If you do not want the import to interfere with existing data, open a new Company. To access the File Open dialog box, from the COMPASS main menu, select File > Import > Wellbore Planner. Select the file to import (*.WBP).

If you are importing to an existing site, a message box appears displaying the following:

COMPASS™ Software Release 5000.1.7 Training Manual 2-19 Chapter 2: The Engineer’s Data Model (EDM™) Database If you have already chosen a site, the following message appears:

Importing file xxxx.wbp to site yyyy, click OK to continue.

If the Map coordinates contained in the Wellbore Planner file disagree with the current site, or disagree within itself, the data is still imported, but you must check it, and the following message appears:

Well xxxx has strange starting coordinates

Wellbore Planner™ Software Export

This feature exports a file in the Wellbore Planner format for import to a geological application, such as the OpenVision™ software. The file must be moved from the COMPASS software for Windows PC via FTP. In the COMPASS software, open the Customer, Field, and Site of interest. Then, from the COMPASS main menu, select File > Export > Wellbore Planner. The COMPASS software then asks the name and destined location of the export file.

DIMS

™

Software for Windows

®

Survey Import

The DIMS™ software for Windows is the Landmark Drilling and Well Services Daily Drilling and Completions Reporting System (DIMS). Typically, the DIMS software is used at the rig site as part of a client’s daily drilling reporting procedure. Built-in links between the

COMPASS software and the DIMS software for Windows enables easy transfer of survey information from the DIMS software to the

COMPASS software to reduce survey data-entry duplication. To access the DIMS survey import tool, open a wellpath in the

COMPASS software to which you want to import surveys. The DIMS survey import also requires an ODBC data source that you use to access the DIMS for Windows database. A database connection is the PC’s mappings of how software applications should open a database. Both the COMPASS software and the DIMS software for Windows require defined ODBC connections before the applications run. Consult your systems administrator to build a DIMS ODBC data source if one is not available.

Chapter 2: The Engineer’s Data Model (EDM™) Database Well

Select a DIMS well from the pull-down list. The COMPASS software populates the SideTrack list box with the sidetracks for that well defined within the DIMS software.

Sidetrack

Select a DIMS sidetrack from which the COMPASS software will import surveys. Each unique survey tool within the DIMS software for the sidetrack is displayed in the Tool Mappings grid.

Tool Mappings

The DIMS survey tools must be mapped to equivalent COMPASS survey tools. This mapping is necessary because there is no connection between them, and the COMPASS software requires a correct tool mapping to calculate positional uncertainty. You must do this for all DIMS tools before starting the import. The COMPASS software remembers survey tool mappings for future use.

When mappings are complete, click the OK button. The COMPASS software imports the DIMS data, creating a separate survey for each one of the mappings.

Using Datums in EDM

™

Definition of Terms Associated With Datums

This section defines datum terms. They are grouped by the Properties dialog box in which they are found.

Project Properties

System Datum

The System Datum is set in the Project Properties/General dialog box and represents absolute zero. It is the surface depth datum from which all well depths are measured, and all well depths are stored in the database relative to this datum. Usually, the System Datum is mean sea level, mean ground level, or lowest astronomical tide, but it can also be the wellhead, rigfloor, RKB, and so on.

Elevation

The Elevation is set in the Project Properties/General dialog box, and represents the elevation above mean sea level. (If Mean Sea Level is selected as the System Datum, Elevation is grayed out.)

Well Properties

Depth Reference Datum

The Depth Reference Datum represents zero MD. It is sometimes known as the local datum, and it is measured as an elevation from the System Datum. You can define one or more Depth Reference Datums for a well in the Depth Reference tab (Well Properties dialog box). For each Depth Reference Datum, you must specify the elevation above or below the System Datum.

The selected default Depth Reference datum in the list box is the viewing datum in all applications (the viewing datum can be changed on the fly only in the OpenWells and COMPASS applications).
