General Section
The General section enables operations summary information to be entered.
When creating a new Cementing report, be sure to select the appropriate casing string as entered in the OpenWells Casing report. As well as linking the cement job to the casing string, it also results in a number of common data items being copied over from the Casing report.
Job Area
Use the dropdown arrow to make a selection for the Job Type field. The job type selected from this picklist defines the availability of certain data entry fields and panels in the General section of the Cementing report. For example, the Plug area is only available for plug job types.
Details Area
Use the Assembly field to specify the assembly that is to be cemented. A dropdown picklist is available for this field.
Enter all other necessary information in the relevant fields.
Pipe Movement Area
Enter all necessary information to record if the pipe was reciprocated and/or rotated during the cement job.
Plug Area
This area will only appear when 'Plug' is selected as the Job Type in the Job area of the General section. Use this section to enter information on the Plug Type. A checkbox can be activated to indicate that the plug was Drilled Out, then enter the Drilled Out Date in the corresponding field.
Note:
If Casing reports have not been created for this Well, only the Open Hole appears in the picklist. OpenWells populates this picklist by searching the database for the String Type entries in Casing report’s dated on or before the date of the Cementing report. If the Casing report is dated after the Cementing report, the Assembly Name for that Report will not appear in the picklist.
Squeeze Area
This area will only appear when 'Squeeze' is selected as the Job Type in the Job area of the General section.
Fluids Section
The Fluids spreadsheet is used to enter Fluid information for each fluid circulated in one or more of the Cement Stages defined within the report.
Cementing Fluids Area
This area contains a spreadsheet used to capture new fluids.
Click the button to add a row to the bottom of the spreadsheet. Add as many rows in the spreadsheet as are needed for each fluid used in the cementing job.
All information located in the Fluid Details area below the spreadsheet relates to the Fluid selected in the spreadsheet. Click on the Fluid Name cell to display information relating to that particular fluid in the Fluid Details area.
Fluid Details Area
The Fluid Details area is subdivided into the following sections:
Volume
Record details about the fluid volumes while pumping the selected fluid. Some fields displayed are specific to cement slurries. Leave these fields blank for other types of fluids.
Rheology
Both the Fluid Name and Fluid Type fields are automatically
populated from data entered in the spreadsheet above. Use this area to record fluid density, name, and type as well as other details about the rheology of the fluid. The data entered in this area is used to model how the fluid will flow; this includes the fluids elasticity, plasticity, viscosity.
Pumping
Record information including start dates for slurry pumping,
displacement, and mixing. This area is also used to record displacements and temperatures while pumping.
Slurry
Enter Cement Slurry information such as purpose, type, class, density, description, and excesses.
Tests
Use the spreadsheet located in this area to record details about tests performed on the slurry fluid. These details include information on compression strength, temperature and time as well as fluid loss and thickening information.
Additives
Use the spreadsheet located in this area to record details about additives in the fluids including additive name, type, and concentration.
Stages Section
The Stages section is used to define each cement stage and pumping schedule included for the stage. Single stage and multi-Stage cement jobs are supported. Each stage can have several slurries. Each stage and each slurry section contains different types of data depending on whether the stage is a foam job or not.
Click the button to add a row to the bottom of the spreadsheet. Add as many rows in the spreadsheet as are needed to capture each stage of the cementing job.
Once a stage is entered into the spreadsheet, record information in the following areas:
Stage Details Area
The Stage Details Area contains two subsections: Stage Information and Pumping Schedule.
More Stage Information
This area is used for recording stage summary information such as pumping rates, method flags, pressure, and other stage information. A series of checkboxes help describe the details of the stage.
Pumping Schedule
The pumping schedule is the sequence of fluids pumped during the stage including shutdown periods. Enter the initial information into the schedule spreadsheet with fluids listed in the order they were pumped. Enter additional information in the Schedule Details and Foam Details areas.
Plug Status Area
The Plug Status area is only available when the Job Type selected in the General Section is Plug. Add rows to the Plug Status spreadsheet to add information.
Tests Section
The Tests section is used to determine the top of cement depth and also record the results of different tests performed to determine the quality of the cement bond between the borehole wall and the pipe
Casing Test Area
A Casing Pressure test is performed to test the isolation provided by the cement after a primary cement job. Pressure tests may also be performed after remedial cementing to record if perforations have been effectively sealed.
Enter the Casing Test Pressure, Casing Test Duration in the fields provided.
If cement was found between the shoe and the float collar, activate the Cement Found checkbox.
Shoe Test Area
Formation Integrity tests or Leak Off tests are normally performed after the shoe has been drilled out before drilling starts on the next hole section. The LOT or FIT test is performed to determine the strength of the wellbore formation below the shoe which is normally the weakest point for the next hole section.
Liner Top Test Area
Enter the results from either a positive or negative pressure test.
Interpretation Survey Area
This area records the evaluation of the Cement top depth, how it was located and what method was used to determine it.
Enter the appropriate data for any test completed in the test's corresponding area.
