These integrated data sets and case histories will provide operators with the critical parameters to optimize their exploitation of these reservoirs and reduce finding and development costs. Core Laboratories is conducting a major industry study of the reservoir characteristics and fracture stimulation response of tight gas sands. This project provides member companies with a comprehensive database consisting of laboratory rock property measurements, well log and production information from contributed wells, and case histories of production response to fracture stimulation from numerous formations and basins throughout North America. From the pore system through the 3-D Frac design and post-frac evaluation this project relates reservoir facies, reservoir quality, petrophysical properties and geomechanical properties to stimulation methods and production performance in tight gas sands. Major objectives of the project include the following:.

Currently, numerous oil and gas companies. are directing their efforts toward the exploration and exploitation of tight gas sand reservoirs. These reservoirs have proved to be challenging in terms of reservoir characterization and optimizing fracture stimulation techniques. Many companies do not have key rock property data that are crucial for understanding these reservoirs and for designing optimal fracture stimulations. Many treatment options are available and operators are often left with very expensive “trial and error” field testing of various fracture stimulation techniques. No hydraulic fracture design can be optimized, or in many cases, successfully performed or pumped in the field without the rock property data. Therefore, in order to properly evaluate and exploit tight gas sands, appropriate types of rock property data need to be measured and integrated with log data, stimulation techniques, and production. • Geologically characterize tight gas reservoirs in terms of depositional facies, environment of deposition, and rock types • Characterize and systematically classify the rock types and factors controlling reservoir quality • Describe and characterize fractures • Provide laboratory measured petrophysical properties for log calibration and pay recognition criteria • Develop saturation and permeability models • Determine the rock-fluid compatibility, regained gas permeability, and “water block” susceptibility • Measure the key geomechanical properties required for 3-D Frac design • Facilitate calibration of open-hole geomechanical logs with static geomechanical laboratory data • Integrate core data with well logs, fracture stimulation techniques and production test results. 3.

This gas shale reservoir has proved to be challenging in terms of reservoir characterization, predicting producibility potential, estimating ultimate recovery, and optimizing fracture stimulation techniques. Many companies either do not have or have limited rock property data that is crucial for understanding these reservoirs. Therefore, in order to properly evaluate and explore the Marcellus Shale, appropriate types of rock property data need to be measured and integrated with log data, stimulation techniques and production test information.

Core Laboratories is conducting a multi-company, geo-engineering study of the Marcellus Shale. This project consists of the characterization and evaluation of numerous conventional cores, rotary sidewall cores, and drill cutting samples taken from multiple wells targeting the Marcellus Shale. Specifically, the Marcellus Shale will be analyzed for geological, petrophysical, geomechanical, geochemical, and production properties. The data is integrated with well logs, stimulation designs, and production test information. This large and searchable database will provide operators with valuable information not only on their own wells within the Marcellus Shale, but also on other operators’ wells.

Ordovician-aged, calcareous, black shale that extends across the Appalachian Plateau from New York and Quebec, Canada, south to Tennessee. It therefore, underlies the Marcellus and extends farther west providing another shale reservoir target in Ohio, New York, Pennsylvania and West Virginia. The Utica Shale produces oil in Ohio and gas in the deeper portions of the basin to the east. In the near term, most activity is expected to be in the liquids-rich portion of the play in Ohio and western Pennsylvania. The Utica Shale has very different reservoir properties than the Marcellus and should be challenging in terms of reservoir characterization, predicting producibility potential, estimating ultimate recovery, and optimizing fracture stimulation techniques. Many companies either do not have or have limited rock property data. that are crucial for understanding this reservoir. Therefore, in order to properly evaluate and explore this resource, appropriate types of rock property data need to be measured and integrated with log data, stimulation techniques, and production test information.

The primary objective of this project is to provide operators with measured geological, petrophysical, geomechanical, geochemical, and production properties of the Utica Shale in order to improve their formation evaluation and to optimize stimulation and production. Our work suggests that understanding the similarities and differences in these shales on a regional basis is the key to successful exploration and exploitation.

T. he south Arkansas-north Louisiana (Arkla) area has long been the site of active exploration for structural and structural-stratigraphic traps. As most known structures have been extensively drilled, the focus is now centered on oil and gas to be found in subtle, stratigraphically controlled traps in the Pettet, James, and Rodessa. Study members are provided with the only available exploration and producing oriented study of the Arkla area that; provides a practical database which can be utilized for local prospect generation and regional trend evaluation, relates lithofacies and diagenesis to reservoir development, developed the depositional models needed to discover and evaluate similar stratigraphic and structural-stratigraphic traps, and assess completion and production techniques for these Lower Cretaceous carbonates and sandstones.. The analytical techniques utilized to characterize and evaluate nineteen (19) conventionally cored wells in the Pettet, James, and Rodessa consisted of conventional core description with continuous core color photography and extensive thin section petrology (including “whole” thin section photomicroscopy). Scanning electron microscopy (including pore cast analysis), mercury injection capillary pressure, and X-ray diffraction were done on selected “reservoir rock type” samples. Porosity, air permeability, and grain density were measured for all core plugs geologically analyzed. Results from these detailed geological characterizations were correlated to logs in the cored wells. Numerous other wells were integrated into the study using existing logs and this information was then used as an aid to correlate between cored and uncored wells. Facies and isopach maps, cross sections, depositional models, etc. were constructed and formulated by utilizing the core-to-log and log-to-log correlations. The study contains individual well reports and a final report which synthesizes the data in terms of the geological and petrophysical implications for reservoir quality trends in the study area. • Nin eteen ( 19) con ven tion ally cor ed wells • Well logs f r om n on -cor ed sur r oun din g wells • Pettet, James an d R odessa For mation s.

This play is maturing with mixed results from the horizontal wells in tight sections and a general poor understanding of what makes a good well. Recent discussions with several operators in the trend indicate that many operators are having common problems in locating the “sweet spots” for production in the trend and in their formation evaluation and reservoir characterization. These technical issues that the project addresses include but are not limited to the following: • What is controlling production in the James Lime? Is it depositional facies, natural fractures, thin permeable “sweet zones”, or a combination?. histories provide operators with the critical parameters to optimize their exploitation of the Haynesville and Bossier Shale and reduce finding and development costs. Core Laboratories is conducting this multi-company, geo-engineering study of the Haynesville and Bossier Shale. This project consists of the characterization and evaluation of numerous conventional cores, rotary sidewall cores, and drill cutting samples taken from multiple wells targeting the Haynesville and Bossier Shale. Specifically, these prospective shale sections will be analyzed for geological, petrophysical, geomechanical, geochemical, and production properties. This data will be integrated with well logs, stimulation designs, and production test information. This large and searchable database will provide operators with valuable information not only on their own wells within these shale sections, but also on other operator’s wells. The project will be focused on evaluating numerous Haynesville and Bossier Shale wells in East Texas and Northern Louisiana. • On goin g pr oject with over 100 wells. • How can we differentiate good reservoirs and areas from the non-commercial areas? • What are pay recognition criteria from logs for the James Lime and how much gas is in place?

These problems can only be solved from the geological, petrophysical and completion/stimulation analysis and evaluation of wells with either conventional cores or rotary sidewall cores. The resultant data is used to calibrate open-hole logs in order to better predict rock types and petrophysical properties essential for formation evaluation and proper well completion and stimulation designs. The rock types and their measured petrophysical properties can also serve as analogs when evaluating new reservoirs in wildcats or field step outs.. 13.

The Woodbine of upper Cretaceous Age has. been one of the most prolific oil and gas targets in the East Texas Basin. Exploration for Woodbine production in east Texas has been intensive since the first discovery was made at Mexia in October of 1920. The majority of Woodbine exploration and production has been confined to an area north of the Angelina-Caldwell flexure and the Edwards reef trend. Production from the Woodbine interval in this area has been from depths of between 3,000 to 6,000 feet. Recent discoveries of Woodbine gas, however, south of the Angelina-Caldwell flexure have extended the area of exploration. The Woodbine in this area is encountered at depths of 10,000 to greater than 15,000 feet. For purposes of this study, these two areas are referred to as the shallow and deep Woodbine of East Texas. The Late Cretaceous continental shelf and the beginning of the continental slope in east Texas are marked by the Angelina-Caldwell flexure and Edwards reef trend. The shallow Woodbine, therefore, represents deposition north of the shelf edge and the deep Woodbine represents deposition south of the shelf edge. This regional geologic study encompasses both areas of Woodbine deposition. Exploring for Woodbine production within the East Texas Basin is complex. Depositionally, the formation is complex. The sand bodies that form reservoirs are erratically distributed in the section and represent various environments from fluvial to marine. No single, simple, depositional model can be used for exploring for Woodbine traps. A regional study of the depositional environment for Woodbine clastics within the East Texas Basin provides valuable information to the petroleum explorationists.. • Select drilling fluids which are compatible with the reservoir conditions and minimize formation damage • Define reservoir units within the Woodbine based on depositional patterns, reservoir geometries, and reservoir continuity • Define the regional distribution of various types of sandstone mineral, textural, and pore space properties in Woodbine reservoir rocks, particularly those associated with diagenetic clay phases • Properly locate development wells within a Woodbine field • Effectively interpret hydrocarbon-bearing Woodbine sandstones which appear “wet” on electric logs due to the presence of diagenetic clays in the pore network • Design proper well stimulation and/or fracturing treatments to efficiently produce hydrocarbons from Woodbine reservoirs • Aid in lease acquisition and in overall exploration and exploitation efforts for Woodbine wells • Assist in the selection of the number and location of injectors, composition of enhanced recovery fluids, and the treatment of injection and production wells for Enhanced Recovery programs within Woodbine fields.

Operators in the Gulf of Mexico are directing. their efforts toward the exploration and exploitation of deep reservoirs in the shelf area of the Gulf of Mexico. These reservoirs range in depth from 15,000 to 30,000 feet and are primarily Pliocene, Miocene, and Oligocene in age. These reservoirs present a challenge to operators and have an inherently high risk and cost. Traditional AVO seismic methods have yielded mixed results for identifying prospective target reservoirs. Explorationists must currently rely on identifying and evaluating prospects by projecting sand distribution from regional well control, identifying structural traps seismically, assessing the risk of reservoir quality, and evaluating the risk of seal integrity. All are challenging and aid significantly to the risk in drilling these wells. Our project focus is on three key areas to help reduce operator risk and increase success rates. Characterize the reservoir quality and petrophysical properties of deep shelf reservoirs: As. geological characterization of deep shelf reservoirs is critical to effective exploration, exploitation and reservoir quality prediction. Data on depositional facies, environment, rock types, mineralogy, pore structure, clay types, and petrophysical properties. will be determined on conventional, rotary and percussion sidewall cores and/or cuttings as applicable. Seal rock evaluation: Seal and potential seal rock material from conventional cores, rotary sidewall cores, percussion sidewall cores, and drill cutting samples will be evaluated in terms of seal rock properties. Methods used to determine seal capacity are: mercury injection capillary pressure, thin section, x-ray diffraction, and SEM analysis. An evaluation of seals in terms of lithology, log response, pressure regime, thickness, facies, areal extent, etc. from multiple wells and horizons will provide critical information needed to evaluate seal risk. Predict reservoir quality of deep shelf reservoirs in prospective (undrilled) areas: Geocosm will work. with the Integrated Reservoir Solutions Division to provide reservoir quality predictions using the Touchstone™ reservoir quality analysis and prediction system. Touchstone™ incorporates an integrated suite of diagenetic and petrophysical models that simulate sandstone reservoir properties through geologic time and can be used to predict reservoir quality away from well control. Important controls on model results include sandstone depositional texture and composition and subsequent temperature, depth, and fluid overpressure histories. Touchstone™ incorporates process models that are calibrated using petrographic, core analysis, and burial history data for analog samples. Calibration model development will be included as part of the project and will be performed by Core Laboratories..

This study focus is on determining the depositional facies of slope and deepwater sandstone reservoirs, along with their petrographic and petrophysical properties in the deepwater blocks of the Gulf of Mexico. In addition, detailed paleontological analysis is performed on core and drill cutting samples in order to place the cored intervals into a stratigraphic framework. These types of data and interpretations, integrated into a regional database, significantly enhance operators’ understanding of these deepwater reservoirs for improved exploration and exploitation efforts. All of this data, besides being provided in individual well reports, can be accessed in an Oracle™ database application via the Internet.. CHANDELEUR AREA. BRETON SOUND AREA. MAIN PASS AREA. The study area encompasses the blocks extending from the East Breaks Area to the Desoto Canyon Area. Participants in the project are required to contribute conventional cores from four (4) wells located within these deepwater areas. Conventional cores from existing wells may be contributed, as well as cores that are taken from exploration and exploitation wells that will be drilled in the near future. Newly-cored wells provide material suitable for the measurement and determination of an extensive array of petrophysical properties. The spectrum of deepwater reservoir rock types and their geological and petrophysical properties have been compiled into a catalog format to serve as reference analogs for more accurate estimates of formation parameters when evaluating non-cored reservoir intervals. Frequent core workshops and a series of technical talks are conducted so that the participants can meet with Core Laboratories’ deepwater team and examine, firsthand, the cores and associated data. In addition to the geological and petrophysical evaluation of cored reservoir intervals, this project also examines the seal characteristics of a spectrum of Deepwater GOM fields. The objective of this component of the study is to enhance evaluation of seal rock quality and aid in the calculation of seal capacity. The resulting database aids operators in their risk assessment of hydrocarbon columnar heights. Samples have been taken from fifty (50) deepwater fields from cores in the study. Data used to evaluate these deepwater seals are: high pressure mercury injection capillary pressure, thin-section petrography, x-ray diffraction, SEM analysis and Laser Particle Size analysis. These data along with reservoir parameters are used to determine seal capacity of the underlying reservoirs and will provide critical parameters for determining seal capacity of deepwater oil and gas seals in their depositional context. In addition, Core Lab has compiled a Wilcox provenance dataset from our Texas and Louisiana Wilcox Regional Studies and from Mexican outcrop samples.

MEXICO. This project was designed to optimize operators’. exploitation of down-dip, geopressured, Frio gas reservoirs in south Texas. Operators in this trend indicate that are having problems in the formation evaluation, well completion, stimulation and production aspects of down-dip Frio gas wells. These problems include but are not limited to the following: • Recognition of pay versus non-pay (lowresistivity contrast) as a result of pore system clays, shaly bioturbated reservoirs, and/or thin-bedded reservoirs • Petrophysical evaluation and reserve estimates • Prediction of permeability for the assessment of formation damage and production performance. • Casing collapse associated with rock compressive strength failure after fracture stimulation and drawdown • Rock-fluid compatibility, well completion and stimulation designs • Reduced permeability and porosity associated with pore volume compressibility during production. These problems have cost companies millions of dollars and can only be solved from the geological, petrophysical and geomechanical analysis and evaluation of either conventional cores or rotary sidewall cores. Cores from sixteen (16) wells were thoroughly analyzed in this fashion. The resultant data was used to calibrate open-hole logs and dipole sonic logs (e.g. MAC) in order to better predict rock types and properties essential for formation evaluation and proper well completion and stimulation designs. These rock types and their measured petrophysical and geomechanical properties serve as analogs when evaluating new reservoirs in wildcats or field step-outs. • Eigh teen ( 18) wells • Con ven tion al an d r otar y sidewall cor e.

T. his gas and oil producing shale reservoir has proved to be challenging in terms of reservoir characterization, predicting producibility potential, estimating ultimate recovery, and optimizing fracture stimulation techniques. Many companies either do not have or have limited rock property data that are crucial for understanding these reservoirs. Therefore, in order to properly evaluate and explore these gas and oil producing shales, appropriate types of rock property data need to be measured and integrated with log data, stimulation techniques, and production test information.. These integrated data sets and case histories will provide operators with the critical parameters to optimize their exploitation of the Eagle Ford Shale and reduce finding and development costs. The primary objective of this project is to provide operators with measured geological, petrophysical, geomechanical, geochemical, and production properties of the Eagle Ford Shale in order to improve their formation evaluation and to optimize stimulation and production. Understanding the similarities and differences in these shales on a regional basis is the key to successful exploration and exploitation. The resultant database will be an invaluable tool to operators in evaluating, comparing, and designing completion and stimulation methods for the Eagle Ford Shale.. 21.
