Currently, numerous oil and gas companies are directing their efforts toward the exploration and exploitation of the "Eaglebine" section in East Texas. The "Eaglebine" section is the interval from the base of the Austin Chalk to the top of the Buda limestone. It consists of the Woodbine sandstones and the underlying Eagle Ford Shale both of which are targets for horizontal completions. These liquids-rich reservoirs have proved to be challenging in terms of drilling, 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 reservoirs, 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 "Eaglebine" and reduce finding and development costs.
The Integrated Reservoir Solutions Division of Core Laboratories is proposing to interested companies participation in a multi-company, geo-engineering study of the "Eaglebine" reservoirs. The project is an extension of our highly successful Eagle Ford Shale study of South Texas and our Woodbine Sandstone study of East Texas. The project consists of the characterization and evaluation of numerous conventional cores, rotary sidewall cores, and drill cutting samples taken from multiple wells targeting the "Eaglebine" section. Specifically, this prospective section will be analyzed for geological, petrophysical, geomechanical, geochemical, and production properties. These 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 the section, but also on other operator's wells.
