Haynesville & Bossier Shale Evaluation

Currently, numerous oil and gas companies are directing their efforts toward the exploration and exploitation of the Haynesville and Bossier Shale in East Texas and North Louisiana. 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 are crucial for understanding these reservoirs. Therefore, in order to properly evaluate and explore these Gas 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 Haynesville and Bossier Shale 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 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. 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 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 North Louisiana.

Each company joining the project will be required to contribute core material from two (2) wells for analysis, evaluation and inclusion into the database. The cores must be through the Bossier Shale and/or Haynesville Shale. It is anticipated that conventional cores from a minimum of twenty (20) wells will be included in the project. In addition, the conventionally cored wells (key wells) will be supplemented by 20 to 30 reconnaissance wells represented by drill cuttings and/or rotary sidewall cores. Each company will also be obligated to contribute drill cuttings and/or rotary sidewall cores from two (2) reconnaissance wells.
