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 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 test information. These integrated data
sets and case histories provide operators with the critical parameters to optimize their exploitation of these reservoirs and reduce finding and
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:
