Numerous oil and gas companies in the Western Canadian Sedimentary Basin are directing their efforts toward the exploration and exploitation of gas and liquids-rich gas from the sandstone and siltstone of the Wilrich Member in the Lower Cretaceous Spirit River Formation. The Wilrich play ranks as one of the most economic natural gas plays in North America. Core Lab has been conducting highly successful joint industry projects evaluating analogous tight reservoirs for over 20 years.
Several companies have cored and evaluated the Wilrich potential on their leases over the years, with a marked increase in interest the last year. In order to properly evaluate and exploit this target, 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 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 Wilrich section in order to improve their formation evaluation and to optimize stimulation and production. Our work suggests that understanding the similarities and differences in the section 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. Specifically, the project objectives are as follows:
