Geomechanical Study of Bakken Formation for Improved Oil Recovery
The objective of this paper is to outline the methodology proposed to determine the in-situ stress field and geomechanical properties of the Bakken Formation in Williston Basin, North Dakota, USA to increase the success rate of horizontal drilling and hydraulic fracturing so as to improve the recovery factor of this unconventional crude oil resource from the current 1％ to a higher level. The success of horizontal drilling and hydraulic fracturing depends on knowing local in-situ stress and geomechanical properties of the rocks. We propose a proactive approach to determine the in-situ stress and related geomechanical properties of the Bakken Formation in representative areas through integrated analysis of field and well data, core sample and lab experiments. We plan to use Kaiser Effect technique to estimate in-situ stresses. CDISK method will be used to determined fracture toughness. Geomechanical properties will be measured following ISRM suggested methods. By integrating lab testing, core observation, numerical simulation, well log and seismic image, Intelligent Geomechanical Logging and Imaging methods are proposed to estimate geomechanical properties in locations where no results of lab testing and core observation are available.
