Rc. Nolenhoeksema et al., WATERFLOOD IMPROVEMENT IN THE PERMIAN BASIN - IMPACT OF IN-SITU STRESS EVALUATIONS, SPE reservoir engineering, 9(4), 1994, pp. 254-260
We evaluated in-situ-stress magnitudes and directions to support water
flood improvement programs in McElroy field and North Westbrook Unit.
In-situ-stress and hydraulic-fracture directions coincided with direct
ional floodwater effects. This information contributed to successful w
aterflood realignment programs.
