Optimize stimulation design, perforation, and well spacing
The newly acquired and rapidly processed acoustic data helped finalize stimulation design and perforation strategy as well as provided insight into potential drainage patterns influencing future well placement. Stress data from the processed logs and geomechanical model indicated that the regionally persistent shale break between the reservoir sands may act as a barrier to height growth. The data enabled placing perforations across both sandstones, and the fracture treatment was applied in a single stage.
Determining the principal east–west horizontal stress orientation influenced planning for future well spacing and gave insight into the minimal depletion observed in the appraisal well. Propagation of the fracture would align with the current horizontal stress orientation and was modeled to provide elliptical drainage patterns because of the tight nature of the reservoir. This approach to field development planning has resulted in well spacing that is tighter in a north–south direction to account for eccentricity.
