From geology to production: a completion optimization case study from Cleveland Sand, Oklahoma

This study is based on work performed on horizontal wells in the Cleveland Sandstone Formation. Previous work describes the technique of using automated, quantitative mineralogy (RoqScan) to analyse drill cuttings and derive rock property and elastic pseudo-logs to customize completion designs. We expand on these findings to utilize the estimated elastic rock properties in a proprietary coupled reservoir-geomechanical simulator. The geometry of the individual cluster fractures can then be computed during pumping to investigate different treatment stage designs. The study supports the idea that optimized stage spacing will result in the development of a larger SRV and higher production.
