To help optimize pad size and gel loading for hydraulic fracturing, R. Lacy Inc. used a net pressure calculation based on observations made during minifracs run before each fracture stage. Optimized pad volume and gel loading yielded greater fracture length and improved productivity of these Cotton Valley gas wells in East Texas. The paper describes the design study, fluid efficiency, net pressure, dynamic fluid loss, designing a frac job, gas production, and lessons learned.
