- Opened the Bakersfield office for Pinnacle in 1995, serving as a consultant for a wide range of major and independent clients, and developing long-term relationships with many.
- Assisted with fracture treatment design, treatment supervision, on-site fracture pressure analysis, post-frac evaluation and the integration with fracture diagnostic results.
- On location for thousands of hydraulic fracture treatments, in diverse fracturing environments ranging from:
- Nearly all California formations that are fractured, including, diatomite, naturally fractured siliceous shale, sandstones with permeability ranging from 100+ mD to <0.1 mD
- Tight gas intervals <0.1 mD spread around the U.S. and the world
- Horizontal wells at depths ranging from 1,000 to 14,500 feet, with fracture staging strategy ranging from 16 stages per well across a 2,000-foot lateral, to 1 stage/well into a 3,000-foot lateral
- Formation depths from 300 ft to 18,500 ft, covering the fracture closure stress range from 150 psi to 19,500 psi, and temperatures from 90Â° to 350Â°F
