- Geologic Consultant to an international engineering firm that did reservoir characterization, reservoir simulation, and provided facilities and secondary recovery decision direction on world class Cretaceous carbonate field in UAE, currently producing over 250,000 BOPD. As a result of the recommendations of the study the Government of Abu Dhabi’s Onshore Operator let a contract with a value in excess of 1 billion dollars for field wide upgrades. In addition, they just recently announced a large contract to upgrade the takeaway capacity of the field.
- 3D SEISMIC PROJECT – TYLER COUNTY, TEXAS
Working Interest participant in 3D dataset. Drilled and completed two successful Yegua test with multiple pay zones by sidewall core and open-hole log analysis.
- 3D Seismic Survey South Texas
Participant in an approximate 60 square mile 3D survey in South Texas to evaluate Wilcox and shallower sands. Approximately twelve wells have been drilled within this survey.
- Jurassic Prospect East Texas
Generated a prospect covering approximately 10,000 acres based on subsurface control, seismic, offset production and a pre-fracture stimulation test in the key well. Apache Corporation acquired the property in 2002 and drilled 6 wells in the area, 5 of which were successful completions in the Cotton Valley Lime, with potential pay behind pipe in the Cotton Valley and Bossier sands. XTO also drilled 2 successful Cotton Valley Lime wells.
- Stockman Field Area - Shelby County, Texas
Calvin was instrumental in negotiating an approximate 7,000 acre farm-out from a major independent oil & gas company. Calvin and its’ partners re-entered 1 well and drilled 9 additional wells on this prospect. To date, pay zones have been found in the Pettet, Travis Peak, Upper and Lower Cotton Valley sands, Haynesville Shale and Haynesville Lime.
