Accomplishments & Highlights:
• Developed Encana’s 7,000’+ long lateral program in NLA by coordinating construction, drilling, completions, facilities, and midstream efforts for 50+ long lateral locations.
• Joined multiple fracture interference and drainage study groups to determine effective stimulation methods in areas previously impacted by hydraulic fracturing.
• Championed an innovative evaluation tool called the Value Assessment and Mapping Process (VAMP) that streamlined lease acquisitions and economic sensitivities.
• Implemented VAMP widely both internally and across business units across the company under the direction of C-suite level management.
• Enhanced VAMP programming to include parameters for portfolio management .
• Partnered with the Shale Technology Exchange Partnership (STEP) group as a key member and presenter for upper-level management meetings and companywide technical conferences.
• Designed and implemented the Bonds Ranch Pressure Monitoring Project, which monitored vertical pressure depletion for six permanent pressure gauges installed behind casing in the Barnett Shale.
• Launched and led the Mercer Ranch Downspacing Development Study comprised of ten horizontal wells drilled from two pad locations that were completed sequentially.
• Completed microseismic testing for seven wells, chemically traced four wells, two pressure transient tests, radioactive tracing, and production logging.
• Managed a reservoir stimulation study for Bonds Ranch while creating useable reservoir simulation models for the Barnett Shale.
• Mentored and trained seven newly-hired engineers and two summer interns in technical best practices.
Texana Development (New Areas) Group – 2008 to 2010:
• Managed development for the Haynesville Shale/Cotton Valley non-operated joint venture partnership with Nabors-First Reserve (NFR) in East Texas.
• Supervised Development Engineering efforts in EnCana-operated acreage located in Shreveport and Caddo Parrish, Louisiana.
New Texas Growth Group – 2008:
• Evaluated potential acquisition and divesture activities for the North Texas Team while managing and analyzing scientific studies and increasing well density evaluations.
North Texas Development Group – 2006 to 2007:

Southwestern Energy Company, Houston, TX
Led the West DeSoto Fayetteville Reservoir Engineering teams covering over one million acres in Western Arkansas, which included proposing drilling locations, completing reserves, forecasting production, generating and tracking AFEs, and implementing testing, analyses, and modeling for reservoirs.

Accomplishments & Highlights:
• Resolved liquid loading issues for 20+ restimulation candidates by establishing linear flow transient models that evaluated stimulation effectiveness and constructed a field personnel system that optimized production.
• Generated budget estimates in excess of $1B per year while constructing a regional stimulation plan, testing multiple stimulation technologies, and providing recommendations to senior-level management.

Senior Reservoir Engineer 5/1996 to 11/2005
Swift Energy Company, Houston, TX
Led Reservoir Engineering teams and produced property evaluations for both acquisitions and divestitures for Lake Washington Field in Louisiana and A.W.P. Field in Texas.
