BS Industrial Management, University of Arkansas, Fayetteville, 1980

MS Mechanical Engineering, University of Colorado, Denver, 1993

Career Brief:

2003-current – MuleShoe Engineering, Principal Engineer providing engineering consulting services to the Oil & Gas industry and to various manufacturers of Oil & Gas products.  Focus on low-pressure operations, deliquification/artificial lift, Coalbed Methane, Compression, and facility design.

1993-2003 – BP America Production Company, Facilities Engineer for CBM wells and gathering facilities in the San Juan Basin of Northern New Mexico.  Identify opportunities to increase revenue, design projects to implement opportunities, manage construction, and oversee operations.  Projects have included nine gathering-system expansions, four major compression facilities, de-bottlenecking 85 high-rate wells for very-low-pressure operations, and installation of 50,000 horsepower of rotary-screw compression on well sites.  The projects have added over $1,300 million (NPV13) for a gross expenditure of $41 million.  Ongoing operations include innovations in the design of pigging equipment, using pipeline modeling to define pigging schedules, gas-well deliquification projects, corrosion and scale interventions, and extensive use of a Geographical Information System to reconfigure gathering-system valves to correct operational problems.

1991-1993 – Amoco Production Company (now doing business as BP America Production Company), Team Leader and Consulting Engineer for San Juan Basin Outside Operated Team.  Restructured the portfolio of outside-operated properties from an $18 million annual profit into a $200 million annual profit by applying effective property management, good partner relations, and appropriate engineering interventions.  Supervised a staff of 5 and acted as consulting engineer in the areas of reservoir engineering, reserves estimating, production engineering, and facilities engineering. 

1980-1991 – Amoco, Production Systems Analyst in General Office and field settings.  Project manager and system designer on 35 major software-development projects ranging from the Worldwide Reserves Inventory System (that defines the way hydrocarbon reserves are calculated, stored, and reported and has been in use for over 20 years) to the Automated Maintenance Scheduling System that formalized maintenance processes in 15 plant and field locations and required acting as a maintenance consultant for the operations.  Project-management responsibilities included supervising up to 45 employees on software projects that ranged upwards of $5 million expenditure.  Field support included a system that proved to the State of New Mexico that their Proration Order should be eliminated and it was.

1971-1977—U.S. Navy, Nuclear Mechanical Operator (Pay grade E-5), USS Truxton CGN35.  Acted as a plant operator, engine room supervisor, and maintenance supervisor.
