Organize and lead multi-functional peer reviews to support and improve field development design.

Monitor operating expenses to operate and maintain wells to produce the highest volumes of oil and gas at the lowest cost.

Prepare annual volumes and expenses for budgeting.

Monitor and analyze well tests and production curves.

Gather, perform calculations on and analyze data such as well tests, fluid levels, bottom-hole pressures, and decline curves to assure efficient producing and equipment utilization.

Coordinate all aspect of new completions, especially design of fracture stimulation.

Work closely with multidisciplinary team in planning and conducting field studies.

Prepare requirements for well construction, develop well designs for new wells and provide technical assistance to drilling staff to ensure that each well is completed in a safe and efficient manner.

Provide economic evaluation to support fast-paced development decisions and work closely with drilling, completions, and production teams.

Develop and implement efficient reservoir engineering and organizational practices.

Provide on the job coaching and mentoring to help develop capabilities of team members to enable them to grow technically and perform their job effectively and efficiently.
