Denver, Colorado, US

• Responsible for field development work creating and integrating geological maps, petrophysics, logs, and seismic for prospect development in the STACK and SCOOP areas of the Anadarko Basin.
• Participated in multi-disciplinary and upper management meetings to design and review well plans, assess prospect geology, and finalize well plans for permitting.
• Planned and executed complex horizontal wells in the Springer, Mississippian, and Woodford formations, integrating zone targeting, risk reduction and multidisciplinary team best practices for drilling and production.
• Made significant contributions to record-setting Springer Formation wells using Schlumberger's Periscope HD tool.

Irving, Texas, US

• Highly skilled at properly landing wells within target formation, understanding well plans and plays in a 3-dimensional sense.
• Led the lookback review of underperforming Wolfcamp D well, determined the root cause and wrote SOP to increase production on future wells.
• Tested and implemented automated geosteering tools using StarSteer.
• Used control points from the interpreted formation structure based on drilled horizontal wells to re-grid surfaces and adjust seismic surveys.
• Made critical contributions to the re-design of a tool built in-house to quickly compare horizontal wells against offset data in a 2-dimensional view for increased correlation accuracy.
• Identified critical flaws in workflow and tools and corrected issues through tool updates and development of standard operating procedures.

Irving, Texas, US

• Gained an understanding of the financial concepts that build profitable business.
• Collaborated with Reservoir Engineering and Field Development teams to calculate Net Resource Potential and Net Asset Value.
• Assisted reservoir engineers interpret geological maps and understand the potential geologic impact on differences in Estimated Ultimate Recoveries between adjacent areas.Performed production forecasting for Permian.

Irving, Texas, US

• Planned horizontal wells, working them toward maturation and approval.
• Worked with Regulatory, Land, Reservoir Engineering, Drilling and Field Development teams to ensure wells were legal and executable with low risk.
• Performed lookbacks to improve well plans and drilling performance on offset wells. Resulted in cost reductions by eliminating trips out of hole for new tools; enhanced production due to accurate wellbore placement in.
• Selected pad designs for optimal development of all pay zones in our Midland Basin acreage.
