• Design and review well plans, assess prospect geology, and analyze data for development of unconventional reservoirs in the Marcellus Shale in Pennsylvania. Participate in multi-disciplinary and upper management meetings to review plans and opportunities for improvement.• Provide geologic guidance while drilling horizontal wells.• Conduct surface geologic mapping and take strike-dip measurements in the vicinity of future pad sites for well-planning purposes.• Perform data analysis on geological and petrophysical datasets to understand production drivers and create plots and maps for the field development plans.• Develop tools with Python and full-stack technology to deploy apps for sharing information via data visualizations with supporting analysis for understanding value drivers.• Led efforts to collect and present geologic data in a virtual data room.

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 success.• 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.• Assembled a multi-disciplinary team to solve drilling problems with our Jo Mill horizontal program. Suggested a re-targeting approach that maintained focus on highest pay zone and best drilling lithology.• Leveraged skills from prior roles to mentor junior geoscientists.

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 Basin JV assets, and all related reconciliation required.

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 pay zones.• Selected pad designs for optimal development of all pay zones in our Midland Basin acreage.
