• Manage the plan of development for >64k acres within Eagle Ford Karnes and De Witt County position. Tasked with revitalizing the development for the 2022 $3 billion Ensign acquisition where we are now outperforming.
• Optimize wells through complex SA extensions, azimuthal bends, land agreements, completion design, well spacing, fault navigation, and targeting that led to adding over 37,980’ of completable lateral worth over.
• Led efforts to plan Marathon Oil’s first Eagle Ford U-Turn wells. Leveraged industry data to justify DLS within the U-bend, utilized ChatGPT and Python to optimize well plans for unit development and increase accuracy.
• Performed competitor intelligence across the Eagle Ford. This included creating a Spotfire dashboard to view all offsets operators remaining inventory by pulling Enverus’s placed sticks through Snowflake and allowing.
• Push drilling group to incorporate innovative techniques to incrementally capture value. Recently drilled the 2nd longest 2-string step-out in the Eagle Ford, ~2,850’, reducing location, rig MOB, and completion cost of.

Houston, Texas, United States

• Lead operations geologist for >125 wells across all L48 assets including, Permian, Oklahoma, Bakken, Eagle Ford, Louisiana, and West Texas. Selected as lead operations geologist for high-profile exploration plays.
• Worked with the Permian asset team to eliminate a casing string by evaluating offset operator data and understanding of geological controls on our casing program.
• Worked beyond operations geologist role for exploration group staking 7 wells and 2 produced water pounds which were utilized to reduce completion costs.

Oxford, Ohio

Houston, Texas Area

• Performed resource play and hybrid play evaluation.
• Correlated, divided, and mapped intervals of interest based on well logs.
• Integrated geochemical data to evaluate kerogen type and thermal maturity.
• Calibrated individual wells for use in 1D model to evaluate burial history.
• Calculated STOOIP values for volumetric analysis based on petrophysical work. Involved calculating and mapping net pay, average porosity, and average water saturation.
• Evaluated core and thin sections for contact identification and lithological characterization.

Lexington, Kentucky Area

• Aided in the assessment of acquisition and mergers by evaluating upside potential and reserves for a given company, including the design of geological models for their given acreage/field and evaluation of production.
• Developed a program using VBA in MS Access and Excel to automate decline curve analysis for single well EUR using public production data which was used as an exploration technique. The program assisted in the discovery.

Cincinnati

• Supported several projects including research on the Permian-Triassic by working in the geochemistry lab of Dr. Thomas J. Algeo. Duties included performing loss on ignition, total organic carbon and total inorganic.
• Participated in weekly meetings where current research was discussed with other students and visiting faculty.
