2022-2024 (Midland, TX, USA) Diamondback Energy, Permian BasinSenior Reservoir Engineering Advisor- Led team focused on providing best Permian data for asset teams and business development evaluations. This involved reviewing multiple data sources, SQL, interfacing with asset teams, working with IT, and responding to feedback and requests in a timely manner.- Generated quarterly peer reviews and reviewed with senior management.- Improved scripts for generating data for data analytic software models. Built new data analytic models. Evaluated multiple development options and reviewed results with teams.- Continued to improve scripts for spacing and metric calculations.- Evaluated EOR proposal from third party.- 2024 Steering Committee member of SPE AI Forum.- Mentored summer intern (1). Mentored engineers in training (2).

2021 (Midland, TX, USA) Diamondback Energy, Permian BasinSenior Reservoir Engineering Advisor- Completed a review of data analytic software options for production forecasting.- Selected one software and led team through pilot evaluation. This included gathering data for the model build, building the model(s), and predictions. Utilized data analytic software to evaluate many different development options for different areas.- Continue to update Python scripts for spacing and metric calculations quarterly.- 2021 Co-Chair of SPE Midland Basin Forum.- 2021 Co-Chair of SPE Delaware Basin Forum.- Evaluated multiple EOR proposals from third parties.- Evaluated multiple vendor proposals / software from third parties.2019-2021 (Midland, TX, USA) Diamondback Energy, Permian BasinSenior Reservoir Engineering Advisor- Began learning Python in 2019. Built Python scripts to bring in directional survey data and calculate spacing between all wells in the Permian Basin. Built Python scripts to calculate parent-twin-child metrics. Built Spotfire projects to generate Gun Barrels including metrics. Provided tools and training to teams. Continued improvement in scripts / tools.- Completed Aries economic Lookbacks on Development Program including identifying key drivers. Completed Vintage evaluations. Reviewed both multiple times with teams and senior management.- 2020 Co-Chair of SPE Unconventional EOR Forum.- Mentored summer interns (2).

- Led all aspects of Unconventional EOR (produced gas injection) Pilot project internally, with GTI, and with the GTI Consortium (12 operators, 5 majors) focused on the Wolfcamp, Midland Basin. (HFTS-1)

- Spacing and Completion Optimization: Completed multiple evaluations including economics of spacing and completion optimization for different areas and landing points. Coordinated reservoir simulation projects with Halliburton, Schlumberger, and consultants (RTA) with same focus. Performed reservoir simulation with same focus.- Discovered Child wells for Laredo. Coordinated Parent Child project with UT. Discovered interesting production characteristics of well configuration and completion sequencing.- Completed acquisition evaluations.- Frac Impacts: Analyzed frac impacts. Built a database of frac impact performance information. Provided clear understanding of the results of frac impacts on Laredo development program. Field tested different ideas to try and mitigate frac impacts.- Data Analyses / Spotfire: Went from novice to expert in some areas of Spotfire, including setting up scripts for complex tasks. Company lead for getting key data organized into databases across disciplines. Built automated Spotfire script to calculate spacing between wells. Ruths Ai DCA Wrangler experience. Routinely provided performance related data for Investor Reporting.
