Geological Modeling for Well Spacing Determination and Field Development in the Permian Basin

Samuel Rogers


Unconventional asset development strategies have taken many directions over the past few years including landing point selection, engineered vs geometrical stage spacing, seismic derived reservoir quality indicators, longer laterals, operational execution including zipper fracs and increasing proppant loadings, with current trends towards smaller well spacing, tighter cluster spacing, and multiple wells targeting different vertical benches. The list of completion and development options to test in the field are so large now that operators are rapidly moving toward calibrated geological models to assist in examining with multiple completion scenarios, and validation of the best options in focused field tests. Rather than using wells as the experimental platform, actual data, models, and analysis are being used to pick the best targets and influence drilling and completion programs.

This presentation will demonstrate an Asset Development workflow that provides the structure for systematic evaluation of the many completion design scenarios by incorporated multiple data scales (core, log, seismic, operational and production history) with 3D geological models to understand production drivers, including investigation of the role of structure, natural fracturing, lithological/rock variability and coupling to stress profiles, hydraulic fracture propagation and sensitivity of operational fracturing parameters. While some single well scenarios showed higher production as a stand-alone case, asset development in the stacked Wolfcamp pay for optimal volumetric recovery is depending more on the combination of well production, drainage volume, well-to-well interference, well cost, and lateral placement.


Samuel is an internationally experienced Petroleum Engineer, Project Manager and Business DevelopmentManager with a proven track record of delivering results during 15+ years of experience in the Oil and Gas industry. Leadership and technical abilities have been demonstrated across assignments in diverse countries and cultures such as Algeria, Canada, Ecuador, United States and Brazil. He is a Professional Project Manager (PMP) and has working across several business segments to lead, manage and coordinate teams in the profitable execution of large multi-faceted projects. His technical expertise includes applied data mining
applications, stimulation evaluation for completion optimization processes, and the integration of multisource/ frequency data for Field Development Planning (FDP) workflows.

Professional Experience

 Team leader for first calibrated complex fracture and well interference projects in the Eagle Ford and Permian – conducted over 2013 to 2015. Supported proprietary Earth Modeling projects across the entire both the Delaware and Midland Basins to rank acreage and predict/map EUR from down spacing.
 Conducted bid strategies and drafted proposals for various consulting projects in the Brazil, while managing the execution of the first unconventional / tight gas exploration study by PetroTechnical Services in Brazil.  The project was completed under budget, on schedule, and exceeded client expectations for quality – achieving an income before tax (IBT) of 21.3%.
 Project Manager for full field simulation study / field development of a complex Carbonate reef structure.  The study incorporated real-time ESP data and increased field oil production by 36%, while adding 3 Million BOE of proven reserves.
 Production Team Leader responsible for designing a workflow utilizing response surfaces as a proxy for compositional simulation models of the world’s largest carbon-dioxide miscible flood and sequestration project in the Weyburn Field (carbonate, Late Mississippian).
 Collaborated with the Well Services segment to develop a novel interpretation methodology for real-timemeasurements recorded during matrix acid stimulation in carbonate reservoirs – trademarked as ACTiveMatrix. New revenue generated in Canada for 2008 was $12.7 Million and the technology has beens u c c e ssful utilized in Mexico, Asia, Italy and the Mid-East.
