Using the Relationship Between Geochemical and Pressure Data to Elucidate Produced Oil Sources and Movement in the Subsurface
Dr. Sarah Compton-FractureID
Abstract:
Understanding how and why fluids move in the subsurface is key to characterizing and most efficiently developing an operator’s acreage. In the DJ Basin, oil from the Niobrara and Codell likely has a common source, and their reservoirs are likely in communication with each other. Great Western Petroleum, a pure-play DJ operator, designed the Wilson project in 2019 through a structurally calm area, with one large graben cutting the full section along the toes of the wells, to characterize fluid movement in space and time. In 2020, data from eight parent wells on the nearby Postle pad was added. This pad is characterized by several faults cutting the full section at various spots along the lateral. The case studies show differences in fluid communication despite similar completion methods, perhaps relating to different structural settings.
Bio
Sarah Compton is a geoscientist in Morrison, CO who currently works full-time with FractureID and publishes the weekly AAPG tech and innovation newsletter called Enspired. She completed an NSF iCorps Starting Blocks cohort in spring of ‘23 and was invited to present her business proposition for a SAGE mentorship group, which she was awarded and is currently working with while she actively develops her own software. The target customer is small to medium operators, and she is happy to discuss that in more detail afterwards.
Sarah earned her PhD in geology from the University of Alabama, using linear inversions to focus on the impacts of different model setups of finite element models using Hekla Volcano in Iceland. Her MS and BS in geology were earned at IUPUI focusing on the crustal evolution of southern and southeastern California using igneous petrology.
