Subsurface DNA Diagnostics Aid Well Spacing Decision in the Permian

Speaker: Liz Percak-Dennett

Abstract:
Biota Technology mission is to deploy DNA sequencing to maximize reservoir economics. The application of DNA sequencing in the oil and gas industry provides operators with a non-invasive, high-resolution data source to track subsurface fluid movement by examining subsurface DNA originating from microbial communities within the subsurface. To date, the technology has been applied on over 300 wells in the Permian Basin resulting in over 8500 analyzed samples and 250,000 unique subsurface DNA markers. Deployment of this technology has resulted in increased reservoir understanding including monitoring of drainage heights and well: well communication over time. In this presentation Dr. Liz Percak-Dennett, Technology Director at Biota Technology will speak to Subsurface DNA Diagnostics basics, field workflow, data analysis, and provide several case studies of practical applications in U.S. shale.
