Topic: A digital-cuttings drill-down, with examples from the Geolog Americas Nanushuk-Torok Regional Cuttings Consortium
Speaker: Dr. Guy M. Oliver, Director of Data Science & Energy Transfer at Geolog Americas, Houston Abstract: Drill cuttings are an invaluable source of quality organic and inorganic geological data and yet are often underutilized. This talk will focus on the importance and usefulness of cuttings data for hydrocarbon habitat understanding, with examples from Geolog’s new Nanushuk-Torok Rock and Fluids Regional Cutting Dataset which when complete, will hold over 200 wells worth of Nanushuk-Torok cuttings data (circa 15,000 data points) across the entire ‘North Slope Super Basin’ (after Masterson & Holba, 2021). Key to the understanding of this petroleum play is more regional data and interpretation associated with reservoir and source rock, type and quality.
As part of this dataset Geolog Americas with the support of the GMC and AOGCC, recently collected and analyzed for organic and inorganic content, 98 drill cutting samples from the Nanushuk and Torok intervals of Umiat Test Well-11. The data presented reveals some key, new findings regarding source rock type and facies, as well as interesting data relating to reservoir quality. For example, biomarker and source rock quality data suggest 2 different sources or source facies, a possible baffle zone may have inhibited the vertical migration of hydrocarbons, and reservoir quality data suggests differences in clay speciation across the Torok and Nanushuk Formations which may inhibit reservoir quality.
These types of data from the Nanushuk – Torok Formations are currently being consistently measured across the entire North Slope Super Basin as part of Geolog’s new Nanushuk-Torok Rock and Fluids Regional Cutting Dataset. This rich dataset when combined with other data such as 3D seismic will assist the Energy Industry in better understanding this potentially prolific Nanushuk-Torok Play and help to reduce some of the uncertainty surrounding source rock type & facies, and reservoir quality/facies. Speaker Bio:
Dr. Guy M. Oliver is the Director of Data Science & Energy Transfer at Geolog Americas, Houston and has been passionate about Drill Cuttings for the last 25 years, having written and presented many articles on the subject. Part of Guy’s current role at Geolog centers around creating rich, consistently measured, digital and easily accessible regional databases utilizing cuttings data and Geolog’s proprietary methodology for sample preparation and analyses. Key to this is a strong belief that cuttings provide a valuable source of information for reservoir and fluid analyses that are fundamental for petroleum systems understanding.
Guy received his BSc Geology Degree from Cardiff University, Wales in 1991, his MSc Petroleum Geology from Imperial College, London in 1992 and his PhD in High Resolution Sequence Stratigraphy & Early Diagenesis, Plymouth University, England in 1996.
