Abstract
Investigators publish new report on Machine Learning. According to news reporting out of Grand Forks, North Dakota, by NewsRx editors, research stated, "Active reservoir management (ARM) through brine extraction can reduce pressure buildup during large-scale implementation of carbon capture and storage (CCS) projects. This study used machine learning (ML)-assisted approaches to analyze bottomhole pressure (BHP) responses to various brine injection and extraction scenarios." Financial support for this research came from DOE's Office of Fossil Energy's Carbon Storage Research Program through the National Energy Technology Laboratory (NETL). Our news journalists obtained a quote from the research from the University of North Dakota, "Field monitoring data were collected over a 2-year operation period at two injection wells and one extraction well (about 400 m away) as part of a Brine Extraction and Storage Test (BEST) in the North Dakota portion of the Williston Basin. Injection activities increased the BHPs at the injection wells by around 0.70 MPa (similar to 100 psi) during the operation period. Extraction activities demonstrated the capability to decrease the BHPs at the injection wells by approximately 0.21-0.34 MPa (30-50 psi) depending on the ratio of the extraction and injection well flow rates (the " extraction ratio " - a normalization procedure used in the analysis). The pressure reduction provided by the extraction well equated to 30-50 % of the pressure buildup at the injection well."
