Due to differences in phase behavior, both well design and operational procedures would be impacted and needs to be revised. Traditional well control procedures are not necessarily applicable in CCUS wells without...

An automated drilling system is capable of providing automated functionalities such as FDIR or automated drilling procedures, but the drilling strategy and associated short, medium and long-term decision-making are in the hand of the driller. In contrast, an autonomous drilling system takes...

... is a combined effort between operators and service providers. In the D.J. Basin, well drilling times are between 48-60hours. A 10-hour trip for failure can account for over 20% of well time. Onshore operations have benefited from focusing on performance metrics. To achieve some metrics, drilling procedures have...

... rings are switched to Geotextile mesh. The caps are reassembled, and the inner casing pressure is ramped back to 25 MPa in 30 minutes. The nitrogen steady-state permeability measurement procedure is conducted after the pump’s flowrate is reduced to zero (steady state for temperature and inner...

... procedures (such as core floods) are often not practical to use with such samples since they take too long. In this study, we introduce a new laboratory method for measuring the oil recovery in a huff-and-puff IOR process in shales. In huff-and-puff IOR, a treatment additive and a gas are typically injected...
