Drilling
This paper presents the development of a digital tool for automatically analyzing the readiness of a borehole to accept casing. The tool integrates data-driven and physics-based models to indicate locations of risk along the wellbore.
Esgian analyst doesn’t expect tightening rig supply to drive a recovery until 2027.
Two new wells add 15,000 BOE/D of peak capacity to the London-based supermajor's North Sea production profile.

Our understanding of drilling with better software, instrumentation, machines, computer vision, downhole tools, and robots will continue improving the economics of horizontal wells, and the trend is set to continue. This is good news for the geothermal market. -
This paper reports the effect of sodium dodecyl sulfate modified graphene (SDS-Gr) on the rheological features, fluid loss, and swelling inhibition mechanism of clay.

This paper describes a low-impact, nonaqueous drilling fluid (LIDF) designed to minimize equivalent circulating density (ECD) increases and associated risks in deep water by reducing the effect of cold temperature on fluid viscosity.

The complete paper describes an offshore artificial island project northwest of Abu Dhabi in which drilling limits were extended continually by adopting new technologies and practices in an extended-reach-drilling (ERD) campaign.

This paper discusses a new, comprehensive cuttings-transport model designed to enable safe and improved hole-cleaning operations.

The number of units that have been cold stacked since 2016 are in the double digits. Reactivation costs for these rigs range from $40 million to $100 million. Given current rates and contract durations, most of these are unlikely to return to work.

When a plug gets stuck in a well, consider the cause. Often stuck fracturing tools are a warning sign of casing trouble. Companies that have investigated plug problems have been surprised by the findings.

Specifically targeting ingrained thinking, the selected papers demonstrate the game-changing results that can be achieved even when targeting long-established norms. They demonstrate everything that our industry should be proud of and what we strive for.

The complete paper provides an approach using machine-learning and sequence-mining algorithms for predicting and classifying the next operation based on textual descriptions.

Traditionally, a wellhead system requires a drilling lockdown sleeve (LDS) during drilling operations to ensure that the seal assembly is rigid and prevents dynamic movement. By eliminating the LDS, however, the operator will save multiple trips into the well.
