Drilling
Co-owner Chevron confirmed the find at the Bandit prospect offshore Louisiana and suggested it may become a subsea tieback to existing faciltiies operated by Occidental Petroleum.
The Orange Basin and Gulf of Guinea will see most of the high-impact drilling activity planned this year in Africa.
ExxonMobil will retain its equity stakes in ongoing Bass Strait projects even as it hands off its operatorship responsibilities to Woodside Energy.

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.

Digitalization and automation successes are here to stay. Instead of making small incremental steps in well construction operations, allowing disruptive shifts can lead to tangible performance gains in efficiency, safety, and well integrity.

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.

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.
