Drilling
The agreement focuses on improving operational efficiency and consistency through advanced digital tools and real-time data integration.
An innovative approach uses a random-forest-based framework to link logging-while-drilling and multifrequencey seismic data to enable dynamic updates to lithology parameter predictions, enhancing efficiency and robustness of geosteering applications.
Oil and gas companies drilled 75 “high-impact” wells in 2024, representing 5.2 billion BOE.

Petrobras has cut in half the time and cost of drilling some wells using its patented True One Trip Ultra Slender (TOTUS) concept. The technique can be used in certain mature fields of the postsalt where geological and reservoir characteristics favor its application. -
Discussed are real-world examples of the less often considered but valuable environmental benefits delivered via MPD.
-
The new geothermal project development company will offer expertise in subsurface and drilling, project development, and risk mitigation.

Valaris, formed in 2018 after the merger of Houston-based Rowan Cos. and London's Ensco, faces fallout from the oil-price drop, canceled or delayed drilling programs, and contract and day rate modifications.
-
Citing impacts from COVID-19, Noble Corp. is entering into a prearranged agreement with its bondholders that will give it a fresh start with a new line of credit.
-
An intelligent drilling optimization application performs as an adaptive autodriller. In the Marcellus Shale, ROP improved 61% and 39% and drilling performance, measured as hours on bottom, improved 25%.

The complete paper presents a technical discussion of a new microsampling technique for LWD and a corresponding wellsite technique to provide compositional interpretation, contamination assessment, reservoir-fluid compositional grading, and reservoir compartmentalization assessment.
-
A well was drilled into a prospective unconventional mudstone play offshore Norway. Two of five coring runs were successful while the rest yielded little to no core recovery. Subsequent investigation of the core substantiated that the coring issues largely had natural causes.
-
Logging-while-drilling remote operations has hit a wall. Since the outbreak of COVID-19, there is an increased demand for personnel with multidisciplinary skill sets to work on offshore rigs. But the demand cannot be satiated.
