Drilling
The project with ExxonMobil used closed-loop drilling and digital well-construction technologies.
ExxonMobil's Jason Gahr uses the five stages of grief to explain how the upstream industry should respond to the rise of AI.
A multidimensional Wiener process approach predicts casing remaining useful life, enabling safe, cost-effective well life extension and repurposing for carbon dioxide injection, CCS, and geothermal applications.

The maritime technology company successfully completed a remote deadweight audit for a semisubmersible oil and gas drilling rig. Believed to be the first of its kind, the remote survey was developed in response to travel and social-distancing restrictions imposed during the COVID-19 pandemic. -
Brazil’s national oil company details the results of 6 years of real-time drilling monitoring. The next step is to move toward optimization, then automation.

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.

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.

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.

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%.
