Drilling
This paper presents laboratory-testing methods and evaluation criteria designed to improve understanding of both the origin and extent of formation damage associated with CO2 injection.
This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.

ExxonMobil will retain its equity stakes in ongoing Bass Strait projects even as it hands off its operatorship responsibilities to Woodside Energy. -
Thermal stimulation can accelerate the formation of shale creep barriers for long-term well integrity but only within a carefully controlled temperature window. This study identifies optimal thermal conditions for maximizing barrier performance while avoiding thermally induced shale damage.

Conflict‑driven price gains may be offset by higher costs, supply‑chain risks, and a limited appetite for new drilling activity.
-
While some idle wells may be brought back into production, many will be plugged and abandoned. This paper considers repurposing certain idle oil and gas wells by using their empty steel casing for the disposal of nuclear waste.

The companies' combined technologies enable real-time control of well placement, hydraulics, and rig operations.
-
Improved bit and bottomhole-assembly technologies and designs have helped turn what used to be record-breaking drilling runs into routine expectations.
-
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.
