Drilling
More than 900 drilling and well professionals from 30+ countries gathered at APDT 2026 in Bali to explore how AI, automation, and advanced well technologies are driving safer, smarter, and more efficient drilling across Asia Pacific.
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.

Many of us work in strong functional environments, where all too easily we can deploy solutions that have the potential for repercussions on other aspects of well design, construction, completion, and performance. -
The operator of an offshore jackup rig in the North Sea required safe and efficient deployment of the completion string without killing the well during tripping.
-
What is observed when an unconventional well is fractured is often at odds with what was expected by those who planned the job.
-
The Shearwater field is a deep, high-pressure/high-temperature (HP/HT) reservoir located in the UK Central Graben of the North Sea.
-
A pilot project carried out by Hess demonstrates how quickly automated drilling technology is able to take a rig from the bottom of the pack in terms of performance and push it to the top.
-
This paper focuses on experimental methods quantifying water-based muds and investigating effects on particle bridging, filtrate invasion, and permeability.
-
Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.
-
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
-
The inventor of a new water-based drilling fluid believes the chemical process involved with his technology opens up natural fractures as drilling takes place to increase production in shale formations.

Does formation-damage coreflooding give a good representation of damage that occurs downhole? For those of us who are actively involved in coreflooding, this is a common question to be asked.
