Drilling
Equinor cites confined gas behind casing and calibration issues in investigation of Troll field well control incident.
This paper provides an account of the design, implementation, and operational insights from an enhanced geothermal system proppant stimulation targeting a volcanic, dry rock setting with an approximately 330°C bottomhole temperature.
This study evaluates the feasibility of drilling a closed-loop, unconventional geothermal system in the Pannonian Basin basement of Romania.

Stories from the IADC/SPE Drilling Conference look at how the next generation of engineers is performing, the hottest well ever drilled, and the art of translating drilling numbers into executive reports. -
As leaders in digital drilling analysis push into real-time data analysis and digital controls, they are finally confronting data-quality problems. Humans are better than machines at dealing with ambiguous readings.
-
Sensor technology in the oil industry changes infrequently. Improvements in MEMS sensor technology are creating rapid momentum toward the use of tiny, rugged, and inexpensive sensors to replace larger, costlier, and more fragile legacy-technology sensors in directional drilling.
-
As the resources that the industry develops become increasingly challenging, access to a broader range of options and new and developing approaches allows more-efficient and -effective recovery.
-
The influx-management-envelope (IME) concept is an advanced, innovative way to assess influx conditions in managed-pressure-drilling (MPD) operations, offering an improved tool for the decision-making process.
-
Current long-reach technology already has a large effect on oil recovery. Many possible improvements, however, remain, and we see new contributions every year.
-
A producer and a service company have collaborated to develop a downhole system to merge multilateral technology and intelligent completions to create “smart laterals.”
-
This paper reviews the technology trends in cement-job evaluation using logging tools and considers the main advantages and concerns associated with each technology.
-
As I read through the abstracts and papers that have been presented in the past year, I notice several key themes: verification of cement placement, development of new materials as a barrier, development of new additives to improve the cement barrier, and enhancement of existing techniques.
