Resin chemistry, including epoxies, phenolics, and furans, has been widely utilized in a variety of applications in well construction, completion, and production. This broad class of thermosetting pol...
As developed wells continue to produce, these completed assets undergo thermodynamic cycling consistent with the production life of the well. The constant loading on these wells induce stresses that a...
Here we are, at last, with the final piece of our series on Plug and abandonment of oil and gas wells. We went through legislation and design, guidelines and best practices, materials and the PWC® in...
EV’s video of the month comes from an operator in the middle east who had challenges that required an EV solution for two separate wells. Without the experience and technical capability of the EV eq...
TGT has recently taken its electromagnetic EmPulse® well inspection system to new, more complex and challenging levels with recent successful surveys on wells with very high-chromium tubulars. EmPuls...
This article is a direct result of inspiring presentations on a novel technology from the 2nd Annual Well Intervention Workshop for the Middle East in Abu Dhabi. What I picked up there, made me r...
CASE STUDY: OIL COMPANY CHALLENGE Perforate the inner 9 5/8 in. casing of a well whose bottomhole temperature ranged between 300°F – 400°F using the largest possible diameter gun system to delive...
A ghost from the past started hunting me when I went through my files. Ashamed of what I discovered I decided to tell everyone, especially young engineers, what not to do when setting a cement plug. ...
There are different definitions of Well Integrity. The most widely accepted definition is given by NORSOK D-010: “Application of technical, operational and organizational solutions to reduce risk o...
