... casing. To build it, a cement evaluation log was run to investigate the presence of cement in annulus surface-production casing. A perforation gun was then run into the well to make some holes in production casing below leaking points. Injectivity and communication test was then performed to check...

... Abstract Wireless communication in subsurface wells and reservoir has been a major challenge in ensuring robust data transmission, and reliable communication between the sensors. Challenges from the multiple reflection as well as other external factors, makes subsurface communication a unique...

Therefore, establishing a digital workplace has set an approach in a way drilling and completion teams handling internal and external communications, collaborations and content management to support drilling and completion activities. In order to understand more in depth, this paper, as a part...

... with setting a plug inside the tubing below the targeted perforation depth and punching the tubing to create tubing-casing communication. The tubing was then flushed with surfactant and weak acid to remove any potential contaminants. The cement was then bullheaded from the surface through the tubing...

... Abstract It is a great challenge for well integrity when a high volume gas production well is found with the production casing broken near the wellhead hanger resulting in high pressure communication between Annulus A and B. The objective of the paper is to propose a new solution to establish...

... well data, with WST-3C clean-up delayed, allowing for a longer observation time of the WST-3D clean-up. Clear communication with operations and flexibility in the plan allowed these changes to be made with no impact to the quality of the interference testing data. The wells deemed most important...
