Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.
This paper presents the characterization and comparison of a metakaolin-based geopolymer as a candidate treatment for remedial operations in oil and gas wells versus conventional state-of-the-art materials.
This paper describes the development of a method of predicting drillstring-friction coefficient during tripping operations that can be used for early warning of stuck pipe.
-
The engineering and operational planning to ensure that no uncontrolled hydrocarbon releases occur during the execution of subsea big-bore gas wells are described. -
Well control is built around huge steel machines, but the future of the business is digital. Data have become a critical asset as operators and service companies work to increase the safety and reliability of their products and operations.
-
A new blowout preventer design shows potential for delivering much greater shearing power than current BOPs. The design is simpler and more efficient than current BOPs.
-
Precise casing-wear prediction is important for improving well integrity and longevity, while simultaneously making casing designs more cost-effective. There are no industry guidelines for casing-wear prediction. This article presents a validated predictive model.
-
Operators in the North Sea have been concerned about the ability of the cement sheath to maintain sealing integrity because of the increasing number of reported failures in mature wells. This paper presents results from a new laboratory setup to visualize the source of issues.
-
This paper describes experiences, challenges, and approaches to solving the problems related to creating an advanced early kick-detection system suitable for floating mobile offshore drilling units.
-
On the basis of safety performance results achieved through automation downstream, an operator set out to achieve the same advances in its upstream business.
-
The tragic blowout of Macondo has triggered many technical and managerial developments in the field of well integrity.
-
The North field offshore Qatar was observed to have a chance of inner annuli becoming charged with shallow-gas pressure with possible communication to other annuli, which was thought to be a well integrity concern.
-
Despite multitier safeguards, blowouts occur. When such accidents happen, rate estimation is an important and daunting task.
