Well integrity/control
This paper describes the evolution of the operator’s initial PWC (perforate, wash, and cement) abandonment projects performed in deepwater Brazil.
The authors reach conclusions that the industry should define a standard testing method to improve swelling performance, including validation of repeatability, to complement existing guidelines.
This paper presents the development of an advanced simulation tool aimed at providing a better understanding of the complex fluid-displacement phenomena present in well-cementing processes.
-
An influx-detection-at-pumps-stop (IDAPS) software was developed to provide early warning of abnormal flowback conditions during connections. -
This paper presents a new technology and methods that can detect leak locations in a well and illustrate the flow profile of the leak.
-
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.
-
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.
-
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.
-
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.
