Well integrity/control
This paper addresses the deployment of an external protective coating with a rough surface profile in wells identified as susceptible to common cementing issues.
This paper provides examples for planning and execution of primary and remedial managed pressure cementing in deepwater drilling operations.
This paper presents a lost-circulation model used during design and job-evaluation phases to accurately predict top of cement and equivalent circulating densities.

This paper presents laboratory testing and application of a resin-cement system designed to be placed as a tail slurry to provide enhanced mechanical properties compared with a conventional slurry. -
This paper describes a foamed cement solution designed and implemented to cement shallow intermediate casing strings in a heavy oil play in Northeast Alberta.
-
This paper presents an evaluation of geopolymer cementing for use in oil and gas wells, specifically in the primary cementing of liner strings in the Permian Basin.
-
The authors challenge the traditional planning and execution of interventions, both from an operational and commercial standpoint, and examine where room exists for significant improvement in the industry
-
This paper provides insights into the technical and economic viability of repurposing oil and gas wells for geothermal energy production for direct heating.
-
This paper addresses the challenges related to well control and the successful implementation of deep-transient-test operations in an offshore well in Southeast Asia carried out with the help of a dynamic well-control-simulation platform.
-
Typically, oil and gas producing wells are abandoned toward the end of their life cycles with reservoir pressures depleted compared with the virgin pressures. Carbon capture and storage projects, however, present different operating conditions.
-
The authors of this paper describe a suite of technologies that enables enhanced well robustness and performance modeling and monitoring of carbon storage facilities.
-
This paper presents the proof of concept of artificial-intelligence-based well-integrity monitoring for gas lift, natural flow, and water-injector wells.
-
This paper defines conditions for optimized well-diagnostics investigation and describes a rigless solutions for common well-barrier failures and lessons learned from operator field trials.
