Well integrity/control
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.

This paper presents a well-integrity-management system developed for a high-pressure/high-temperature gas field in southwest China. -
The authors describe a study in which leakage-rate modeling was performed to identify and evaluate the associated risks for designing a remedial action plan to safeguard a CO2 storage site.
-
The authors write that polymeric additives are effective in the design of complex systems to house important chemical reagents under challenging conditions.

Against a backdrop of global uncertainty and challenging economics, well integrity subject-matter experts have continued to prioritize human and environmental safety in production while pivoting their skills toward areas of growing importance such as carbon capture and sequestration. New technologies and simulation methods have allowed the authors of the three SPE pap…

SponsoredShell needed an easy-to-use, simple well monitoring solution. Could an IoT wireless solution measure up to a classic wired approach?
-
Hiber, an industrial Internet-of-Things startup, announced that it has signed an agreement with Shell to provide well-integrity monitoring solutions globally.

SponsoredWellbore deformation can occur at any stage in the life of a well. Whether a result of changes in temperature, pressure or tectonic forces, wellbore deformation may result in serious downhole issues such as restricted access for interventions or the loss of well integrity that may ultimately lead to premature well abandonment and significantly reduced economic perform…

A wellbore repair tool was successfully deployed to rectify collapsed tubing in a remote well off the coast of Papua New Guinea.
-
This paper’s authors describe the development of a coiled tubing (CT) nitrogen-lift design in which CT and geothermal reservoir simulations were combined to overcome modeling limitations.
