Well integrity/control
To enable a fully interventionless approach, a barrier-rated tubing-hanger valve has been developed to eliminate slickline intervention and minimize associated risks and operational time.
This paper aims to present thoroughly the application of subsurface safety injection valves in extremely high-temperature environments.
This paper introduces a novel optimization framework to address CO2 injection strategies under geomechanical risks using a Fourier neural operator-based deep-learning model.

The authors of this paper investigate the risk of containment loss for a leaking well using a 1-sq-mile section of the Denver-Julesburg Basin. -
This study evaluates well integrity and CO2-leakage risk in wells penetrating a CO2 storage reservoir in Malaysia.
-
The authors of this paper develop a model that can predict well-risk level and provide a method to convert associated failure risk of each element in the well envelope into a tangible value.
-
HiberHilo will be used to monitor remote oil and gas wells in Papua New Guinea, providing real-time performance and safety data.
-
The paper presents a time-domain electromagnetic tool capable of quantifying four barriers individually and inspecting a fifth barrier qualitatively.
-
This paper describes an approach to estimate and remove guided-wave noise from array hydrophone data to improve accuracy of leak-source locations.
-
The paper describes a sensing system using distributed fiber optics that showed promising preliminary results for use in detection of riser gas in the form of kicks.
-
A study of a limited number of decommissioned oil and gas wells in England found no evidence of methane leaks, including four wells found to be leaking in an earlier study.
-
SponsoredWell-monitoring technology gives oil companies the data and insights to boost production and derive maximum value from oil and gas wells.
-
This paper presents a well-integrity-management system developed for a high-pressure/high-temperature gas field in southwest China.
