Well integrity/control

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.

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…

This paper examines current practices and developing trends in well construction and describes an alternative cementless approach to the discipline.
