Well integrity/control
For more than a century, LSU has shaped petroleum engineering education, but few assets showcase its impact like the PERTT Lab. With six deep test wells and rare reservoir-depth gas-injection capabilities, the facility is helping drive breakthroughs in well control, carbon-dioxide injection, and next-generation energy technologies.
This study identifies critical knowledge gaps in wellbore integrity and underscores areas that require further investigation, providing insights into how wellbores must evolve to meet the technical demands of the energy transition.
This study illustrates the new capabilities, tailored for carbon-dioxide storage applications, of a modeling framework that provides a quantitative, risk-based assessment of the long-term integrity of legacy plugged and abandoned wells.

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.

SponsoredWith more surface facilities and infrastructure in oil and gas fields, well casing integrity is becoming an even bigger challenge. This article sheds light on the optimum way to deal with the increasing casing integrity challenges in the Middle East through field monitoring and time-lapse casing-integrity and corrosion-inspection logging.

Prior to proceeding with a contract to fulfil a rigless P&A campaign for Sasol in Mozambique, BiSN designed a field trial to prove the effectiveness of its bismuth plug technology. Although the technology had been used in 19 countries by BiSN for a variety of downhole applications, it had not yet been qualified for use in Mozambique.

Over a 10-year period, sensors monitoring the motion and loads near subsea wellheads have been mounted on more than 300 drilling campaigns. Integrity parameters were calculated to assess whether subsea conductors provided the intended amount of support during drilling operations. In several of these campaigns, loss of conductor support due to integrity issues was obse…

This paper presents an intelligent tube solution that combines data retrieved by the sensors with the actual resistance of each pipe in the well to allow adjustment of production parameters while ensuring installation safety.

This paper introduces a method using a Bayesian network to aggregate trends detected in time-series data with events identified by natural language processing to improve the accuracy and robustness of kick and lost-circulation detection.
