Lower operating expenditures and a changing asset mix helped UKCS operators cut average production costs by 9% year over year, despite relatively flat production levels, according to the NSTA.

This paper identifies opportunities and risks associated with repurposing an offshore oil and gas platform for green hydrogen production. Various technical scenarios were investigated for the case study platform, and their profitability was determined using economic calculations. In addition, all the submodels were compared with standard decommissioning costs for reco…

This paper presents a flexible, highly cost- and energy-efficient method of gas separation and CO₂ capture from many different gas mixtures with a large range of CO₂ concentrations.

This work introduces a novel predictive methodology combining historical metocean data with real-time riser analysis for shallow water dynamically positioned rig operations.

This paper documents the testing, integration, and field deployment of a metal expandable packer used as an openhole toe isolation plug in a deepwater well under high-pressure, high-temperature conditions.

This paper presents an approach for safe, efficient, and cost-effective legacy well reabandonment.

This paper discusses the successful execution of two openhole gravel-pack completions in two Gulf of Mexico fields with depleted reservoirs.

As the pace of new discoveries slows and high-quality prospects become harder to find, oil companies may need to rely more heavily on mature fields to maintain production and support future supply.

New agreements for exploration and production in Africa include activity in the Orange Basin offshore Namibia, offshore Angola, Senegal, and Côte d’Ivoire. In the Gulf of Mexico, a memorandum of understanding for deepwater evaluation was signed between Woodside Energy and PEMEX and Viridien initiated its Walker Ridge Reimaging Extension. TotalEnergies provided a targe…

A shared digital mindset across subsurface, subsea, and drilling and wells is accelerating well planning at Vår Energi.
