Drilling
The company said that its AD-300, a 50-m-high automated island drilling rig that walks between wells, was delivered 3 months ahead of schedule.
A report commissioned by Havtil, the Norwegian Ocean Industry Authority, calls for better dialogue regarding pore-pressure uncertainty and higher-end drilling techniques like managed pressure drilling as methods to reduce the risk of well-control events.
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.

The authors of this paper write that the use of high-angle wells through anisotropic shale formations represents a promising approach to improving oil recovery while reducing the overall number of wells required. -
Extended-reach drilling (ERD) and complex wells have emerged as pivotal techniques, enabling access to previously unreachable reserves. ERD allows operators to access oil and gas reservoirs far from the drilling site, minimizing the environmental footprint and optimizing resource recovery.

This paper highlights the continuous improvement of multilateral technology used in the Middle East by demonstrating how the application of a multilateral well strategy is a proven and reliable method to reduce time-intensive operations.

Cementing and zonal isolation remains an important topic to operators and service providers alike. Additionally, an increase in the number of papers with both academic and field-driven content shows that there is no lack of initiative for operators to materially improve on existing methods and technology.

This paper addresses the deployment of an external protective coating with a rough surface profile in wells identified as susceptible to common cementing issues.
