Drilling
While some idle wells may be brought back into production, many will be plugged and abandoned. This paper considers repurposing certain idle oil and gas wells by using their empty steel casing for the disposal of nuclear waste.
The companies' combined technologies enable real-time control of well placement, hydraulics, and rig operations.
Improved bit and bottomhole-assembly technologies and designs have helped turn what used to be record-breaking drilling runs into routine expectations.

This paper highlights nontraditional methods to cure oil-based-mud losses in horizontal wells drilled in unconventional plays. -
This paper presents a continuous passive magnetic ranging technique that can provide real-time distance and direction to the offset well while drilling without interrupting drilling operations.

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.
-
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.

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.
-
This paper provides examples for planning and execution of primary and remedial managed pressure cementing in deepwater drilling operations.
