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.

Industry awaits the results of Apache’s Maka Central-1 exploratory well offshore Suriname, where high expectations follow the rapid exploration success of neighboring Guyana. -
Multistage horizontal well designs were first implemented in the Bakken in 2007. Since then, more than 12,000 wells have been completed in either the Middle Bakken or Three Forks zones.
-
This paper compares the performance of three mature-field horizontal infill wells, one of which is completed with autonomous inflow-control devices (AICDs).
-
A new 3D drillstring model determines the static and dynamic behavior of bottomhole assemblies (BHAs) in realistic wellbores.
-
This paper presents dynamic simulations, prototype testing, and field-test results of a BHA component that isolates the upper part of the BHA from HFTO.
-
This paper examines multiple factors that can affect the severity of stick/slip and measures their actual effect.

Field N is a complex heavy-oil field in the north of the Sultanate of Oman. The dynamic behavior of Field N is characterized by strong aquifer and is dominated by bottomwater drive.

ADNOC’s drilling subsidiary has increased its rig fleet to 95 and plans to add “dozens” more by 2025.
-
By using the four converter-battery systems, the operator estimates it will be able to reduce the runtime of the rig’s on-platform diesel engines by 42%, cutting CO2 emissions by 15% and NOx emissions by 12%.

Scaling buildup inside wellbores is a serious production problem that dramatically reduces the well productivity index. This issue has a significant cost across the industry, mostly associated with loss of production or additional operations such as well intervention.
