Drilling
Operators aren’t rushing to drill, even as the closure of the Strait of Hormuz drives oil prices up.
Drilling experts recently shared candid views on what will be required for their segment of the upstream business to move to the next stage of development.
This year, we observed a notable increase in activity centered on physical technologies, including cementing tools, zonal isolation barriers, and cement evaluation systems.

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.
-
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.

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.
-
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.
-
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%.
-
The advent of the rotary-steerable system (RSS) introduced an efficient way to drill both current and future wells. However, current tools still fail to replace positive displacement motors (PDMs).
