Directional/complex wells
This paper presents a multifaceted approach leveraging precise rig control, physics models, and machine-learning techniques to deliver consistently high performance in a scalable manner for sliding.
This paper presents a study of trapped-torque incidents during drillpipe connection, highlighting contributing factors and root causes and proposing prevention and mitigation measures for these transient events.
In this study, a method was developed to analyze the effects of drilling through transitions on bit-cutting structures and construct an ideal drilling strategy using a detailed drilling model.

As part of a project that involves the use of four artificial islands to drill and complete more than 300 extended-reach-drilling (ERD) wells in a giant offshore oil field, several completion designs have been piloted for brownfield development. -
There is no doubt that horizontal and complex-geometry wells have contributed significantly to the reliable supply of affordable energy, resulting in improvements to the quality of life of people around the globe.
-
A surface-based torque and tension sub (TTS) was used to perform measurements while drilling several extended-reach horizontal wells.
-
West Africa has seen a significant shift in drilling activity, mainly in deep water. Many of the major international operators are carrying out important exploration-and-development activities there.
-
The combination of ultrasonic pulse-echo and flexural-attenuation measurements was adopted in this project in the South China Sea for cement-integrity evaluation.
-
The first multilateral well in a North Kuwait field has been drilled recently.
-
Complex reservoirs in the Junín block of the Orinoco oil belt of eastern Venezuela offer challenges in achieving higher production rates and maximizing extraheavy-oil recovery.
-
The development of multilateral wells and long-reach wells has become important to maximizing recovery for many oil fields.
-
The Burgan reservoir consists of vertically stacked channel sands along with a fault network connected to the aquifer and contains highly viscous reservoir fluid.
-
Tar mats are encountered in many Middle East carbonate reservoirs. In cases in which tar acts as a flow barrier between water and light oil, water injectors work most efficiently when placed horizontally immediately above the tar mat to maintain pressure support during production.
