Directional/complex wells
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 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 nontraditional methods to cure oil-based-mud losses in horizontal wells drilled in unconventional plays.

This paper discusses the first multilateral well with a Level-4 junction combined with an inflow-control device (ICD) planned, designed, and drilled in the Upper Burgan reservoir of Raudhatain field, north Kuwait. -
While rotary-steerable systems (RSSs) dominate the offshore directional-drilling markets, the land-based markets are still dominated by conventional directional-drilling tools. This paper presents a new RSS that is being designed and tested specifically for the onshore markets.

The only wells that are straight or follow a smooth curve are in the pictures in well plans. Real wellbores are shaped by the mechanics of directional drilling tools, the skills and attention of drillers, the force of gravity, and the path followed by hydrocarbon-rich seams of rock.

This paper offers insight into an integrated effort at combining analytical information, numerical well-test models, and geological evidence to explain the reservoir behavior observed in the Huntington field.
-
For thin-oil-rim reservoirs, well placement, well type, well path, and the completion methods must be evaluated with close integration of key reservoir and production-engineering considerations.

This paper gives the recommended MSF horizontal-well spacing for several development scenarios in Saudi Arabian gas-reservoir environments.

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.
