Directional/complex wells
This paper discusses the development of a multientry, multistage fracturing system and its advantages over traditional openhole multistage fracturing solutions.
This paper proposes a methodology for preventing drillstring fatigue and failure in deep wells with large shallow doglegs.
In this paper, the authors propose a regression machine-learning model to predict stick/slip severity index using sequences of surface measurements.

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. -
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.

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.
-
A surface-based torque and tension sub (TTS) was used to perform measurements while drilling several extended-reach horizontal wells.
-
The development of multilateral wells and long-reach wells has become important to maximizing recovery for many oil fields.
-
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.
-
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 Burgan reservoir consists of vertically stacked channel sands along with a fault network connected to the aquifer and contains highly viscous reservoir fluid.
