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.

Software that offers turn-by-turn directions for drilling a horizontal well could drastically reduce the number of directional drillers. -
Advanced horizontal drilling, multistage hydraulic fracturing, and other technologies have helped make the Vaca Muerta shale oil and gas resource economically viable.
-
Multilateral wells with smart completions controlled by different flow-control technologies offer great operational flexibility, with each lateral able to be operated and optimized independently.
-
This paper demonstrates how the latest generation of connections has been tested and validated to extreme loads before being installed in the wellbore.
-
A North Sea field development included installation of long 4½-in. completion liners in the horizontal reservoir sections of each well. To minimize overall risk, the operator planned to use managed-pressure drilling (MPD).
-
Few locations present as many challenges for drilling as the Arctic. It is one of the most hostile environments in the world, with some of the most remote locations, the toughest logistics challenges, and the largest gaps in infrastructure on the planet.
-
This paper describes the first job in southeast Asia in developing horizontal-well placement in a turbidite environment.
-
A new rotary-steerable system (RSS) was designed to give geometrically greater dogleg-severity (DLS) capability while still being able to withstand the increased bending stresses.
-
This paper explores the applications, benefits, and value of a high-build-rate rotary-steerable system (HRSS) capable of delivering dogleg severity (DLS) greater than 18°/100 ft.
-
Advances made in horizontal and complex-trajectory wells demonstrate that, despite this historic downturn, the industry has kept innovating and optimizing to bring more-efficient solutions to the table.
