Directional/complex wells
Improved bit and bottomhole-assembly technologies and designs have helped turn what used to be record-breaking drilling runs into routine expectations.
This paper provides an account of the design, implementation, and operational insights from an enhanced geothermal system proppant stimulation targeting a volcanic, dry rock setting with an approximately 330°C bottomhole temperature.
This study evaluates the feasibility of drilling a closed-loop, unconventional geothermal system in the Pannonian Basin basement of Romania.

The boom in organic shale plays has revealed the critical need to size hydraulic-facture treatments correctly to achieve commercial success. -
This paper discusses the first deployment of an ICD system combined with an OBC system for a workover operation in a mature producer well in the Kingdom of Saudi Arabia.
-
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.
