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.

This paper discusses a full-scale drilling test rig that allows comprehensive study of the influences of bit characteristics on high-frequency torsional oscillations (HFTO) for the first time. -
This paper discusses tools and techniques used to localize a tubing leak in a horizontally completed multilateral well, identifying the bore responsible for sand production and providing relative sand quantification at differing flow rates.
-
The authors of this paper discuss deep closed-loop geothermal systems as an alternative to traditional enhanced geothermal systems for green energy production that is globally scalable and dispatchable.

The objective of this paper is to review selected completions to provide insights for adoption of multilateral technologies, including lessons learned, operational experience, and recommendations.
-
This paper describes preplanning, execution, and results of drilling extended-reach wells with a large-bore design of 12¼-in. as the main stepout section and deploying 9⅝-in. casing at a shallow true vertical depth of 4,200 ft.

Geosteering is supposed to ensure the wellbore stays in the most-productive zone, but a recent study suggests it often misses the mark.
-
This case study presents results achieved in Romania, Mexico, and Kuwait with the use of a series of innovations featuring integrated bottomhole assemblies. A push-the-bit system combines high-performance drilling with precise directional control.
-
This paper highlights the potential of machine learning to be used as a tool in assisting the drilling engineer in bit selection through data insights previously overlooked.
