Directional/complex wells
This paper describes the development of a method of predicting drillstring-friction coefficient during tripping operations that can be used for early warning of stuck pipe.
This paper proposes a time-series analysis approach to build a reliable, easy-to-use tool to automatically detect stuck pipe accurately and early.
This paper investigates condensate-banking effects on well performance by conducting field-modeling studies on Delaware Basin deep Wolfcamp condensate producers using compositional simulation models with hydraulic fractures.

The authors of this paper describe a project in which Raleigh frequency-shift distributed strain sensing monitored during production in a far-field observation well was translated to an estimated pressure profile. -
This paper presents the study, resulting recommendations, and a proposed change in standard bottomhole-assembly configurations to reduce service-quality-compromising incidents and productive time lost from jar twistoffs.
-
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 domain expertise and technologies in the oil and gas industry such as integrated project planning and operating, extended-reach drilling (ERD), high-pressure/high-temperature drilling tools, multilateral drilling and completions, geomechanics, flow and thermal dynamics modeling, and artificial intelligence have been fueling the ongoing march for new records on ERD…
-
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.
