Drilling
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 study aims to thoroughly assess the influence of various completions, fracturing stimulation, and intrinsic reservoir properties affecting the productivity of 10 major unconventional plays while uncovering insights and trends unique to each play

The work presented combines a fundamental-physics approach with field data to identify the root cause of drilling failures in Paleocene and Eocene injectite-sand intervals. -
Large areas of the North Sea contain Cretaceous sediments, which form a massive hard layer of chalk that historically has presented a major drilling risk and expense to operators in the area.
-
Implementation of new technology can require that leadership and key team members be willing to step outside their comfort zones.

Australian technology developer MezurX is touting its newly introduced flow, density, and mud monitoring system as a significantly better alternative to the widely used Coriolis meter.

Seminole Services’ Powerscrew Liner System is a new expandable-liner hanger that is set with torsional energy from the topdrive.
-
On the basis of safety performance results achieved through automation downstream, an operator set out to achieve the same advances in its upstream business.

The standard for progress in shale development has been the drastic reduction in the number of days needed to drill a well, from more than 20 to less than 5 in some unconventional plays. But some question whether it has become a misleading metric for an industry needing more productive wells.
-
The only wells that are straight or follow a smooth curve are in the pictures in well plans. Real wellbores are shaped by the mechanics of directional drilling tools, the skills and attention of drillers, the force of gravity, and the path followed by hydrocarbon-rich seams of rock.
-
With the innovation of extended-reach and directional drilling, running casing and liner strings has become increasingly difficult.

While rotary-steerable systems (RSSs) dominate the offshore directional-drilling markets, the land-based markets are still dominated by conventional directional-drilling tools. This paper presents a new RSS that is being designed and tested specifically for the onshore markets.
