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

Falling oil prices are the acid test of drilling efficiency. SPE Technical Director Jeff Moss of ExxonMobil talks about ways to build in lasting savings as part of this special report. -
The latest example of the offshore sector's march toward automated wellbore construction will take shape later this year in the North Sea.

Well RXY is located in Cairn’s Ravva offshore field in the Krishna-Godavari Basin in India. One goal for the field was significant crude production by means of a secondary reservoir section.
-
A contest where teams of college students design and build an automated drilling rig able to deal with hazardous obstacles in a test block, showed how a small change can be engineered to matter.

Crude oil output has more than doubled in New Mexico over the last 4 years, making it the No. 3 producer among US states, but a January change in state leadership to Democratic control has industry executives fearing tougher regulations are coming.

SponsoredNew extreme environment ultracapacitor technology will allow directional drillers to eliminate lithium from their entire supply chain. These advanced ultracapacitors can be coupled with downhole turbine generators to provide reliable downhole power without the need for lithium.
-
Since the 1980s, many technical works have focused on improving the ability to detect hydrocarbons inside the riser and safely remove them from the system. This trend gained extra momentum with the advent of systems such as riser-gas handlers and managed-pressure drilling.

Operators face a dilemma in balancing the need for mud weight (MW) to remain below the fracture gradient to avoid losses, while also providing sufficient density to block influxes into the well.
