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

A specialized fibrous material was examined and was found to be effective for hole-cleaning applications. -
This paper describes the path to implementation of full casing rotation during primary cementing jobs.

Fluid identification, a critical process in fluid sampling, continues to be a challenge in temperatures above 350°F. At temperatures up to 450°F, fluid identification is currently achieved by bubblepoint and compressibility measurements, which cannot quantitatively measure contamination levels of the sample fluid. A possible solution involves using pyroelectric detect…

This year, in the presence of enormous challenges, the selected papers demonstrate step changes both in efficiency and in the results of cementing operations.

Shale producers have learned in recent years that their fracture plugs may not be holding up as well as they thought. One of the first operators to realize the true scope of the issue is now sharing the pathway it took to solving it.

Anomalies in heart function can be diagnosed in real time by measuring an electrical signal. Petroleum engineers have adapted the concept to diagnose anomalous drilling conditions in real time using a shock signature recorded downhole.

Schlumberger has won a $480-million contract to drill 96 oil wells in southern Iraq for the country’s Basra Oil Company and for ExxonMobil, which operates the giant West Qurna-1 field with partners from Iraq, Japan, Indonesia, and China. West Qurna-1 is one of the world’s largest oil fields.
