Drilling
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
This paper aims to assess the effectiveness of using advanced integrated production-data-analysis techniques for condensate-rich tight gas fields.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.

Through the end of October, 38 rigs have been retired this year. Predicting future rig attrition is not an exact science, but certain metrics help identify those rigs.

Digitalization and automation successes are here to stay. Instead of making small incremental steps in well construction operations, allowing disruptive shifts can lead to tangible performance gains in efficiency, safety, and well integrity.

There is a growing interest in using nanocomposites to improve drilling-fluid rheology. In recent years, an additive derived from a sequence of graphene-based materials has been reported. The progress of these graphene derivatives has been used as a paradigm for water-based drilling fluids.

Advances during the past decade in using convolutional neural networks for visual recognition of discriminately different objects means that now object recognition can be achieved to a significant extent.
-
Our understanding of drilling with better software, instrumentation, machines, computer vision, downhole tools, and robots will continue improving the economics of horizontal wells, and the trend is set to continue. This is good news for the geothermal market.

This paper reports the effect of sodium dodecyl sulfate modified graphene (SDS-Gr) on the rheological features, fluid loss, and swelling inhibition mechanism of clay.
-
This paper describes a low-impact, nonaqueous drilling fluid (LIDF) designed to minimize equivalent circulating density (ECD) increases and associated risks in deep water by reducing the effect of cold temperature on fluid viscosity.
-
The complete paper describes an offshore artificial island project northwest of Abu Dhabi in which drilling limits were extended continually by adopting new technologies and practices in an extended-reach-drilling (ERD) campaign.
-
This paper discusses a new, comprehensive cuttings-transport model designed to enable safe and improved hole-cleaning operations.

The number of units that have been cold stacked since 2016 are in the double digits. Reactivation costs for these rigs range from $40 million to $100 million. Given current rates and contract durations, most of these are unlikely to return to work.
