Drilling
Geophysicist Markos Sourial discusses advances in seismic imaging, the challenges of modern data processing, and what they mean for the next wave of subsurface professionals.
This research aims to develop a fluid-advisory system that provides recommendations for optimal amounts of chemical additives needed to maintain desired fluid properties in various drilling-fluid systems.
This paper describes development of a high-temperature water-based reservoir drill-in fluid using a novel synthetic polymer and customized with optimal chemical concentrations and sized calcium carbonate.

The London-based company is seeking to restructure more than $3 billion in debt as it struggles to find work for its offshore fleet. -
Achieving and sustaining performance drilling’s intended benefits—improved drilling efficiency with minimal downhole tool failures and the associated reductions in project cycle time and operational costs—requires new protocols in drilling-system analysis.

A Canadian company reports that it has drilled and completed a historic horizontal well in Saskatchewan.
-
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.

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.
