Drilling
This paper presents a case study of a tool-free fishbone fracture stimulation technology using sand jetting and acidizing in openhole wells, providing a technical solution for low-permeability and complex-lithology carbonate reservoirs in the Middle East.
This paper presents a case study of oriented tubing-conveyed perforation followed by an acidizing operation to overcome technical challenges posed by a depleted reservoir targeted for a carbon capture, utilization, and storage project.
This paper details a trial involving the deployment of a transportable coiled tubing (CT) unit capable of holding 30,000 ft of high-strength 2⅞-in. CT.

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.

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.
-
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.
-
This paper discusses a new, comprehensive cuttings-transport model designed to enable safe and improved hole-cleaning operations.
