Wellbore tortuosity is a term that has steadily increased in relevance to the oil and gas industry over the past decade, but its importance is especially clear in the current environment.

The success of any digital oilfield project is predicated on the quality of the data structure, acquisition, communication, validation, storage, retrieval, and provenance of the data.

To have the flexibility to treat both rich and lean gas wells [up to 100% gas volume fraction (GVF)], a new multiphase pump system has been developed by comparing the different boosting systems performance and analyzing well-by-well production scenarios.

Engineers thrive on making more from less, and this month’s paper selections highlight efforts to improve the efficiency of gas-production operations throughout the world.

The complete paper describes an experimental study performed to investigate the onset of liquid loading in a 6-in. production casing at various inclination angles.

To further reduce backpressure on low-pressure gas wells and increase reserves in a mature gas field, a gas-ejector project was evaluated and proposed.

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.
