Drilling/completion fluids
This paper describes an openhole wireline-logging operation in a deepwater Gulf of Mexico well in a high-pressure/high-temperature slimhole environment using water-based reservoir drilling fluid.
The authors of this paper present results of a study that examined formation-damage mechanisms caused by drilling fluids in tight reservoirs in onshore oil fields in Abu Dhabi.
This paper reviews the successful application of a mud-cooling and managed-pressure-drilling system in a high-pressure/high-temperature well to explore the potential of a Mesozoic carbonate platform in the Nile Delta of Egypt.

The authors of this paper describe a project that demonstrated the feasibility of using deep-learning and machine-learning approaches to introduce camera-based solids monitoring to the drilling industry. -
In this paper, β-cyclodextrin polymer microspheres, generally used for drug release and wastewater treatment, are evaluated as an environmentally friendly ultrahigh-temperature filtration reducer.
-
This paper describes the qualification and first deepwater drilling application of a novel aqueous reservoir drilling fluid at temperatures greater than 320°F.
-
Significant reserves additions may be realized if the risks associated with drilling in such harsh conditions can be managed effectively. Design and development of a new generation of drilling fluids able to fulfill all of the attributed functions under extreme pressure and temperature conditions is one of the key requirements for unlocking these resources.

This paper describes a high-density high-pressure/high-temperature brine-based drilling fluid that provides long-term stability and solids-suspension properties for extended periods of time.
-
This paper discusses the results of extensive laboratory tests used for the customization of a reservoir drill-in fluid and a delayed breaker—and their field performance—for two deepwater gas-injector wells.

Against a backdrop of global uncertainty and challenging economics, well integrity subject-matter experts have continued to prioritize human and environmental safety in production while pivoting their skills toward areas of growing importance such as carbon capture and sequestration. New technologies and simulation methods have allowed the authors of the three SPE pap…

Recent developments in drilling-systems automation provide a multitude of opportunities to have real-time monitoring of drilling-fluid properties and early diagnosis of drilling-fluid-related complications that might arise while drilling. Coupled with closed-loop control of surface and downhole drilling-fluid properties, automated monitoring of fluid properties would …
-
This paper presents experiences from an automated drilling-fluids-monitoring initiative and resulting real-time hydraulic measurements and models for automatic drilling control.
-
This paper presents the design and functionality of an apparatus that measures directly and automatically the pressure/volume/temperature (PVT) behavior of the drilling fluid contained in a pit.
