Drilling/completion fluids
This paper establishes that the use of a dual-gradient fluid column during the running of large casing in an extreme-reach deepwater well is an effective method to overcome drag and enable the casing to reach total depth.
In this paper, a case study is described in which a software solution enabled prescriptive optimization of well delivery using a physics-informed machine-learning approach for predictive identification and characterization of well-construction risks.
Two critical facets of the discipline of well control and wellbore integrity—decarbonization and groundbreaking automation of essential processes—are highlighted in the three primary paper selections presented at SPE and SPE-affiliated conferences during the past year.

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.
-
In this paper, alternative approaches to solids characterization are presented that lend themselves better to automation and real-time monitoring than API retort measurement.

Few industries contain as many phases, steps, and levels of interface between the start and end product as the oil and gas industry. It therefore is hardly surprising that communication, in all its varied forms, is at the very heart of our business.
