Drilling/completion fluids
A fundamental research study is conducted to confirm the potential usefulness of chelating agents in dispersing settled barite, emphasize the complex nature of the factors that control this process, and provide a solid basis for future studies aimed at optimizing dispersion methods in industrial applications.
A universal, automated approach to condition-based maintenance of drilling rig mud pumps is developed using acoustic emission sensors and deep learning models for early detection of pump failures to help mitigate and reduce costs and nonproductive time generally associated with catastrophic pump failures.
Computational fluid dynamics modeling is used to gain better understanding of filter-cake formation in inclined and vertical well drilling operations under elevated temperature and pressure, highlighting the importance of controlling fluid invasion to optimize drilling performance.

This paper details a gravel packing operation in the Martin Linge field in the North Sea that marks the highest density carrier fluid openhole gravel pack completed successfully worldwide, setting a new standard for well completions in challenging high-pressure environments. -
This paper describes results of a study indicating that an enzyme/in-situ organic acid generated cleanup system was effective at degrading filter cake for a water-based-mud field sample, reflected in the obtained return permeability of nearly 83%.

Typically, oil and gas producing wells are abandoned toward the end of their life cycles with reservoir pressures depleted compared with the virgin pressures. Carbon capture and storage projects, however, present different operating conditions.
-
This paper presents the concept of a supervisory and advisory system dedicated to support the detection of abnormal events and to provide guidelines for fluid treatment.
-
This paper describes the success of using a new low-equivalent-circulating-density organophilic clay-free inverted emulsion fluid in gas reservoirs at elevated temperatures and with differential pressures up to 4,500 psi.
-
This paper describes a systematic full-scale test program to study and optimize solids-control efficiency with hollow-glass-beads drilling fluids.

At every stage, well-construction projects must be concerned about those aspects to establish measurable barriers for preventing issues. Therefore, drilling and completion fluids are critical for achieving project goals and ensuring operations are executed as planned.

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.
