Drilling/completion fluids

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%.
