filter cake

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 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%.

Laboratory studies performed for evaluation of filter cake breaker fluid exposed limitations with a conventional test approach.

A well-flux surveillance method to monitor and ramp up production for openhole standalone screen completions is described that optimizes production by considering risks of production impairment and screen-erosion failure.

This paper covers the 7-year history of drilling-fluids application in a reservoir drilling campaign offshore Abu Dhabi, from the early use of a solids-free, brine-/water-based mud to the recent application of nondamaging, nonaqueous fluids (NAFs) with micronized acid-soluble ilmenite.

This work focuses on the laboratory techniques for developing, assessing, and analyzing innovative water-based drilling fluids containing iron oxide (Fe2O3) and silica (SiO2) nanoparticles.

This paper focuses on experimental methods quantifying water-based muds and investigating effects on particle bridging, filtrate invasion, and permeability.
