Drilling/completion fluids
This paper evaluates the effect of rapid cooling on the rock-cutting process and incorporates this effect as a component of drilling-performance optimization.
Advancements in new technologies and rigorous testing methods have enabled the authors of the three SPE papers featured this year to outline a path forward, offering new possibilities that uphold the core objectives of safety and productivity.
This paper highlights a new online system for monitoring drilling fluids, enabling intelligent control of drilling-fluid performance.

This paper describes the first application of clay-free IEFs in the Norwegian continental shelf (NCS), with an emphasis on an impressively low and consistent ECD contribution. -
This paper describes the evaluation of a nanofluid containing nanomaterials with high adsorption capacity used for asphaltene inhibition in the volatile Cupiagua Sur oil field in Colombia.

Historically, invert-emulsion drilling fluids are the preferred system for drilling offshore Cameroon. However, with a regulatory environment moving toward zero discharge, associated costs are rising.
-
When oil-based mud is used, the drilled formation solids (cuttings) are regarded as controlled or hazardous waste.
-
A novel nonaqueous-fluid (NAF) system was designed to provide stable rheological properties with a nonprogressive gel structure and very good filtration control and filter-cake quality in wells where the expected bottomhole static temperature (BHST) exceeds 400°F.
-
A well in the South China Sea was diagnosed by ultrasonic and temperature logging to have a well-integrity problem, forcing the operator to shut in the well because the leak created a high tubing/casing-annulus pressure.
-
A novel solids-free fluid-loss pill for higher-temperature reservoirs has been formulated.
-
This year has been a great year for me; I was able to play more rounds of golf than expected! I was also successful in sealing a few research collaboration agreements within the oil and gas industry.

The Eagle Ford shale in Zavala County, Texas, is similar to many high-carbonate-content oil-shale formations.
