MEGADRIL Oil-Base Drilling Fluid System

Overview Library

Durable, temperature-stable invert emulsion fluid without higher gel strengths

The MEGADRIL drilling fluid system delivers robust, temperature-stable invert emulsion fluid without the associated elevated gel strengths. Through its unique combination of chemistries, the MEGADRIL system produces an improved relationship among the 6 RPM reading, gel strength, and yield point.

Increased hole-cleaning capabilities

The MEGADRIL system results controls filtration without increasing overall viscosity. It has a higher tolerance for drill solids that can cause progressive gel strengths, allowing for reduced pump pressures and increased hole-cleaning capabilities while retaining manageable equivalent circulating density (ECD) values.

Superior cuttings transportation and fewer packoffs

The MEGADRIL system’s relationship among the yield point, 6 RPM dial reading, and the gel structure allows for superior cuttings transport, dramatically improving hole cleaning. The system’s constant rheological relationship ensures efficient cuttings transport and fewer packoffs.
