Organophilic Bentonite Clay as a Rheological Additive for High-Temperature Drilling Fluids

In the field of oil drilling, the high temperature and high pressure environment to realize the completion operation, for the drilling fluid requirements are very high, and at the same time the performance of the completion fluid also directly affects the drilling productivity.

Therefore, we apply organic bentonite to well completion fluids and drilling fluids. Improving its productivity and realizing its rheological properties and suspension is what we have been trying to do.

Our organobentonite formulations are carefully configured to maintain their full chemical effect and performance at elevated temperatures and pressures in excess of 180°C. The formulation of organobentonite can be utilized in a variety of fluids, such as drilling fluids and completion fluids.

Its stability and ability to carry solids in reverse emulsion fluids makes it a direct choice for high temperature, high pressure completions. If we want to improve the thermal stability and plugging ability, as well as enhance its rheological properties.

We should consider carefully determining the steps we take to incorporate organobentonite into our completion fluids. Because the wrong order of addition can affect the performance of the organobentonite itself.

The successive interactions of the organoclay with the reverse emulsion. It increases the viscosity and yield stress of the fluid, which realizes its suspension properties.

It acts as an accelerant in the suspension which ensures. The fluid column remains stable, prevents inflow of formation fluids, and maintains the integrity of the wellbore
