ABSTRACT:
An almond shell additive for a well working fluid is provided, wherein the almond shells are ground to certain particle size ranges to prevent, inhibit or remedy the occurrence of downhole equipment sticking. Also provided are wellworking fluids containing the almond shell additive and well working processes utilizing such compositions. The additive is also useful to reduce wall cake thickness and permeability, enhance well cake toughness, seal off depleted sands and micro fractures, reduce or prevent seepage loss, control dynamic spurt loss, and reduces drag and torque.
