Purpose

HimLube RG is used in oil and gas industry during the construction of wells to control filtration and stabilize the walls of the well. The chemical product is graphite particles that are able to shrink and restore their shape without destruction. When the pressure in the well increases, the particles compress and penetrate into cracks and pores, sealing the rock. The formed block isolates the rock from the tool, which helps to reduce tool wear, transfer the load to the drilling bit, facilitate rotation and provide lowering the casing of high quality. HimLube RG reduces HTHP filtration, is chemically inert and compatible with water-based and oil-based fluids.

Recommendations to application

The recommended concentration of HimLube RG for the initial treatment of drilling fluid: to reduce friction – 5-10 kg/m3 , to reduce filtration losses – 15-50 kg/m3 , combined with HimSeal fine latex consolidator it enhances the effect of the reagent. In areas of intense absorption, compositions with a reagent concentration of up to 200 kg/m3 are used in combination with other components to eliminate absorption of various volume.
