Materials to combat acquisitions
FIBREX
Fibrous materials
Calcium carbonate with a fractional composition of from 5 to 400 microns. Calcium carbonate is an integral component of all water-based drilling fluids, as its main functions are the formation of a filtration crust and clogging of the pores of permeable rocks. Another function of calcium carbonate is to significantly increase the density of the drilling fluid when necessary.
SHELLMIX
Polydisperse materials
Purified barite concentrate or barite having an absolute density of 4.2 kg / m3. Barite is a universal and completely inert weighting agent, allowing to increase the density of drilling fluids to values over 2 kg / m3, depending on the nature and type of solution.
RESIMIX
Polydisperse materials
Modified asphaltene, significantly improving the quality of the filtration crust and reducing filtration rates at high temperatures. The reagent also has an inhibitory effect, slowing down the hydration of active clays and unstable rocks in the environment of water-based drilling fluids.
