Himbreak AB — Himprom

Purpose

Himbreak AB breaker is designed for use in the oil and gas industry to dissolve deposits of barium sulfate (barite) formed in the filtration cake during drilling. When cleaning the formation pay zone, the product converts barium sulfate BaSO4 into a soluble state, the size of barite particles reduces and they are removed from the pore space. As a result of the breaker operation the permeability of the reservoir increases and the flow of fluid is stimulated.

Recommendations to application

Himbreak AB breaker must be used in the form of an aqueous solution prepared using fresh water purified from calcium and magnesium ions. The concentration of the reagent is selected by model tests in accordance with the type and composition of the drilling mud used. The product is recommended to be used at reservoir temperatures from 90 °C. In order to increase the effectiveness of Himbreak AB, it is necessary to initially treat the formation pay zone with the Himbreak H for the primary removal of calcium carbonate CaCO3 scale.
