HimSeal — Himprom

Purpose

HimSeal is designed to stabilize the wellbore. Elastic and deformable reagent particles make it possible to effectively seal microcracks and pores. The use of HimSeal contributes to the formation of thin, dense, elastic filter cake and prevent the sloughing of unstable clay rocks. HimSeal provides additional control of filtration HTHP, high efficiency in reducing filtration PPT and minimizes the occurrence of differential sticking.

Recommendations to application

For maximum efficiency and the creation of a low-permeable filtration cake, HimSeal is recommended to be used together with a cross-linking agent, for example, chalk. The optimal concentration depends on the formation geology and the presence of additional microcolmatants in the composition of the solution. It is recommended to conduct preliminary test to estimate the effect on the system properties, the preferred starting concentration is from 20 kg /m3 .
