Detailed Description
Detailed introduction to RUN Active Anti-swelling Agent:
Run active anti-swelling agent is a new technology product first produced in the world by Suncoo Petrolume Technology Co.,Ltd . Its main ingredient is active inorganic semiconduit& can be widely applied to reservoirs with mudstone repair process and& recovery efficiency improvement process. Compared with other anti-swelling agent, it consider about water damage problem especially for reservoir with mudstone and low permeability reservoirs .Therefore, the product with active material added can eliminate water it is a new multi-functional reservoir minerals processing products, developped from brand new visual angle.&
