Overview
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 semiconductor superfine grain;it 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 damage effectively ; it is a new multi-functional reservoir minerals processing products, developped from brand new visual angle.

Features
Ø The anti-swelling function for channel of swelling clay mineral is double , wash oil function included;
Ø Formation wetted and cleaned, water lock damage eliminated, injection pressure reduced , oil well penetration improved.
Ø The clay suspension particle size become smaller.
Ø Good compatibility with formation water, fresh water
Ø Good compatibility with acidizing liquid , fracturing fluid, surfactant and inorganic salt ;it can be used as preflush of acidification and fracturing process, which produces good synergistic effect.
Applications
Products can be widely used in sensitive reservoir repair processing. Wells acidification,Blocking removal, sand control ,fracturing , oil well washing, all can be applied to. Usage is 0.5% - 3%; recommended usage is 2.5% to 3%. Solid RUN - 1 is used in acidization and blocking removal; liquid RUN - 2 is used in fracturing preflush.
