Drilling fluid system name

Biological enzyme gel breaking system for horizontal wells

Matching core finishing agent

Clay stabilizer HCS    Biological enzyme breaker HSW    Water proof lock agent HAR / drag reducer HUL

System characteristics

1、Enzymatic hydrolysis;

2、The polymer macromolecule is degraded into maltose, glucose and other small molecules;

3、It can decrease the adhesion between the mud cake particles, while the mud cake loosens off;

4、It is environmental protection and safety, while it has good choice performance.

Application situation

The bio enzyme breaker has been successfully applied in Sultan oilfield.
