Name : Petrolize® CL
Description : Cellulase Carbohydrase Enzyme system to break down Filter-Cake formed by PAC or Cellulose based mud systems.
Enzymatic Mud Breaker for Cellulose Based Mud
To efficiently hydrolize Cellulosic component used in the clean Drill-in fluid, Epygen developed PETROLIZE CL, a medium to high temperature stable Cellulase (Endo-glucanase and Cellobiohydrolase) which, depending on the well temperature and pH will break down PAC component or, cellulosic biopolymer of the mud damage into simple sugars within 1 to 10 hours (proposed 5 hours shut in period) time, breaking down the integrity of the filter-cake evenly, allowing the bridging agent to disperse efficiently and cleanly.
Usage levels of PETROLIZE CL will depend on nature of clean up fluid, pH, downhole temperature and bio-polymer mix, between 5 to 20 Liters per 1000 Liters of Clean-up fluid.
