ZOC-LET GR is the basic system of ZOC-LET system. It is composed of natural glass beads ZOC-P61 as weight lighting agent, ZOC-BT1/ZOC-BT4 as enhancer and other additives as auxiliary materials. ZOC-LET GR is suitable for cementing operation of low-pressure leakage well, long sealing section and under-balance drilling.
