OCL-JA is a high temperature fluid loss control agent which contains Phenol, AMPS, AM and AA groups. It is an effective additive for reducing fluid loss at high temperature up to 450℉. OCL-JA is also effective as a deflocculant and inhibitor in all fresh water drilling fluid in deep wells. It can improve the rheological stabilization of drilling fluid.
With good inhibition it helps to stabilize water-sensitive shales and thereby prevent the well from collapsing.
Control fluid loss at temperature up to 450℉, can improve the filter-cake quality.
Evidences marked thinning ability.
Dosage ranges from 7-17.5ppb.
