TP-L4 is an organophilic lignite, designed to reduce high-pressure, high-temperature fluid loss of oil base drilling fluids. It can help to promote the emulsification of invert emulsion, and improve its stability, particularly in deep and hot wells.
TP-L4 is an amine treated lignite. It is low toxic. When carefully handling and operating, it will not cause problems to the operators’ health and to the environment. For more safety information, please refer to MSDS of TP-L4.
