Fluid-Loss Control Agent

■ High Efficiency Fluid-Loss Control Agent for Water-based Mud (SRD-191)
■ OBM High Temperature Fluid-Loss Control Agent (SOM-03) up to 430℉ (220℃)
■ High Temperature Acid Soluble Fluid Loss Additive for Water-Based Mud (SRD-06)

Sealing Agent Nano-polyester

Sealing Agent (SRD-65) is a field proven additive that allows building a low invasion drilling fluid which improves wellbore circumferential stress, prevents hole collapse and effectively controls mud losses.

Lubricant for Drilling Fluid

Low-fluorescence Drilling Fluid Lubricant (SRD-LB) forms a solid chemical film on the metal surface, effectively reduce the friction resistance of the metal contact surface, reduce the wear of drilling tools and other metal parts.

Super Sweeping Fiber

Super Sweeping Agent (CQY-7) is a special treated 100% virgin synthetic monofilament fiber that is used as a hole cleaning agent.
