Product description

The product is made of surfactant, cation shale inhibitor and asphalt with certain range of softening point. It is manufactured with special technical process. The micron grade asphalt particulates with positive electricity tend to be adsorbed on solid grain with negative electricity. It helps the formation of slurry cake, improves slurry mud quality. I is possible that its micron grade cation shale inhibitor enters into well wall micro-joint, creating cohesion and mutual gathering, playing the role of blocking, bridging, expansion, swell, collapse control, water loss reduction and protection of oil-gas reservoir.
