As we all know, petroleum directly or indirectly provides valuable resources for social development. THYLOCELL®HEC thickens, suspends, disperses, emulsifies, binds, forms film, and provides protective colloids. The role of oil drilling is also obvious to all. THYLOCELL® HEC has excellent salt tolerance, high viscosity, high shear rate, and reduced water loss, which can improve the stability of the wellbore, and make the uneven rock formation in a stable state. It improves the rock carrying capacity, limits the diffusion of drill cuttings, prevents damage to the production layer, and greatly increases the drilling speed and oil production. FORCA® Calcium Formate provides it with excellent early strength and completes oil cementing and well completion faster.
