TPASOL 18

A new type of water-soluble temporary plugging agent used in diverting fracturing. Its adjustable pressure, time and strength allows it to be tailored to control fluid flow in various porous formations. It has strong initial pressure deformation capacity (3 mm fracture width, bearing pressure above 50 MPa/m), good ductility, high tensile strength, good temperature, salt and shear resistance. TPASOL 18 can adhere strongly to the crack wall surface, is resistant to erosion, can be easily dissolved to form a simple liquid distribution and easily deployable to increase oilfield production.

Application

• Environmentally friendly – biodegradable into harmless CO2 and H2O
  
• Good compatibility with fracturing fluids and formation fluids
  
• Used in new well fracturing, repeated fracturing, sub-layer fracturing and casing
