Laboratory data, including rheology and conductivity for fluids containing the new breakers, are compared to fluids containing traditional, low-temperature breakers. The release- rate profiles for the encapsulated breakers are discussed in relation to the pH...

... models, researchers originally treated the horizontal wellbore as being analogous to a vertical fracture having infinite or near infinite conductivity. Dikken1 was the first to demonstrate the potential limitations to production imposed by pressure drop across horizontal wells. That study initiated a...

.... With the evolution of the hybrid fracturing fluid total fluid volumes have been reduced, therefore minimizing proppant convection and increasing fracture conductivity, and reducing costs. The new fluid has allowed the proppant concentrations to be increased 3.3 fold, and proppant tonnage by 100...

The results have shown that the radius of investigation in such reservoirs starts increasing in the fracture network proportional to the square root of the fracture conductivity. When the matrix contribution to the flow of fluids starts the rate of advance of the radius decreases...
