Method of using viscosified fracture fluid to improve flow of liquids and gases from a subterranean fracture |
| abstract |
A method of improving flow of liquids and gases from a subterranean fracture using a viscosified fracture fluid 1 formed by combining a solid proppant, a binding agent and an enzyme to form a proppant-immobilized enzyme 2 , mixing the proppant-immobilized enzyme 2 with a second proppant 3 to form a heterogeneous proppant pack 4 and mixing said heterogeneous proppant pack 4 with a gelled liquid fracturing fluid 5 to form the viscosified fracture fluid 1 containing the heterogeneous proppant pack 4 . The viscosified fracture fluid 1 containing the heterogeneous proppant pack 4 is pumped 6 into a subterranean zone 7 to form one or more fractures therein. The proppant-immobilized enzyme 2 that is part of the heterogeneous proppant pack 4 has the dual purpose of propping open the subterranean fractures and reducing the viscosity of the viscosified fracture fluid. |
