摘要

Methods of fracturing a formation part of a subterru00e1nea, compaction and fracturing of a formation subterru00e1nea and reduce a surface pressure necessary to create one or more fractures in a part of a formation subterru00e1nea this invention concerns methods p For the treatment of underground formations.In a form of realization, the present invention provides a method of fracturing a portion of a subterranean formation comprising providing a treatment fluid comprising an aqueous fluid viscous salt only having a density greater than 9 pounds per gallon (1.08 kg / L) and 47. You viscosificador cross-linked.And the contact part of the underground formation with a treatment fluid viscous so as to create or enhance one or more fractures in this particular case, in which the fluid is introduced in a viscous processing hole which penetrates in the shaft part of the underground formation to be fractured in a Surface pressure of less than about 25000 pounds per square inch (172,4 MPa).In other forms of realization, the present invention provides methods of fracturing a subterranean formation and compaction and methods to reduce a surface pressure necessary to create one or more fractures in a portion of a subterranean formation.
