Abstract: A method comprising: introducing a first fluid into a wellbore above a fracture gradient of a subterranean formation penetrated by the wellbore to create a first plurality of fractures within a first portion of the subterranean formation; introducing a second fluid comprising at least one acid component into the wellbore above the fracture gradient of the subterranean formation penetrated by the wellbore to create a second plurality of fractures within a second portion of the subterranean formation; allowing the second fluid to enter at least one natural fracture in the first or second portion of the subterranean formation allowing the acid component to dissolve at least a portion of the subterranean formation to form one or more induced fractures in fluidic communication with the natural fracture, at least some of the first plurality of fractures, and at least some of the second plurality of fractures.

Abstract: Methods and systems for protecting acid-reactive surfaces, particularly during subterranean treatment operations in which acids are used. In some embodiments, the methods include: providing a fluid additive including an organic compound and a base, wherein the organic compound includes a phosphonoalkyl moiety; providing an acid or acid generating source; mixing at least the fluid additive and the acid or acid generating source to form a treatment fluid; and introducing the treatment fluid into at least a portion of a subterranean formation.

Abstract: A method of treating a subterranean formation penetrated by a wellbore, comprising introducing a chemical packer composition into the wellbore, wherein the chemical packer composition comprises water, a suspending agent, a gelling agent, and a sealant composition and wherein the chemical packer composition has a pH greater than 9, and allowing the chemical packer composition to form a plug, wherein a portion of the wellbore below the plug is isolated from fluid communication with a portion of the wellbore above the plug.

Abstract: Systems, compositions, and methods for reducing the production of water in subterranean formations having fractures or voids therein are provided. In one embodiment, the methods comprise: introducing a particulate material into a portion of a subterranean formation comprising one or more fractures or voids; and introducing a treatment fluid comprising a relative permeability modifier into the portion of the subterranean formation such that the permeability of the particulate material in the portion of the subterranean formation to water is reduced.
