    Abstract: A method includes positioning at least one fluid nozzle disposed upon a distal end of a fluid conduit in a cased borehole penetrating a subterranean formation at a target zone of the subterranean formation. An abrasive laden fluid is then continuously pumped through the fluid conduit and through the at least one fluid nozzle at a pressure adequate to form at least one slot through the cased borehole. The abrasive fluid contains an aqueous medium, an abrasive, an optional acid, and a viscoelastic surfactant. While continuously pumping the abrasive fluid through the fluid conduit, the wellbore may be cleaned by returning debris and material generated in the operation to the surface with the fluid. In some instances, a portion of the forming a slot through the cased borehole is conducted simultaneous with the cleanout of the wellbore.

    Abstract: Methods of treating a subterranean formation are disclosed that include introducing a treatment fluid including thermally shrinkable fibers and a particulate material into a subterranean formation via a wellbore, adjusting at least one parameter of the treatment fluid to trigger the association of the thermally shrinkable fibers, and forming a porous pack including a network of shrunken fibers by applying heat sufficient to raise the temperature of the thermally shrinkable fibers to a temperature at or above a shrinking initiation temperature of the thermally shrinkable fibers.

    Abstract: In a method of treating a sandstone-containing formation penetrated by a wellbore, a treatment fluid comprising an aqueous fluid containing a Bronsted acid, a hydrogen fluoride source and an organic acid or salt thereof that is substantially soluble in the aqueous fluid is formed. The treatment fluid contains less than about 2% of fluoride (F−) by weight of the fluid and from 2% or less of sodium (Na+) by weight of the fluid. The treatment fluid is introduced into the formation through the wellbore as a single-stage without introducing an acid-containing fluid preflush into the formation prior to introducing the treatment fluid.

    Abstract: Fluids containing surfactants and hydrophobic particles are effective media for cleaning non-aqueous fluids (NAFs) out of a subterranean wellbore. The fibers and surfactants are preferably added to a drilling fluid, a spacer fluid, a chemical wash, a cement slurry or combinations thereof. NAFs, such as an oil-base mud or a water-in-oil emulsion mud, are attracted to the fibers as the treatment fluid circulates in the wellbore.
