A method of treating a portion of a well comprising: introducing the treatment fluid into the well; and causing or allowing at least a portion of the degradable matrix to degrade, wherein degradation of the degradable matrix releases at least some of the additive into the wellbore fluid.

Delayed-release additives in a degradable matrix

A fluid comprising: an aqueous phase; a cellulose derivative dispersed or dissolved in the aqueous phase; a guar derivative dispersed or dissolved in the aqueous phase; a titanium crosslinker dispersed or dissolved in the aqueous phase; and a zirconium crosslinker dispersed or dissolved in the aqueous phase. A method of treating a well or a well system can include: (A) forming a treatment fluid according to the disclosure; and (B) introducing the treatment fluid into a treatment zone of a well.

Polysaccharides and metal complexes for viscosity

A method of treating a subterranean formation includes providing capsules comprising at least one of a mineral acid, a Lewis acid, a hydrolysable acid precursor, and mixtures thereof; providing a carrier fluid; placing the capsules and the carrier fluid into a zone in a shale formation, the zone comprising fractures; allowing the capsules to at least partially dissolve. Upon the hydrolysis of the acid, etching of the faces of the fractures occurs.

Methods for increasing the surface area of fractures or to increase the depth of penetration fractures in low permeability oil and gas reservoirs containing shale to increase productivity

A method is provided for improved degradation of metal-crosslinked polymer gels, which are useful in oil and gas treating operations. In this method a polysaccharide having a higher degree of substitution than the polymer in the polymer gel is added to the gel. The polysaccharide removes the crosslinking metal ion from the gel to thus break down the gel and reduce its viscosity.
