A method of treating a well or a subterranean formation with an aqueous treatment fluid containing one or more oil-soluble, water-insoluble well treatment agents. The fluid includes an aqueous dispersion containing the well treatment agent in an amount from 25 to 60 weight percent. The volume average particle diameter of the oil-soluble well treatment agent in the fluid may be less than or equal to 2.5 microns. The fluid may further contain a water-soluble well treatment agent.

Treatment methods using aqueous fluids containing oil-soluble treatment agents

Sandstone formations of oil and gas and geothermal wells may be successfully stimulated with a fluid containing GLDA or salt and HF or a HF-generating component and an organophosphonate component. The organophosphonate acts as a sequestering agent and reduces the amount of metal fluoride precipitates produced.

Use of sequestering agent in GLDA-based treatments for siliceous formations

The rate of release of a well treatment agent into a well may be controlled by introducing into the well a screen containing a well treatment composite having a well treatment agent and a support for the well treatment agent. The diameter of the substrate is less than the diameter of the opening of the screen of the screen assembly. Over time, the well treatment agent is released from the substrate and passes from the interior of the screen into the well.

Method of using a screen containing a composite for release of well treatment agent into a well

The flow of a stimulation fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of an acid soluble or acid degradable solid particulate and a composite of an acid or an acid generating compound adsorbed onto a water-insoluble adsorbent. Conductive flow of hydrocarbons from an occluded fracture may be resumed by release of the acid from the adsorbent or the acid generating compound.

Use of an acid soluble or degradable solid particulate and an acid liberating or acid generating composite in the stimulation of a subterranean formation

A well servicing fluid formulated with ingredients comprising a viscosifying polymer that is a crosslinked copolymer of an ethylenically unsaturated dicarboxylic anhydride and an alkyl vinyl ether, or the di-acid thereof; a pH adjuster capable of maintaining a pH of 5.5 or greater; and a solvent. Methods of treating a well formation with the wellbore servicing fluid and methods of making the wellbore servicing fluid.

The flow of a fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of a diverter having the structural formula (I):  Anhydrides of formula (I) are also acceptable as the diverter.

Method of using phthalic and terephthalic acids and derivatives thereof in well treatment operations

A thermothickening composition includes a surfactant; and a thermothickening polymer that is the product of at least the following monomers: a non-ionic hydrosoluble unsaturated amide monomer; an ionic monomer; and an unsaturated dicarboxylic acid half ester having a heat sensitive functional group.
