摘要： The present invention relates to a dispersant polymer and a dispersion containing the dispersant polymer. The dispersant polymer is derived from a polyamine species reacted with two different polyester chains, one of which includes a monomeric repeat unit derived from the polyesterification reaction of lactide, glycolide, lactic acid, or glycolic acid monomers. The technology includes preparing the dispersant polymer at lower temperature to allow the use of a broader selection of polyester repeat units.

摘要： Methods and compositions for using lubricants in subterranean formations, and specifically lubricants that comprise certain oils, surfactants and solvents, and methods for their use, are provided. In one embodiment, the methods include introducing a treatment fluid that includes a base fluid and a lubricant including at least one vegetable oil, at least one nonionic surfactant, and at least one cosolvent into at least a portion of a subterranean formation.

摘要： The present invention relates to a dispersant derived from anhydride functionalized polyester derived from carboxylic acid functionalized polyester. The anhydride functionalized polyester is then reacted with a multi-amine species forming amide and salt bonds. The technology allows lower reaction temperatures when the multi-amine species is present. The lower reaction temperature allows the use of a broader selection of polyester repeat units.

摘要： A system and method for water shutoff, including providing a treatment fluid including a polymer and a nitrogen-generating compound through a wellbore into a water zone in a subterranean formation, generating nitrogen gas in the water zone by a reaction of the nitrogen-generating compound, generating foam from the nitrogen gas and the treatment fluid in the water zone to give foamed polymer in the water zone, and sealing the water zone with the foamed polymer.

摘要： A method for validating a homogenizing valve (1), comprising the steps of:—preparing an emulsion having a hydrophilic phase comprising, in weight percentage on the total weight: from 55% to 74% demineralized water, from 10% to 20% glycerin and from 3% to 4,2% butylene glycol, and a lipophilic phase comprising, in weight percentage on the total weight: from 5.1% to 5.9% squalane, from 7.2% to 8.8% caprylic acid alkyl ester and from 0.665% to 0.735% cetyl alcohol;—subjecting the emulsion to forced passage within the homogenizing valve (1) from a high pressure zone (HP) to a low pressure zone (LP) a plurality of times.

摘要： Wellbore fluids may include an oleaginous continuous phase; a non-oleaginous discontinuous phase; and a polymeric amidoamine emulsifier stabilizing the non-oleaginous discontinuous phase in the oleaginous continuous phase, wherein the polymeric amidoamine emulsifier has at least 5 repeating units. Wellbore fluids may include an oleaginous continuous phase; a non-oleaginous discontinuous phase; and a polymeric amidoamine emulsifier stabilizing the non-oleaginous discontinuous phase in the oleaginous continuous phase, wherein the polymeric amidoamine emulsifier includes at least 3 repeating units selected from allylamine, polyaminopolyamide, N-alkyl acrylamides, (meth)acrylic acid, alkyleneamine reacted with a dicarboxylic acid, alpha-olefin-alt-maleic anhydride, styrene maleic anhydride, alkylene oxide, wherein one or more amine or acid group on the repeating unit is amidized.
