Title (EN) THERMALLY STABLE SCALE INHIBITOR COMPOSITIONS
(FR) COMPOSITIONS ANTITARTRE THERMIQUEMENT STABLES
Abstract:
(EN) The present invention relates to a thermally stable polymeric scale inhibitor compositions and use thereof. Preferably, the polymeric scale inhibitor is a polycarboxylic acid copolymer comprising acrylic acid, methacrylic acid, and styrene sulfonic acid. The polymeric scale inhibitor compositions of the present invention are particularly suitable for high pressure/high temperature scale inhibition treatment of oil, gas, geothermal production wells and/or subterranean formations.
(FR) La présente invention concerne des compositions antitartre polymères thermiquement stables et leur utilisation. De préférence, l'antitartre polymère est un copolymère d'acide polycarboxylique comprenant de l'acide acrylique, de l'acide méthacrylique et de l'acide styrènesulfonique. Les compositions antitartre polymères de la présente invention sont particulièrement appropriées à un traitement antitartre à haute pression/haute température pour des puits de production de pétrole, de gaz, géothermique et/ou des formations souterraines.
