This invention relates to reduced volatility gelled liquid hydrocarbon treatment fluids and methods of their use and preparation. In one embodiment, this invention provides a method of treating a portion of a subterranean formation comprising: providing a reduced volatility gelled liquid hydrocarbon treatment fluid that comprises a liquid hydrocarbon and a gelling agent that comprises a polyvalent metal salt of a phosphoric acid ester, and treating the portion of the subterranean formation with the reduced volatility gelled liquid hydrocarbon treatment fluid. In another embodiment, this invention provides a gelled liquid hydrocarbon treatment fluid: that comprises a liquid hydrocarbon and a gelling agent that comprises a polyvalent metal salt of a phosphoric acid ester; that has a concentration of less than about 250 mg/liter of trialkyl phosphate esters that have a molecular weight of less than about 350; and that has a diester-to-monoester content molar ratio of at least about 2:1.

L'invention concerne des fluides de traitement à base d'hydrocarbures en liquide gélifié de volatilité réduite ainsi que des méthodes pour les utiliser et les préparer. Dans l'une des applications, l'invention fournit une méthode pour traiter une formation souterraine, consistant à fournir un fluide de traitement à base d'hydrocarbures en liquide gélifié de volatilité réduite composé d'un hydrocarbure liquide et d'un agent gélifiant qui renferme un sel métallique polyvalent d'un ester d'acide phosphorique, et à traiter la portion de la formation souterraine avec le fluide de traitement à base d'hydrocarbures en liquide gélifié de volatilité réduite. Dans une autre application, l'invention fournit un fluide de traitement à base d'hydrocarbures en liquide gélifié de volatilité réduite composé d'un hydrocarbure liquide et d'un agent gélifiant qui renferme un sel métallique polyvalent d'un ester d'acide phosphorique, ayant une concentration de moins de 250 mg/litre d'esters de trialkylphosphate de masse moléculaire inférieure à environ 350, dont le ratio molaire de diesters aux monoesters est d'au moins environ 2:1.
