Title
(EN) CLEANING COMPOSITIONS FOR OIL AND GAS WELLS, LINES, CASINGS, FORMATIONS AND EQUIPMENT AND METHODS OF USE
(FR) COMPOSITIONS DE NETTOYAGE POUR PUITS DE PETROLE ET DE GAZ, CONDUITES, TUBAGES, FORMATIONS OU EQUIPEMENTS, ET PROCEDES D'UTILISATION
Abstract
(EN)
The use of high flash point, low vapor pressure compositions for injection into, and coating of, gas and oil wells and surrounding underground hydrocarbon bearing formations and processing equipment for the purpose of removing scale, paraffins, tars, and other viscous constituents. Treatment results in increased flow of gas and/or oil and decreased adhesion of soils and scale in all aspects of oil and gas recovery, including hydrocarbon bearing formations, casings, lines, and pumping equipment. The composition contains about 40 to 99 wt.% of a fatty acid alkyl ester blend and about 1 to 25 wt.% of at least one lower alkyl glycol ether.
(FR)
L'invention concerne des compositions à points d'éclair élevés et à pression de vapeur réduite dont l'injection et le revêtement à l'intérieur de puits de gaz et de pétrole, de formations souterraines avoisinantes contenant des hydrocarbures et d'équipements d'exploitation permet d'éliminer le tartre, les paraffines, les goudrons et autres constituants visqueux. L'utilisation des compositions augmente le flux de gaz et/ou de pétrole et diminue l'adhérence des salissures et du tartre à tous les niveaux de l'extraction du pétrole et du gaz, y compris dans les formations qui contiennent des hydrocarbures, les tubages, les conduites, et le matériel de pompage. Les compositions renferment, en poids, environ 40 à 99 % d'un mélange d'acide gras et d'esters alcoyliques et environ 1 à 25 % au moins d'un éther glycolique d'alkyle inférieur.
