摘要

THE USE OF HIGH FLASH POINT, LOW VAPOR PRESSURE COMPOSITIONS FOR INJECTION INTO, AND COATING OF, GAS AND OIL WELLS AND SURROUDING 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 EQUIPMENT. THE COMPOSITION CONTAINS ABOUT 40 TO 99 WTOF A FATTY ACID ALKYL ESTER BLEND AND ABOUT 1 TO 25 WTOF AT LEAST ONE LOWER ALKYL GLYCOL ETHER.
