PREPARATION OF HYDROCARBON GELS FROM FERRIC SOURCES, POLYCARBOXYLIC ACID COMPOUNDS, AND OPTIONAL AMINES, IN COMBINATION WITH PHOSPHATE ESTERS |
摘要 |
<p>This invention relates to improved hydrocarbon gels which find use in the fracturing of petroleum producing formations. In particular it relates to the use of a define class of gelling agents for hydrocarbons which provide excellent results in such fracturing. The gelling agents comprise combinations of (1) selected orthophosphate esters and (2) a composition comprising a source of ferric ions, an amine, and a polycarboxylic acid or salt thereof.</p> |
