摘要:
A solvent system for use in acidizing and cleanup in oil wells and gas wells. The solvent system comprises a substantially water-soluble alcohol, such as methanol, or ethanol or any mixture thereof, a substantially water/oil-soluble ester, such as one or more C.sub.2-esters through C.sub.10-esters and a substantially water/oil-soluble ketone, such as one or more C.sub.2-ketones through C.sub.10-ketones.
摘要:
An apparatus and method for the treatment of stimulation fluid that involves passing a mixture of the stimulation fluid and reagents through a sectioned tank, each section having the means to agitate the mixture contained therein. Treated fluid is removed from a final settling section for reuse in oil and gas production operations.
摘要:
An alcohol acidizing system for use in acidizing and cleanup in oil wells and gas wells. The system comprises an aqueous acid, such as hydrochloric acid, and at least one of an alkyl alcohol, such as methanol, ethyl alcohol, iso-propanol or the like, or any mixture thereof, an acetylenic alcohol such as methyl butynol, methyl pentynol, hexynol, ethyl octynol, propargyl alcohol, benzylbutynol, ethynylcyclohexanol, or the like, and an acetylenic diol, such as an alkoxylated acetylenic diol. The system may also contain water.
