摘要:
Well bores are drilled using an invertible oil external-water internal emulsion drilling fluid which is then inverted to a water external-oil internal emulsion by contacting it with an aqueous acid solution containing an anionic sulfonate surfactant for preventing aqueous acid solution-crude oil emulsions and crude oil sludging, and a chemical (eg an ethoxylated amine) for preventing the anionic sulfonate surfactant from rcacting with the emulsifier in the oil external-water internal emulsion.
摘要:
Stimulation, particularly fracturing or acidising, of hydrocarbon wells having bores leading to hydrocarbon bearing uses a fluid including a continuous phase of or including a compound of the formula (I): (R2)p-Ph-(CH2)m-COO-(AO)n-R1 where R1, AO, n, m, Ph, R2 and p have defined meanings and particularly where the esters are alkyl or alkenyl benzoate esters. These esters are beneficial by having a range of viscosities, especially extending to low viscosities, and attractive toxicological and environmental profiles for use in well stimulation.
摘要:
A hydrocarbon fracturing fluid for fracturing a subterranean formation containing a gelled liquid hydrocarbon made by adding a phosphonic acid ester having the formula: where R is an alkyl group having from 8 to 24 carbon atoms. A stoichiometric amount of a polyvalent metal source selected from ferric iron salts and aluminium compounds is also added. Water and an amount of a delayed gel breaker effective to break the gelled liquid hydrocarbon fracturing fluid is added to the hydrocarbon gelled liquid.
