Abstract

En el trabajo de estimulación, particularmente en los trabajos de fracturación o acidulación, de pozos de hidrocarburos que tienen perforaciones que conducen a las formaciones portadoras de los hidrocarburos, se emplea un fluido que incluye una fase continua de un compuesto de fórmula (1) o que incluye dicho compuesto de fórmula (1): (R2)p-Ph-(CH2)m-COO-(AO)n-R1 en donde: R1 es un grupo hidrocarbilo C1-20; AO es un grupo alquilenoxi y puede variar a lo largo de la cadena (poli)alquilenoxi; n es 0 o es de 1 a 100; m es 0, 1 o 2; y Ph es un grupo fenilo que puede estar sustituido con grupos (R2)p en donde cada R2 es independientemente un grupo alquilo C1-4 o alcoxi y p es 0, 1 o 2, particularmente, los ésteres son ésteres de benzoato de alquilo o alquenilo. Estos ésteres resultan beneficiosos al disponer de una gama de viscosidades, cuya gama se extiende especialmente hasta viscosidades bajas, así como perfiles toxicológicos y medioambientales atractivos para utilizarse en los trabajos de estimulación de pozos.In the stimulation work, particularly in fracturing or acidification work, of hydrocarbon wells that have perforations that lead to the hydrocarbon-bearing formations, a fluid is used that includes a continuous phase of a compound of formula (1) or which includes said compound of formula (1): (R2) p-Ph- (CH2) m-COO- (AO) n-R1 wherein: R1 is a C1-20 hydrocarbyl group; AO is an alkyleneoxy group and may vary along the (poly) alkyleneoxy chain; n is 0 or is 1 to 100; m is 0, 1 or 2; and Ph is a phenyl group that can be substituted with groups (R2) p wherein each R2 is independently a C1-4 alkyl or alkoxy group and p is 0, 1 or 2, particularly, the esters are esters of alkyl or alkenyl benzoate . These esters are beneficial to have a range of viscosities, whose range extends especially to low viscosities, as well as toxicological and environmental profiles attractive for use in well stimulation work.
