| Description | L'invention concerne un procédé qui peut consister à : introduire un fluide de traitement dans un puits de forage pénétrant dans une formation souterraine, le fluide de traitement comprenant un fluide de base ; un composé carbonate, le composé carbonate bouchant au moins partiellement une zone dans la formation souterraine ; et un acide ; et dévier au moins une partie du fluide de traitement et/ou un fluide introduit par la suite à l'opposé de la zone. |
| Abstract | A method may comprise: introducing a treatment fluid into a wellbore penetrating a subterranean formation wherein the treatment fluid comprises a base fluid; a carbonate compound, wherein the carbonate compound at least partially plugs a zone in the subterranean formation; and an acid; and diverting at least a portion of the treatment fluid and/or a subsequently introduced fluid away from the zone. |

| Claim | CLAIMS What is claimed is: A method comprising: introducing a treatment fluid into a wellbore penetrating a subterranean formation wherein the treatment fluid comprises: a base fluid; a carbonate compound, wherein the carbonate compound at least partially plugs a zone in the subterranean formation; and an acid; and diverting at least a portion of the treatment fluid and/or a subsequently introduced fluid away from the zone. The method of claim 1 wherein the carbonate compound comprises magnesium carbonate, calcium carbonate, or combinations thereof. The method of claim 1 wherein the acid is a solid acid with a solubility of less than about 5% by weight in water at 1 10 °F for one hour. The method of claim 1 wherein the acid comprises a solid acid selected from the group consisting of ethylenediaminetetraacetic acid, citric acid, formic acid, benzoic acid, and combinations thereof. The method of claim 1 wherein the treatment fluid further comprises a retarding agent comprising an oil-wetting surfactant, polymers coating the carbonate compound, or combinations thereof. The method of claim 1 wherein the treatment fluid further comprises a retarding agent selected from the group consisting of sodium dodecylbenzenesulfonate, emulsions of 2- ethylhexyl acrylate, and combinations thereof. The method of claim 6 wherein the retarding agent is present in an amount of about 0.1 % to about 5% by weight of the carbonate compound. The method of claim 1 further comprising introducing a fracturing fluid into the wellbore wherein the fracturing fluid comprises a proppant. The method of claim 8 wherein the treatment fluid is injected into the wellbore at or above a fracture gradient of the subterranean formation and the treatment fluid is intermittently injected into the wellbore while the fracturing fluid is injected into the wellbore. The method of claim ] wherein prior to the step of introducing, the treatment fluid is mixed in a mixer and thereafter injected using a pump. 1 1. A method of treating a subterranean formation, the method comprising: providing a treatment fluid comprising: a base fluid; and a solid state suspension comprising: a polymeric coating; a carbonate compound; and an acid; introducing the treatment fluid into a wellbore penetrating the subterranean formation, wherein the solid state suspension at least partially plugs a zone in the subterranean formation; and allowing the solid state suspension to dissolve. The method of claim 1 1 wherein the treatment fluid comprises a solid acid selected from the group consisting of ethylenediaminetetraacetic acid, citric acid, benzoic acid, and combinations thereof. The method of claim 1 1 wherein the treatment fluid further comprises a proppant. " The method of claim 1 1 wherein the step of pumping comprises pumping the treatment fluid into the subterranean formation at or above a fracture gradient of the subterranean formation. The method of claim 1 1 wherein the carbonate compound is present in an amount of about 30% to about 60% by weight of the solid state suspension. The method of claim 1 1 wherein the acid is present in an amount of about 40% to about 60% by weight of the solid state suspension, and wherein the polymeric coating comprises a dissolvable polymer. A treatment fluid comprising: a diverting agent comprising: a solid particulate; and a dissolvable coating. The treatment fluid of claim 17 wherein the solid particulate is selected from the group consisting of calcium carbonate, magnesium carbonate, group(I) salts, group (II) salts, sand and combinations thereof. The treatment fluid of claim 17 wherein the base fluid comprises water. The treatment fluid of claim 17 wherein the diverting agent further comprises a solid acid selected from the group consisting of ethylenediaminetetraacetic acid, citric acid, benzoic acid, and combinations thereof. The treatment fluid of claim 17 wherein the solid particulate is acid soluble and the treatment fluid further comprises an acid. The treatment fluid of claim 17 where solid particulate is incorporated into a polyvinyl alcohol in a solid state suspension. |
