Abstract
A system and method for cavitating a producible formation is disclosed. The method include conglomerating the formation, producing the formation above its critical draw down pressure resulting in cavitation of the formation and producing the cavitated formation below a higher maximum sand free rate (MSFR).
Claims (12)
1. A method comprising:
injecting an effective amount of an aggregating, agglomerating, or conglomerating composition into a weakly consolidated, semi-consolidated or unconsolidated formation or a zone thereof, where the effective amount of the aggregating, agglomerating, or conglomerating composition is sufficient to reduce or prevent formation cave in or collapse, when the formation or zone is produced above its critical draw down pressure, producing the conglomerated formation above its critical draw down pressure, until a desired volume of formation particulate co-production is produced to form a cavitated formation or zone, and producing the cavitated formation or zone below its new critical draw down pressure, where the cavitation comprises a cavity or void space between the casing, liner, production tubing or equipment and the formation and the cavitation increases a MSFR.
injecting an effective amount of an aggregating, agglomerating, or conglomerating composition into a weakly consolidated, semi-consolidated or unconsolidated formation or a zone thereof, where the effective amount of the aggregating, agglomerating, or conglomerating composition is sufficient to reduce or prevent formation cave in or collapse, when the formation or zone is produced above its critical draw down pressure, producing the conglomerated formation above its critical draw down pressure, until a desired volume of formation particulate co-production is produced to form a cavitated formation or zone, and producing the cavitated formation or zone below its new critical draw down pressure, where the cavitation comprises a cavity or void space between the casing, liner, production tubing or equipment and the formation and the cavitation increases a MSFR.
2. The method of claim 1, wherein the aggregating, agglomerating, or conglomerating composition comprises a reaction product of an amine and a phosphate ester, at least an acidifying agent and a surface modifying agent, or a mixture or combination thereof.
3. The method of claim 1, further comprising:
prior to the second producing step, injecting an effective amount of a second aggregating, agglomerating, or conglomerating composition into the cavitated formation or a zone thereof, wherein the effective amount of the second aggregating, agglomerating, or conglomerating composition is sufficient to further conglomerate the formation or zone.
prior to the second producing step, injecting an effective amount of a second aggregating, agglomerating, or conglomerating composition into the cavitated formation or a zone thereof, wherein the effective amount of the second aggregating, agglomerating, or conglomerating composition is sufficient to further conglomerate the formation or zone.
4. The method of claim 3, wherein the aggregating, agglomerating, or conglomerating compositions are the same or different and comprise a reaction product of an amine and a phosphate ester, at least an acidifying agent and a surface modifying agent or a mixture or combination thereof.
5. The method of claim 1, further comprising:
prior to the second producing step, injecting an effective amount of a consolidating composition into the cavitated formation or a zone thereof, wherein the effective amount of the consolidating composition is sufficient to consolidate the formation or zone.
prior to the second producing step, injecting an effective amount of a consolidating composition into the cavitated formation or a zone thereof, wherein the effective amount of the consolidating composition is sufficient to consolidate the formation or zone.
[007016. The method of claim 5, wherein the aggregating, agglomerating, or conglomerating composition comprises a reaction product of an amine and a phosphate ester at least an acidifying agent and a surface modifying agent or a mixture or combination thereof.
