Abstract
A system and method for cavitating a producible formation is disclosed to improve hydrocarbon production and to increase a production rate without an concurrent co-production of formation particulate. The method and system include conglomerating the producible formation using a conglomerating composition. Once the producible formation is conglomerated, the conglomerated, producible formation is produced above its critical draw down pressure to form a cavity surrounding the wellborn in the conglomerated, producible formation and placing the cavitated, conglomerated, producible formation on production below a higher maximum sand free rate (MSFR).
Claims21
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 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 higher maximum sand free production rate (MSFR).
A method comprising:
- injecting an effective amount of a first 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,
- 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, and
- producing the cavitated formation or zone below its 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 higher maximum sand free production rate (MSFR).
