Abstract
A method for reducing lost circulation in a subterranean formation. The method includes providing a treatment fluid comprising a base fluid and a lost circulation material comprising cane ash. The treatment fluid is introduced into a wellbore within the subterranean formation such that at least a portion of the cane ash bridges openings in the subterranean formation to reduce loss of fluid circulation into the subterranean formation.
Claims20
A method for reducing lost circulation in a subterranean formation, the method comprising:
- providing a treatment fluid, wherein the treatment fluid is a cement composition comprising a cement, water, and a lost circulation material comprising cane ash;
- introducing the treatment fluid into a wellbore within the subterranean formation such that at least a portion of the cane ash bridges openings in the subterranean formation to reduce loss of fluid circulation into the subterranean formation;
- and
- allowing the treatment fluid to set in the wellbore.
A treatment fluid comprising:
- a cement composition comprising:
- a cement,
- water, and
- a lost circulation material comprising cane ash, wherein the cane ash comprises at least 70% quartz.
A system for bridging a lost circulation zone comprising:
- a treatment fluid, wherein the treatment fluid is a cement composition comprising a cement, water, and a lost circulation material comprising cane ash, wherein at least a portion of cane ash is in the form of fibers, wherein fibers are present in cane ash in an amount of about at least 5% by weight of cane ash with aspect ratio of about at least 1;
- a fluid handling system comprising the treatment fluid;
- and
- a conduit at least partially disposed within the wellbore and fluidically coupled to the fluid handling system.
