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 red mud. The treatment fluid is introduced into a wellbore within the subterranean formation such that at least a portion of the red mud bridges openings in the subterranean formation to reduce loss of fluid circulation into the subterranean formation.
Claims5
A method for reducing lost circulation in a subterranean formation, the method comprising:
- providing a treatment fluid comprising a base fluid and a lost circulation material comprising red mud, wherein the red mud is derived from bauxite ore refining in the presence of sodium hydroxide, wherein 10% of the red mud comprises particle diameters less than 2.5 μm, wherein 10% of the red mud comprises particle diameters greater than 333 μm;
- and
- introducing the treatment fluid into a wellbore within the subterranean formation such that at least a portion of the red mud bridges openings in the subterranean formation to reduce loss of fluid circulation into the subterranean formation;
- wherein the treatment fluid is a cement composition or a spacer fluid, wherein the cement composition or the spacer fluid is disposed within a lost circulation zone.
A system for bridging a lost circulation zone comprising:
- a treatment fluid comprising red mud and a base fluid wherein the red mud is derived from bauxite ore refining in the presence of sodium hydroxide, wherein 10% of the red mud comprises particle diameters less than 2.5 μm, wherein 10% of the red mud comprises particle diameters greater than 333 μm;
- a fluid handling system comprising the treatment fluid;
- and
- a conduit at least partially disposed within the wellbore and fluidly coupled to the fluid handling system;
- wherein the treatment fluid is a cement composition or a spacer fluid, wherein the cement composition or the spacer fluid is disposed within a lost circulation zone.
