Abstract:
Methods and cement compositions are provided that utilize treated polyolefin fibers for lost circulation and/or mechanical property enhancement. Disclosed is a method comprising: providing a cement composition comprising: a hydraulic cement; water; and treated polyolefin fibers that are rod-shaped and have a length in a range from about 0.0625 inches to about 0.25 inches, wherein the treated polyolefin fibers have been treated with a surfactant to make the treated polyolefin fibers hydrophilic; placing the cement composition in a selected location; and allowing the cement composition to set.
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.
Abstract:
Disclosed are spacer fluids comprising cement kiln dust ("CKD") and methods of use in subterranean formations. An embodiment discloses a method comprising: providing a foamed spacer fluid comprising CKD, a foaming agent, a gas, and water; and introducing the foamed spacer fluid into a well bore to displace at least a portion of a first fluid present in the well bore. Another embodiment discloses a method comprising: providing a foamed spacer fluid comprising a partially calcined kiln feed removed from a gas stream, a foaming agent, a gas, and water, wherein the partially calcined kiln feed comprises SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, MgO, SO 3 , Na 2 O, and K 2 O; and introducing the foamed spacer fluid into a well bore to displace at least a portion of a first fluid present in the well bore.
