Abstract
Swellable spacer fluids can be useful in subterranean operations for sealing an annular space in a well bore, such as the annular space between a tubular and the subterranean formation or between two concentric tubulars, or for forming a seal inside a well bore in the subterranean formation. One embodiment of such methods involves providing a swellable fluid, wherein the swellable fluid comprises: an aqueous fluid, a crosslinking agent, and at least a plurality of swellable particles; and placing the swellable fluid in a subterranean formation, and allowing the spacer fluid to form a semi-solid crosslinked gel structure in the subterranean formation.
