<p>A downhole sealant includes a composition that includes a polymer; an absorbent material; a primary crosslink network including primary bonds between chains of the polymer; and a secondary crosslink network which is transient. A method of regulating the swell rate of the downhole sealant includes disposing a downhole sealant comprising a polymer and an absorbent material in a borehole; maintaining a primary crosslink network of the polymer; and decomposing a secondary crosslink network of the absorbent material in response to a condition to regulate the swell rate of the downhole sealant.</p> |
