The method comprises adding bentonite to water to form a gel slurry and adding a cross linking agent to the gel slurry. The method further comprises adding a binding agent to the gel slurry and the cross linking agent and adding a strengthening agent to the binding agent, the gel slurry and the cross-linking agent. Further, the method comprises adding a bridging agent to the strengthening agent, the binding agent, the gel slurry and the cross linking agent. The method further comprises adding a retarder to the bridging agent, the strengthening agent, the binding agent, the gel slurry and the cross linking agent, where the loss control composition is a lightweight thixotropic composition that is prepared in a density range of 10 Pounds Per Gallon (ppg) to 16 ppg.
