Abstract
Methods for treating an earthen formation may include: drilling at least a section of a wellbore using a first wellbore fluid containing a first base fluid, and a first LCM-forming component; injecting, upon experience of a fluid loss, a second wellbore fluid containing a second base fluid, and a second LCM-forming component; and reacting the first LCM-forming component with the second LCM-forming component to form an LCM that reduces the fluid loss. A fluid system may include a first component containing a first base fluid and a first LCM-forming component; and a second component containing a second base fluid and a second LCM-forming component, wherein the second LCM-forming component is capable of reacting with the first LCM-forming component to form a LCM.
