... minerals are modeled, allowing for changes in rock and cement properties. Porosity is recalculated considering volume changes due to chemical reactions, and permeability is reevaluated using the Kozeny-Carman equation. Based on the simulation results, the chemo-mechanical composite layer model reassesses...

.... However, uncontrolled spurt and filtrate invasion are detrimental because they reduce the permeability of the formation. Mud composition, formation rock's permeability and porosity, and temperature can influence both spurt and filtrate invasion. The sizes of mud solids relative to the average pore size...
