Mud erosion in the subsea stratified sand-mud beds is a concern for production of methane gas from methane hydrate. It is expected that eroded mud may lead to well blockage. The goal of our work is to model of mud erosion that damages gas production. To approach this, we have developed a numerical simulation code and mud erosion is investigated to estimate model parameters. The water velocity in pore space is simulated by the Lattice Boltzmann Method (LBM). The paper shows the procedure to obtain erosion rate from distribution of shear stress on the mud surface.
