We based on both physical modeling and theoretical substantiation, the following facts were established: – a total residual saturation and residual water and LPP saturations have parabolic relationship from initial water and LPP saturations for draining a LPP-water system; – during natural water table raise LPP (kerosene) moves no higher than 10 cm and trapped in a capillary zone; – during initial and following water table lowering after mobile LPP layer accumulation, residual LPP content is different and methods for its determination are described. |
