Effect of Water Distribution on Spontaneous Imbibition of Tight Rocks: A Fractal Approach
Energies, 2020 The original water distribution characteristic plays an important role in the fracturing liquid retention in actual tight reservoirs. In this paper, an analytical model was proposed to characterize the water distribution and its effect on the spontaneous

A Generalized Capillary Imbibition Model for Porous Media in Tight Reservoirs
Advances in Civil Engineering, 2018 Capillary imbibition models have been widely studied in oil and gas development field over the past decades. However, the existing models applied to the tight reservoirs rarely take fluid flow resistance and apparent viscosity into account.
