The Characteristics of Oil Migration due to Water Imbibition in Tight Oil Reservoirs

Energies, 2019
In tight oil reservoirs, water imbibition is the key mechanism to improve oil production during shut-in operations. However, the complex microstructure and composition of minerals complicate the interpretation of oil migration during water imbibition.

The Fractures Optimization Method with the Threshold Pressure of Multistage Fracturing in Tight Oil Reservoir

, 2017
As permeability of tight oil reservoir is generally less than 0.1md, diameters of pore throats are primarily at the micrometer- and nanometer-scale. Different from conventional reservoir, the percolation occurs mainly as non-linear flows so that the ...
