Accomplishing the high miscibility of CO 2 and crude oil under reservoir conditions is critical
for achieving the most efficient recovery process by CO 2 injection into low-porosity and low …

CO 2 miscible flooding is a prospective production method to enhance oil recovery (EOR),
especially in low-permeability reservoirs. However, there is a lack of comprehensive and …

In view of the unsatisfactory improvement effect of pure CO 2 injection on the shale oil
recovery in microscopic pores, the molecular dynamics method was used to simulate the …

With the increasing demand for petroleum, shale oil with considerable reserves has become
an important part of global oil resources. The shale oil reservoir has a large number of …

Sequestering CO 2 in oil reservoirs using CO 2 huff-n-puff technology while maximizing oil
recovery is critical for the efficient development of shale/tight reservoirs. In this work, intrinsic …

Imbibition and huff-n-puff injection in shale reservoirs can significantly enhance oil recovery
after depletion. To clarify the microscopic production characteristics and enhance the oil …

The conversion coefficient C between relaxation time T2 value and pore size was calibrated
by a high-pressure mercury injection experiment, low-temperature nitrogen adsorption …

Gas huff and puff (HnP) is one of the means to improve shale oil recovery, and the
commonly used gases are CO2 and N2. However, the current research on CO2 and N2 HnP …
