Treatment of Oil Production Data under Fines Migration and Productivity Decline

Fines migration is a common cause of permeability and, consequently, injectivity and productivity decline in subterranean reservoirs. Many practitioners implement prevention or remediation strategies to reduce the impact fines on field injectivity. These efforts rely careful modelling underlying physical processes. Existing works have demonstrated ability predict by quantifying extent particle at different fluid velocities. Fluid flows porous media often involve multiple phases, which has been shown laboratory experiments influence detachment. However, no theory directly accounted for this detachment model. In work, new model fine detachment, expressed through critical retention function, presented, explicitly accounting immobile trapped within irreducible water phase. The utilises pore size distribution allow prediction Further, an analytical presented during radial flow into production well. accounts single-phase presence water, affect significantly. Combining these two models allows revealing effects connate saturation well impedance (skin factor growth) under migration. It that higher saturation, less effect appropriateness analyzing data verified successful matching 10 cases. study effective tool predicting rate skin growth, its stabilization time final value, as areal strained particles, allowing more intelligent design. findings can help better understanding how their might be influenced structure secondary
