Moghadasi et alios [10] evaluated Corey, Chierici and LET correlations for oil/water relative permeability using a sophisticated method that takes into account the number of uncertain model parameters. They found that LET, with the largest number (three) of uncertain parameters, was clearly the best one for both oil and water relative permeability.
Craig [1] proposed three rules of thumb for interpretation of wettability from relative permeability curves. These rules are based on the value of interstitial water saturation, the water saturation at the crossover point of relative permeability curves (i.e., where relative permeabilities are equal to each other), and the normalized water permeability at residual oil saturation (i.e ...
Special core analysis is distinguished from "routine (RCAL) or conventional (CCAL) core analysis" by adding more experiments, in particular including measurements of two-phase flow properties, determining relative permeability, capillary pressure, wettability, and electrical properties. Due to the time-consuming and costly character of SCAL ...
Also, TEM-function can be used for averaging relative permeability curves (for each fluid phase separately, i.e., water, oil, gas, CO 2). [1]
Oil prices could soar more than 60% by early next year if conflict in the Middle East continues to escalate, according to Citi. The bank said oil prices could go as high as $120 per barrel in the ...

In 2016, largely in response to dramatically falling oil prices due to U.S. shale oil output, OPEC signed an agreement with 10 other oil-producing countries to create OPEC+. Josh Boak contributed ...
Correlating relative permeability. The simulation model computes the saturation change of three phases (oil, water and gas) and the pressure of each phase in each cell at each time step. As a result of declining pressure as in a reservoir depletion study, gas will be liberated from the oil.
