Good presentation Mustapha. I think in your example we have a water-wet system/reservoir since the oil & water relative permeability curve intercept at Sw more than 0.5. My question please. If your special core analysis (SCAL) report only has the endpoint values without Corey exponents for oil and water (Nw & No are not given). how do you generate your relative permeability table. (what is the specific empirical formular is used to estimate REL perm values) Thank you
good afternoon, in the case you are giving an example of : you have a water-wet rock and not a mixed-wet rock. Because the wettability can be defined on the basis of : at what water saturation do your plots of oil and water relative permeability cross. If your oil/water relative permeabilities plots cross at a water saturation Sw less then 0.5 then it is an oil-wet rock. If your oil/water relative permeabilities plots cross at a water saturation Sw greater then 0.5 then it is a water-wet rock. In your case : the oil/water relative permeabilities plots cross at a water saturation around Sw= 0.65-0.66 which means that it is a water-wet rock.
Thanks for sharing
