Capillary curve
WebFeb 24, 2014 · Capillary pressure curves directly determine the irreducible water saturation, residual oil saturation, and rock wettability and can be used to determine water oil contact point and approximate oil recovery. Web6. What effect does structure have on the soil moisture characteristic curve? Distinguish between a curve for a structured and compacted soil. Structure may increase total pore space and does increase the amount of macro-porosity (fraction of pore space composed of large pores). Thus, a structured soil gives a moisture characteristic curve that has higher …
