Dumping syndrome, or ârapid gastric emptyingâ, is extremely common following bariatric surgery procedures that bypass the majority of your stomach. Believe it or not, for many weight loss surgery patients it is actually a good thing despite its unpleasant symptomsâ¦.
Estimate the total reservoir compressibility for a sandstone formation that is characterized by a porosity of 25%. The reservoir is undersaturated (i.e., no initial gas cap is present) and the oil and water saturations are 70 and 30%, respectively.stimate the total reservoir compressibility for a sandstone formation that is characterized by a porosity of 25%.

(2.23) reduces to; epdPdVbbV1cmï³ï½ (2.24) which is defined as the grain or matrix compressibility, c m, the change in volume of individual rock grains, with respect to a change in pressure at constant temperature. Typically matrix compressibility is small and frequently ignored.n liquid-saturated compressible rocks, B = 1.0; when the porous space is partially saturated, be estimated from, )fl/ cm(1 c1Bï« ï¦ï½ (2.21) where c m and c fl are the compressibilities of the rock and fluids(water) in the void space, respectively.
