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%.

Sandstone is a sedimentary rock which is made up of sand grains which have been compressed to form a rock that has very weak bonds holding the grains together. The grains them â¦ selves can be igneous, sedimentary or metamorphic depending on which rock the grains were eroded from. 1 person found this useful.
