###A series of saturated and unsaturated triaxial tests were conducted on a sand-clay mixture. Results are shown in table below. Assume that the cohesion is zero and determine the internal friction angle , effective stress parameters at different values of suction and determine the air entry value
****Problem 4 A newly drilled well in a carbonate reservoir indicates a gross payzone thickness of 150 feet. The foot by foot porosity values vary all the way from .04 to 0.16. If we assume that porosity cut off is .07, 20% of porosity values are less than .07. The average porosity of values is 0.13. The average water saturation is 33%. The PVT analysis indicates API gravity of 35 with solution gas oil ratio of 800. Due to the highly heterogeneous nature of the reser- voir, the areal extent of the reservoir can be anywhere between 40 to 160 acres. Using Arps' and API methods, calculate the minimum and the
