Question 4.11 Consider the radial flow problem shown in top view (right), where the shaded area represents a damaged zone due to the drilling operations. Assume there are three horizontal layers of equal heights (thickness), and the permeability of the undamaged formation is 45 mD in layer 1, 25 mD in layer 2, and 30 mD in layer 3. Further assume that the radius of damage is 2.2 ft and the permeability of the damaged zone is 1.5 mD is 0.6 ft, and the radius of the reservoir is 450 ft. all the three layers. The radius of the wellbore a) What is the average permeability in each horizontal layer? b) What is the average permeability of the three layers?

Soil borings for the subsurface investigation of a site indicate a deep deposit of sandy soils. At one boring location, the blow count logged for the standard penetration test, N60, while sampling at a depth of 25 feet was 22 blows/ft. The sand has a unit weight of 115 pcf. Using criteria that relate SPT results and the soil angle of internal friction, estimate the value of f for the sand at the sample depth.
