Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Question

If the total ocean bottom depth is 5500 ft and the first layer depth is 13000 ft and the
second layer depth is 15000 ft. The specific gravity of the rock in the first layer is 2.65
gm/cc while the second is 2.71 gm/c. Calculate the temperature, hydrostatic pressure,
lithostatic pressure, and the effective pressure. Assume the temperature gradient is
1.25 °F/100 ft. What is optimum drilling mud density (Ib/ft') used if an oil well to be
drilled to depth of 15000 ft in this formation?
