Question

State the position of maximum and minimum circumferential and radial stress in a solid rotating disc

Answer 1

Answer:

The difference in wellbore pressure and pore pressure causes radial stress, which acts along the wellbore's radius. Fluid pressure acting equally in both directions causes both wellbore and pore pressure. As a result, under radial stress, the pressure differential acts perpendicular to the wellbore wall and along the radius of the wellbore.

Explanation:

1. The amplitude and orientation of in situ stress, pore pressure, and wellbore inclination and direction all influence axial stress.
2. Mud weight has no direct effect on axial stress.
3. A vertical well with equal horizontal stress has the same axial and vertical stresses.
4. The resolution of the overburden and horizontal stresses in a deviated well called axial stress.
