Assignment $4$: Drilling

Task $1$: Fill the given table with the actual dimensions of the casings and the bits used in the typical Chissonga development well, shown in the figure below. Use the provided casing tables to read the required information.

Figure $1$: Typical Chissonga Development Well Casing Deepwater Angola.$($Maersk Oil$)$

NOTE: "Minimum internal yield pressure" means the minimum internal pressure at which permanent casing deformation could take place assuming no external pressure.

Task $2$: Using the diameters of the casing and bit along with the vertical distances of the cemented sections $($see figure $1)$ after each casing. Calculate the volume of cement needed per casing. Assume that the height of the section inside every casing is $3$ ft $.$ Remember that the section inside the casing do not appear in the figure because they are destroyed when the following bit comes to initially the new hole.
