Q2/ Discuss the following 1- The required properties of geological formation to determine its ability to form a good reservoir. 2- Using rotary drilling as an alternative to cable-tool drilling in the petroleum industry. 3- The cause of preferring the top drive system over the rotary table and kelly system. 4- How mud logging can determine the lithology of the drilled formation.
Styles Editin A production casing was planned to run in the production hole of a well with casing shoe at 15,000 ft. When casing was run empty to the mid depth, collapse safety factor was calculated to be 1.9. When the casing was at the bottom and full of a certain mud, safety factor of the collapse was calculated to be 2.75. If the mud weight of the fluid in the annulus was 14.0 ppg, determine the casing collapse rating and mud weight of the fluid inside the casing.

c) Indicate the two boreholes (between BH1 and BH5) where a Standard Penetration Test (SPT) needs to be carried out. What type and nature of samples can be obtained from this test?
The measured value of total number of blows (N) in a bore hole is found to be 20. The depth of the bore hole was 15 m. The water table was located 1.5 m below ground level. The soil is fine silty sand whose unit weight above and below the water table is 16 kN/m³ and 21 kN/m³ respectively. The corrected N value (in integer) would be
