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.
