The 2600m well is drilled to a reservoir. The SG till depth 1000 meter is 0.43 and from 1000 to 2600 m is 0.7 psi/ft. The drilling at reservoir is done using 12ppg mud. It is planned to inject acid with 5800psi after the completion. Design the casing for hole economically (casing will be 9 5/8 inch OD for this case). The table for casing strengths is given. DF for tension, collapse and burst are 1.8, 1.125 and 1.1 respectively. Design for worst possible cases. Sketch the casing structure for 9 5/8 inch and draw the graph for burst collapse and tension. grade k55 k55 k55 k55 n80 n80 n80 n80 #/ft 37 40 43.5 47 40 43.5 47 53 ID 8.83 8.75 8.68 8.53 8.83 8.75 8.68 8.53 Burst 5200 5500 6400 7200 5700 6400 6900 7900 Collapse 3000 3500 4000 4700 3000 4000 5000 6500 The 2600m well is drilled to a reservoir.
