Question: Because problem data needs to be consistent, these problems must be solved continuously. Calculate the buoyancy factor if the wellbore is full of a drilling

Because problem data needs to be consistent, these problems must be solved continuously.

Calculate the buoyancy factor if the wellbore is full of a drilling fluid with a density of 1100 kg/m and the drill string steel specific gravity is assumed to be 7.75. (1) Calculate the buoyed force exerted by a single joint of the following string components assuming the bit is off bottom and the well is full of 1100 kg/ mmud. Show one example of your calculations required to fill out this table in the space provided below the table. (6) Component Average Length, m Dry Weight, kg/m Buoyed Force, daNjt 8 DC 9.6 6-1/2" DC 9.45 HWDP 9.3 DP - premium "Premium DP has a minimum of 80% of its original wall thickness 9.5 If the maximum weight on bit required for this portion of the hole is 15 kdaN, how many additional HWDP would be required? Assume that no more than two 84 and eight 6" collars can be used, and that a design factor of 1.2 applies to only the top component in the BHA (5) Calculate the buoyancy factor if the wellbore is full of a drilling fluid with a density of 1100 kg/m and the drill string steel specific gravity is assumed to be 7.75.
