A dynamic systems analysis was made of the problem of the ''rocket-type'' launching of a well-casing, tubing string from a well at a hole depth of 3300 feet. The objective of this analysis was to assess whether the observed ''rocket-type'' launching of the tubing string could have been caused by nozzle-breakthrough or tubing failure at the SRC No. 1 in Eddy County, New Mexico. The analysis considers tubing weight, fluid buoyancy, external fluid drag and fluid thrust forces on the tubing string. The tubing string and the fluid columns in the moving string and the annular region external to the tubing string are considered as a coupled dynamic system. Several situations of interest are considered relevant to the dynamic behavior of and hence implied failure mode for the tubing string. Summary plots show typical dynamic behavior as a function of internal shut-in pressure and tubing nozzle diameter.
