Abstract : Computations based on the extreme values of compression and extension of the fishes' swim bladder in response to the explosion pressure field were used to estimate lethal ranges from wellhead severance explosions. The computations were done using an equivalent-weight bare charge in free water which was matched to measured data -- shockwave peak pressure, decay constant and impulse -- from a 1/2-scale wellhead-model explosion test. Results are x,y-contour plots of 10%, 50% and 90% kill probability for 1-oz, 1-lb and 30-lb swimbladder fish in water 200, 500 and 1000 feet deep.
