PGE 362 Extra Credit Solution Please turn in the last day of class. Please estimate the theoretical flow rate from the BP Deep Water Horizon blow out. Assumptions: The reservoir is a high quality under saturated oil with the following properties. 0 3 m 200' 500 md 1.3 bbl/STB =0.7 cp 40 lb /ft 7500 psi BHT=260 deg F 5,280' 0.36' 0 o o e e w h k B p r r s μ ρ = = = = = = = = The marine riser has snapped off at the top of the subsea blow out preventors. The well is flowing between the 9 5/8” intermediate casing and the 7” production casing and is not restricted at the blow out preventors. The flow system to the sea floor is described as follows. Intermediate casing: 9 5/8" OD (8.7" ID) Production casing: 7" OD Well Depth = 18,000' Sea Depth = 5,000' Sea Water Pressure Gradient = 0.44 psi/ft Ocean Floor Temperature = 75 deg F
