The 13.375 lower section was pressure tested to 904 psi @ 80@ of the casing collapse pressure. The 8.625 was tested to 2,744 psi @ 80% of the casing collapse pressure due to the casing being set in slips and not the mandrel well head. The 5.5 casing well head was tested to full working pressure at 10,000 psi. Initially on 01/17/2016 the well was found to have a annular volume pressure of 2,250 psi between the 5.5 annular and 9.625 internal casing areas.
