ADST taken over the interval 1,715 – 1,736 mKB in the Milligans Formation recovered a quantity of gascut,salty water.REMARKS:The gas bearing sandstones encountered in the Milligans Formation in Bonaparte-2 were retested afterthe well reached total depth. A maximum stabilised flow rate of 32,500 m 3 /day was attained. Bonaparte-2 was plugged and abandoned as the gas discovery was thought to be uneconomic.STRATIGRAPHY (Bonaparte-2) :AGE UNIT FORMATION TOP(mKB)WEABER Point Springs Sandstone 5.2CARBONIFEROUS GROUP Tanmurra Formation 185.3Milligans Formation 480.7DEVONIAN COCKATOO GP Bonaparte Formation 2034.5
