Central Petroleum Limited (ASX:CTP) (“Central” or the “Company”) is pleased to advise that independent consultants RPS Energy Pty Ltd (“RPS”) concluded that the pressure transient data gathered during the production test of Surprise-1REH indicates that the well may access STOIIP (“Stock Tank Oil Initially In Place”) in the range of 0.5 to 2 million barrels in an area proximal to the well. No apparent boundaries were identified during the analysis of the pressure transient data. However, Central acknowledges that no further conclusions regarding the possible range of STOIIP volumes in the entire Surprise structure of c.8 km2 can be made until all available seismic, geological and geophysical data has been integrated and analysed.
RPS based their calculations on a 105m section of the horizontal well bore placed in the lower half of an 8m thick sandstone reservoir section with an average permeability of 50 milliDarcies and a vertical to horizontal permeability ratio of 10%.
