Central Petroleum Limited, an operator of the Southern Georgina joint venture, has announced that it is continuing coring at Gaudi-1 well, having reached a depth of 2,157 metres in the Lower Arthur Creek Formation. There have been 8 cores taken to date representing over 10 percent of the total expected to be taken for Gaudi-1.
Central Petroleum Limited is an ASX listed junior exploration and production company operating the largest holding of prospective onshore acreage in Australia totalling over 270,000 km2, c.70 million acres, mainly in the Northern Territory with smaller holdings in Western Australia, South Australia and Queensland.
In May 2013, Central Petroleum completed the farm-out transaction with French energy company Total in respect of the three Queensland permits for the exploration of approx. 6 million acres in the Southern Georgina Basin.
Gaudi-1 is the second well in a program of unconventional gas exploration wells operated by Central (via subsidiary Merlin Energy in partnership with Total) and is being drilled using Enerdrill Rig 2. The primary objective is the Lower Arthur Creek Formation, which will be fully cored and sampled for gas desorption and reservoir properties, in addition to an extensive logging program to evaluate the hydrocarbon resource potential.
With the Southern Georgina Joint Venture evaluating the unconventional shale gas potential of the Arthur Creek formation, coring is a precursor to the design of production wells. So far there have been 8 cores taken to date representing over 10 percent of the total expected to be taken for Gaudi-1.
The objective of the Gaudi-1 well is to place into sealed canisters cores of the shale or siltstone with the gas still embedded for desorption analysis (ie the rate at which gas will be released from the host rock) giving the gas content. The fact that the cores are desorbing (releasing) gas is a positive early sign. Results of the desorption analysis will be released as soon as they are known.
