HC05 was drilled by the McDermott Rig 28 to a total depth of 900m and intersected a 3.5m seam at the interval between 800-803.5m that showed promising results from early onsite desorption results.
Sample cores from the corehole in PEL 267 are undergoing the full desorption process to determine the gas content, gas composition and gas saturation values.
This will allow the company to ascertain the coal seam methane production potential of the seams.
HC05 has since been plugged and abandoned after the logging of geophysical data for lithology identification and subsequent coal seam reservoir characterisation, and the rig is mobilising to the HC06 site in PEL 4.
Sydney Gas is drilling 10 coreholes in PEL 4 and PEL 267 as the initial phase of its exploration program to prove up potential 2P (proven and possible) reserves in the Hunter region.
It is also planning to carry out an extended corehole program in both permits to prove up additional 2P reserves.
Meanwhile, the company said it had processed 93km of 2D seismic data in the Hunter region covering Merriwa, Howes Valley, Broke, Bulga and Jerrys Plains.
The data is being interpreted and calibrated with the corehole data to map the sub-surface geological structures and define the lateral continuity of the targeted seams in the Hunter region.
