Sydney - Tuesday - November 30: (RWE Australian Business News) -
Karoon Gas Australia Ltd reports the Megascolides–1 well (in Narracan
Trough, western Gippsland Basin, Victoria) had reached a depth of 1110m
in an 8 1/2-inch hole.
The well penetrated the top of the main coal interval at 710m
RT, close to prediction.
At 1005m within the CBM target interval, continuous coring
commenced in interbedded tight sandstones shales and coals to a depth of
1110m RT.
Coals to more than 1m thick were cored and are currently
undergoing analysis.
A 1m coal core is being analysed through gas desorption testing.
Karoon says early qualitative results show gas is present on the
coal and gas desorbsion is occurring.
This is supported by mud logging data showing methane, ethane,
propane, butane and pentane through the cored section with high peaks
associated with the coals.
Preliminary seismic/drilling results calibration shows a good
relationship between the presence of the thicker coals and seismic
amplitudes.
"When all the well data is collected and analysed there will be
a sound basis for more quantitatively identifying CBM 'sweet spots' on
the seismic.
"The analysis so far indicates that the optional Invermay-1
drill location has better seismic indications for coal at shallower
depths," Karoon says.
