gas in nullara, page-21

PC43, here's a technical question: given that the Nullara seems to be too porous/permeable to drill deeper (mud losses could lead to loss of well control, and they don't want to lose the opportunity to test what they have got) how can they ever get to the bottom of the Nullara to see what else might be there, or size of gas/fluid column? They don't intend to do that with this well. Could it be done some other way, eg, another well with lots of LCM?
