Woolside signed the rig contract with Songa on 4Sep09. The drilling contract is for a 75days period(with possible extensions). Woolside started the drilling on 11Sep09, so possiblly, OEX's rig will be available to drill at the end of Novenber(around 24,25nov).
Now I have some solid reasons to hold my OEX for another 3 months.
Cheers.
