the reason why dharoor seismic finished early

It is all there in the AOI September quarterly.

'AOI have fulfilled spending it's sole funding commitment associated with the Joint Venture Agreement in the Dharoor block and thus has earned it's 80% working interest.'

AOI have spent the $22,500,000 required and for that amount only 782 kms of 2D vibroseis data was able to be completed. AOI and RRS currently do not have the funds to complete the stated 2600 kms of seismic. There is no other reason.
