The company said a 750-HP rig is re-entering the well to try to seal the flow

A larger rig will spud by the end of July a relief well some 500 metres from Banjar Panji-1 and 350 metres from the "broach" where the mud is flowing from.

However, it may take up to two months from now to identify and cement the source of the mud, warned the company.
