IDT-9 ST2 is being drilled by Parker Rig 226 which is re-entering and sidetracking from an existing shut-in well, IDT-9 ST1.
This well produced oil for a number of years from a separate fault block before watering out in 2001, when the well was shut-in.
The extension has the potential of delineating up to 60 million barrels of oil-in-place in the Toro and Iagifu sandstones, with approximately 6 million barrels recoverable from this well.
The company said should hydrocarbons be intersected by IDT-9 ST2, the well could be immediately tied into the central processing facility for production testing using the existing flowline.
