Why dont they deepen this in one go, now that they have got a suitable rig? Pulling the rig out, production testing, then having to re-drill seems be dragging out the process? How long more would it take to drill 300 metres?
"The BD-260 rig will complete the workover of Z-21 by pulling out the entire tubing string from the well, cleaning out the casing to the well's total depth, 3,982 metres, and subsequently performing a number of production tests. In the event that a satisfactory rate of production was not to be achieved from Z-21 following these operations, the Company would proceed with deepening well Z-21 beyond the Maykop formation into the Eocene and Upper Cretaceous formations by drilling an additional 300 metres, extending the well's total depth to approximately 4,270-4,300 metres.
