RE: Drill Penetration Rates. Your initial post suggested that based on the Heritage well, lfd would have no problem drilling a well in the time remaining before the psc deadline in June. Based on geology and pressure regimes, this comparison is completely irrelevant.
You continue to predict that lfd will not have to deal with high pressures at Chia, when historical data from the old wells and recent examples from WZG, which drilled identical formations, clearly indicate otherwise.
The shallow oil zones in first wells at Chia suggest that oil has leaked from the underlying primary zone, which is also what happened at Sarqala. This means that high pressures may be encountered unexpectedly at any depth and are essentially unpredictable. Prudent practise means cautious drilling, more casing strings and heavier drilling mud which will result in slower and more expensive drilling.
On top of everything else, shareholders do not want lfd to rush into drilling without proper techniques and blunder into some catastrophic drilling incident. Very definitely high pressures will be a challenge, which proper dd will quickly confirm.
