Nige,
Those comments made by CRCL were in relation to horizontal wells. This first well is to confirm their interpretation of the oil in place and the 60 odd mmbbls of contingent. So the well is an infill well into the large field, the field covers 3400 acres so its quite big. Tobias-13 is a vertical well, like a proof of concept, given the current oil price and the volume of contingent they'll not need to hit much to get a commercial onshore well. Sonangol will have picked what they believe will be their best spot to achieve that in this previously producing field, so bells and whistles came out with the minerals/oil and gas minister. So imo a high probability of success for the infill location.
If successful and they get similar to the 100m oil column they'll then select one or more locations and that may include horizontal development wells. Its those horizontal wells that may increase the oil in place as mentioned by the company. Certainly not essential though, 60mmbbls odd gross onshore at the current oil price is more than enough. Horizontal wells as you know could do several times the amount of production that a vertical well can do, also suitable for carbonate/limestone as they can hit more natural fractures etc. Its possible that with modern horizontal wells and modern logging they may interpret the pay better than then 90's. An increase in oil in place in combination with modern logging and completion may increase the contingent resource recoverable, in theory certainly. There's been a lot of developments in tech since the 1990s, like directional drilling, logging while drilling, a lot of it is now done digitally.
So I'm not counting my chickens until I see the TD RNS but I'm certainly hopeful that this infill well will be positive. Angola are looking to revive their onshore Kwanza production this is the well they've chosen to do that and we've 18% of it. Lets be avin it.
