Good morning Dan,
Well we only have limited information to work on. So we don't know if they took open hole samples before casing, we also don't know if they did sidewall coring before casing and testing. So is it possible that they have hit a water filled compartment in the deeper part of the well, perhaps. Water zones in a well, once identified, can be isolated and plugged. So yes what folks are describing does happen, we currently don't know how much of the 80m has been perforated to date. Wells are tested from the bottom up as its fairly straight forward to isolate and plug off lower sections while continuing to test upper sections. Clearly TO-14 is unfinished business otherwise they would have just plugged it now rather than return there after TO-13. Nitrogen is used in clean up operations, so it will be interesting to see what further updates come from both wells. The fact that Sonangol want to return to TO-14 after TO-13 is certainly positive.
The company does remain optimistic and positive given recent statements
15th April
"our ongoing optimism regarding the reactivation of the historic Tobias field in Angola."
28th March
"we remain positive, knowing we have encountered oil in the well and don't yet know its ultimate commercial prospectivity."
Its still a case of wait and see, we still don't know why Petrofina only produced from the top 8 metres of TO-4. There will be lots more news to come and hopefully we won't have to wait as long to get the flow test results from TO-13.
Regards,
Ed.
