Chinguetti Flow Rates, page-6

Ultimately, I expect ther the flow rate during the production test will be constrained by the testing equipment on the rig and the amount of oil that could be safely fed through the burners.

30,000 bpd may be achievable during actual production, but this is unlikely during production testing. Of course, they may have a very high rate for a short period of time - just to excite the market.
