oil begins to flow from surprise, page-9

Its an extended production test, I wouldn't expect any information for a few weeks from commencement. Depending on the testing strategy it may be a multi-rate flow test in which they flow the well at pre determined rates for several days/weeks. I'd imagine they would start off at relatively low rates - nothing that would excite or be meaningful to the market.
Trucking rates in WA are about $6 per Bbl from Dongara area to Kwinana refinery (450Km). Not sure where the oil from EPT is going - possibly Whyalla to the Santos facility. In which case trucking costs could be well over $20/bbl.
