Still trying to find out what is meant by initial - the only other flow rate i could find that mentioned something close to stabilised was back in Aus 2007

"Production operations have now commenced at Clear Creek with
the Ridge Runner 11-17 well averaging sustainable gas
production at a rate of over 7 million cubic feet of gas per day(mmcf/day) over a seven day period"

the meaning of INITIAL really is the key, either way, nice to know that there is stable flow rates of some level, would expect to see a rise tomorrow
