Bridgedogg,
The comingled production figures, unexplained and scant as they are, represent the production from the fractured Kimmeridge, as should the KL3 and KL4 individual flow rates according to what has been stated - that the Kimmeridge produces from a single oil pool, due to the fracturing in both shale and micrites, from KL2 to 'at least the top of the KL4'.
Because of the scant data there is scope for speculation about the rates. What has been released for the comingled test is a real mixture of rates, half hour rates (and pboo, a maximum half hour rate is just that, every other half hour was less), and then an average over a week, then an hourly rate immediately following the dewaxing...…………. and in the 18 Feb RNS nothing about comingled flow rates except overall volumes which gave a total of about 4000 bbls produced from the Kimmeridge after the 16 January RNS.
But in general the longer Kimmeridge flow periods where average rates have been released seem to average between 300 and 350 bopd, having started at a higher rate following a shut in period, so presumably ending at a lower rate.
But there is no information on flow rates for the two longest periods of flowing the Kimmeridge except for the initial rate at the start of each extended period, the Xmas period initial rate 426 bopd (KL3) and then KL3 & KL4 prior to the changeover to Portland, initial rate at start of period 351bopd.
Whilst many will speculate over chokes and pump rates influencing the comparability of the rates the absence of flow rate information for the longer term tests to me is not entirely encouraging.
It will be interesting to see what rates are released during the Kimmeridge testing that appears to have just begun.
