Extended Well Test ("EWT") Overview
The 2016 short flow test campaign established commercially viable initial flow rates for each of the Portland, KL4 and KL3 zones, the 2018 EWT's prime goal is to confirm that the wellbore is connected to a commercially viable oil volume within one or more of the three zones.
The long-term reservoir performance data is also expected to provide the necessary data to enable, for the first time, Petroleum Resources Management System compliant Kimmeridge and Portland reserve figures to be estimated at Horse Hill
Each test sequence will include a short, optimised rate test, together with a sequence of "choked back" (i.e. reduced) steady-state flow periods necessary to obtain the data required to determine the connected oil volume within each zone. A series of associated long pressure build up tests are also planned. Oil produced from the EWT will be sold on the "spot" oil market and any revenues will be utilised to offset overall testing costs.
In light of the fact that not many road tankers are being seen, we can assume that no oil is being produced and so we must be in the period of "associated long pressure build up testing" as mentioned above?
