Balcombe Field Discovery - post test analysis of 7-day well test suggests high probability continuous oil with a low watercut can be produced
The Balcombe Field Discovery is considered to be in the ‘sweet spot’ of England’s Weald Basin given the 568 metre thickness and highest maturity of the Kimmeridge Layers.
On 2 October 2018 the Company announced the results of the completed horizontal well test of the Balcombe-2Z’s Kimmeridge Layer as having naturally flowed at 853 bopd equivalent, not including 22.5% water. A second flow period was undertaken with the well flowing naturally at 1,587 bopd
equivalent, not including 6.6% water.
Post-test analysis of the recovered water demonstrated levels of salinity significantly higher than any regional trend, indicating a strong probability that injected brine rather than formation water was being produced from the site’s Micrite Layers. Given the mandated length of the short testing sequence, the
Company was not able to remove what it now believes is a limited amount of unrecovered brine from previous activities at the site.
