103-ft aggregate perforated zone within the Upper Portland sandstone interval at a depth of approximately 615 metres below ground level, flowed via rod pumping as follows,
Oil 37o API, Flow rates 168 bopd, Oil 100%, Water 0%, Duration of flow test 9 hours.

The shallower Upper Kimmeridge limestone and Portland sandstone zones at approximately 840 and 615 metres below ground level,
Oil 40o API, Flow rates 465 bopd, Oil 100%, Water 0%, Duration of flow test 9.5 hours on 28/64" choke.

80-foot zone within the Lower Kimmeridge limestone interval at a depth of approximately 900 metres below ground level
1st test on Lower Kimmeridge: Oil 40o API, Flow rates 700 bopd, Oil 50%, Water 50%, duration of flow test, not disclosed but on 1" choke.
2nd test on Lower Kimmeridge: Oil 40o API, Flow rates 463 bopd, Oil 99%, Water 1%, duration of flow test 7.3 hours on 1/2" choke. Moving to a 28/64" or 20/64" choke should stop water form the Lower K.

So water contact is in the basement Lower Kimmeridge, reducing the choke size will stop the venturi effect water carry to the surface.
Not commenting on the reduction in bopd from the Lower K.
