From the well spud RNS below :

............The well is located just north of the Sea Lion 14/10-2 discovery well and 13 metres updip at top reservoir level. The well is designed to appraise the Sea Lion main fan reservoir and investigate hydrocarbon column and reservoir distribution. The location is 77 metres updip at top reservoir level from the recently drilled 14/10-4 appraisal well.
It is clear that they are drilling to test the Main Fan only. The last well found the Oil Water Contact and therefore defines they lowest level and now they are in the process of proving whether the upper levels also contain oil. When they have a bottom and top defined and both in contact they can call oil distribution across a very large area.
At this location the planned actions do not include Sea Lion Lower as it clearly states Sea Lion Main fan and at the updip top location.
From the RPS update on Sea Lion :

It is clear the average depth of the Sea Lion Main fan is expected to work out at 34.5 meters with thickening at down dip locations but potentially much thinner area's as well - hence an average of 34.5.
So this well is updip and therefore a figure in the 25 meter to 35 meter range should be hoped for, slightly below average expectation given this is updip and top of the reservoir, and not downdip where the much thicker net pay is expected to be.
I would be happy with 30 meters of net pay as a good result, anything more than 30 meters is very good.
As has been said we are not testing Sea Lion lower at this location and so net pay is purely about Main fan only, not a combination of Main and Lower as per the 14-10/2 well.
25 meters to 30 meters is ok.
30 meters to 35 meters is good given its updip and top location.
35 meters to 40 meters would be very good.
Above 40 meters and its an excellent result from this location for the main fan.
