e Snoek and with Liza deep previously likely moves recoverable resource closer to the upper end of this range 2bn boe before Liza #4 and Pacuma, providing line of sight for at least a 4 FPSO development starting in 2019. e After Liza 4, the Stena Carron drillship will move back to Payara to drill an appraisal well which will also test a deeper prospect ‘Pacuma tail’. Where pre- drill prospect size is scaled at about 1bn boe. The next prospect (Turbot) will then be spud south east of Payara. Note is that if Payara 2 is successful, this would likely add another ‘boat’ with capacity of 150,000 boepd. The graphics below characterize Hess view of Payara and Snoek. We assume the 1bn boe Pacuma prospect is the light green area below Payara.

However at this early stage we assume no value for Payara in our assessed value of Hess’ not least as any attempt at precision is obviously premature. But with discussions with management suggesting scenarios through appraisal where Payara is a lookalike to Liza, we believe a ‘plus three year’ development scheme is a reasonable basis to frame option value in a success case. Under our $70 Brent base case, the theoretical NPV would be around $10/sh. This is on top of the approximate $12-14/ share value we estimate is reasonable for Hess from the existing Liza d
