On a ‘risked’ basis, we believe this is a reasonable development scenario representative of any incremental discovery that resembles Liza recalling that the partners have identified over 20 additional drilling prospects. On the assumption of a ‘plus three year’ development scenario after Liza, the potential impact on incremental production and cash flow is significant for Hess while the cumulative impact also becomes significant for XOM. The charts below show our latest assessment of how a compound timeline for a Liza / Payara development could look, if Payara as a project does indeed prove to be a look alike to Liza.

This appears confirmed again by the latest ‘Snoek’ SUCCESS. XOM’s development plan calls for an FPSO (floating production and storage offloading vessel} with production capacity of about 150,000 boepd for every 450mm barrels of recoverable reserves, with plateau production extending up to 10 years. We suggest management’s commentary supports gross production capacity from current discovered resource of at least 600,000 boepd.
