UMBRA an Afren Poster hinted 5-6 Billion Bbls in BL 1
so the entire zone could be what 15-30 Billion ??

original estimates below

In 1999, Geco-Prakla (now WesternGeco) shot a 2D seismic survey of approximately 5,900km covering the major part of the JDZ and EEZ.

Interpretation carried out by WesternGeco has enabled the identification of 56 prospective structures within Blocks 1 to 9 in the JDZ, of which 17 were defined as prospects and 39 as leads.

WesternGeco used reservoir parameters similar to those known from nearby fields in Nigeria and Equatorial Guinea. Combined recoverable reserves potential of the 17 prospects was estimated by WesternGeco to be 14.4 billion barrels of oil. [4.5 Billion in BL 1,2,4]

The scope of the WesternGeco report was to interpret and map seismic data, highlight prospectivity, and calculate volumetrics.
