Strategyone,
Sorry dude, but the NSAI were for each individual blocks, not drill sites.
"In 2009, the independent engineering firm, Netherland, Sewell & Associates, Inc. (NSAI) released a Resources Assessment for ERHC that examined unrisked and risked prospective resources for JDZ Blocks 2, 3 and 4. The NSAI report estimated ERHC's unrisked prospective resources in those JDZ Blocks totaled more than 336 million barrels of oil and 372 billion cubic feet of natural gas (P50). The NSAI report estimated ERHC risked prospective resources in JDZ Blocks 2, 3 and 4 totaled 135.5 million barrels of oil and 144 billion cubic feet of natural gas (P50)."
