The 1.3 billion is the entire South Lochichar basin including multiple prospects and dozens of wells not just Ngamia. Ngamia alone is not even close to that. Also the 45 million Ngamia estimate is risked P50. The 66 million from Tarach is unrisked. If we use a 20% COS Tarach would be 13.2 million if we compare on an equal basis.
So no I am not calling Africa Oil a liar. What I am saying is a lot of people have no understanding of the numbers and as a result are making completely invalid comparisons.
