king, that is one of the questions I asked on today's chat but they didn't get to it:
"CPC's OPIC recently made a notable discovery in "Bloc Chari Ouest III" with its Benoy-1 well. Is this the same block that ERHC gained an interest in (a relinquished portion)?"
So there is still some mystery about exactly where ERHC's leasehold is. However, in today's PSC-signing news release, they did say, "Two of the Blocks, BDS 2008 and Chari-Ouest Block 3, lie next to the Doba Basin oilfield."
The "Chari Ouest Block III" leased by OPIC fits this description, as shown below:
So my thinking is the same as yours, that ERHC acquired a portion of OPIC's block due to relinquishment. - LT
