Here is the first comprehensive map of Chad oil blocks that I have seen (all credit goes to kingpindg for finding this):



As kingpindg noted, there are three areas labeled Chari Block I, II, & III (could these be blocks 1, 2, & 3?). It would seem that one of the areas in the southern part of the country would be the one leased to ERHC (probably the one next to BDS-2008), based on this description:

"In the last quarter of 2004, Energem signed up to explore a large tranche of acreage that was relinquished by ExxonMobil in land-locked Chad. The Chari-Ouest concession area lies in the centre of the Doba Basin adjacent to the US oil giant's production complex, which includes access to an export pipeline to the coast. firstAfrica has an option to acquire the Chad project from Energem." - (source link)

The Doba Basin is in the southern part of the country, as well as the Chari River:



But the main import of the block map is that ERHC has apparently landed some pretty huge acreage (again!). - Longtimer
