Agadem Area Field Characteristics FIELD CHARACTERISTICS CNPC EXPLORATION WELL  Average discovery size is c.10mb, with no discoveries to date having been greater than 60mb  Typical discoveries in the primary Eocene play have an API of c31 degrees, a wax content of c.12 – 18%, a mid-20s pour point and a low sulphur content  Reservoirs are normally pressured and are thought to typically have porosity levels in the low- 20s percent, and permeability levels of c.250 milidarcies  Primary recovery factors of c.25% are typically assumed  Wells typically deliver oil production rates of between 1 – 3kbd, across up to 5 horizons on test CNPC CAMP SITE EXPLORATION DRILLING CHARACTERISTICS  Eocene well costs are c. US$4.25m per well (including completion)  Eocene wells average less than 25 days to TD  Exploration wells are vertical and are completed using industry standard methods TOPOGRAPHICAL LOCATION  The Agadem area is over 200km from the nearest major city and is in a largely population remote area  Located in a relatively benign desert environment 6 SOURCE: GOVERNMENT OF NIGER, SAVANNAH ESTIMATES
