RE: low volumes11 Apr 2018 17:24
From what i see we only have figures for the Upper Sokor and the Sokor Alternances. We may/may not be in the window for the Madama and Yogou targets and definitely not the Donga (see previous post) as we drill to just over 2100m. The potential could be more but for now dealing with the two targets indicated where figures were provided.
From CCG in the relist document Dec 2017 -
1. Upper Sokor Formation (secondary target at circa 1200m)
This represents a potentially important new play in the basin, and so has warranted particular scrutiny. This new play is supported by seismic, hydrocarbon shows and well testing.
Consequently, the Upper Sokor is underrepresented in the existing well data sets, so estimation of resource potential at this level cannot be determined directly from the existing exploration statistics.
2. Sokor Alternances Formation (primary target at circa 1600m)
This play has been extensively drilled within the retained acreage of the Agadem Rift Basin, and the discovery data mostly reflect the success of this play.
3. Madama Formation
The Madama Formation is present in all wells drilled to that depth across the basin.
In many fault blocks, the Madama Formation may carry attic oil trapped against shales in the Lower Sokor Alternances. CGG thus views the Madama Formation as a potential subject of prospective resource volume upside.
4. Yogou Formation (mainly fault seal trap risk)
Review of the available log profiles suggests that multiple reservoir-seal couplets are present in the Yogou, and as long as there are on average four or more of these, then the numbers of separate accumulations at Yogou and Eocene Sokor Alternances levels can be expected to be similar.
The reduction in numbers of faults with depth suggests that the size of individual fault block traps will be greater at Yogou than at Eocene levels. Recently, testing of the Upper Cretaceous Yogou reservoirs has proven productive, giving similar, or better, flow rates than in the Eocene section.
5. Lower Yogou and Donga Formation
In some parts of Savannah�s acreage these intervals are found at depths that are relatively easily drillable. Savannah has only recently evaluated the play potential in this stratigraphic interval, following on from its detailed investigations of the Upper Yogou prospectivity. For this reason, Savannah has not yet interpreted the interval to the level where prospects and leads can be added to its proprietary exploration portfolio.
