E. Conclusions of the static model review

Although some precious insights could have been gained if the static model Petrel project was made available for the review, the detailed report made by Sonangol nevertheless indicates that:

• The water saturation modelling methodology is not adequate. One could use a saturation height function (J-function, Thomeer) even though the Free Water
Level (FWL) is unknown. COS-1 water gradient can be used to intersect the oil gradient from the Espadarte wells and provide a base case. The low case would be the Oil Down To (ODT) observed on ESP-1 and a high case the Water Up To (WUT) on COS-1.
• The permeability model cannot be QCed in the absence of the source data used.
