Figure 3-43, Layer Properties with Reduced Permeability Values
Simulating complex fractures with fissure openings provide an 11% increase in production from the base
case, while a complex fracture network similar to that of the Barnett provides a 45% increase in
production from the base case.
The petrophysical evaluation describes the Posidonia to be a ductile formation indicating that the most
probable fracture geometry that is created would be planar. However, it is interesting to note that even
in a complex fracture network scenario of the base case, the production forecast at the end of 15 years
is closely equivalent to that of an extended lateral scenario of the base case, although initial cumulative
production is lower.
It is the recommendation of this report that accurate permeability measurements of the Posidonia
formation are obtained to achieve a more likely production forecast. Once the first well is drilled and
produced, permeability along with other reservoir properties can be better understood. Operationally,
it is recommended that lateral length be extended as long as feasible taking into consideration
environmental and mechanical constraints.
