Unconventional Hydrocarbons

Modelling of unconventional hydrocarbon reservoirs requires a unique approach to the application of conventional volumetric and dynamic workflows. As the name suggests, the methods are unconventional, and the ability to identify the key issues and determine a suitable techniques and proxies is essential.

In the example of fractured basement, the notion of net-rock and porosity can quite easily and quickly become meaningless if the data shows fluid filled voids and caves. Fracture density and orientation are also important to both in-place volumetrics and recoverable reserves, the need to have a flexible and adjustable model to capture the uncertainties of this is key.
