Abstract


Attention towards exploration and development of fractured basement reservoirs has been on the rise as it holds great potential as a promising unconventional play. Conventional petrophysical assessing methods are often unfit for basement reservoirs because of the intricate nature of basement which leads to uncertainty in formation evaluation. In such reservoirs, mainly secondary porosity system exists (fractures/faults) which are dominantly due to tectonic activity and scaling from macro to micro levels, being the most significant and often the only component contributing to the production.
