Exploration Petrophysics for Intra-Salt Carbonate in Ultra Saline Environment

Intra-salt carbonate stringers are the Early Cambrian source rocks and reservoir in the South Oman salt basin. Reservoirs are<br>over-pressured and drilled with salt-saturated heavy barite mud. Formation water is ultra-saline (>300kppm), general<br>porosities are low (< 7%) and salt is often found filling part of the pore space. Each reservoir character creates a contrasting<br>scenario for resistivity evaluation.
