CONCLUSIONS
• A holistic approach to the determination of aquifer porosity was introduced utilizing the newly developed lithology
measurement technique (ECS*).
• Multi depth of investigation resistivity measuring tool (AIT*) was used to predict, in real time, which layers of
the aquifer are permeable, as well as estimating an accurate aquifer resistivity.
• The Nuclear Magnetic Resonance (CMR*) was introduced to differentiate between free water,capillary bound
water, and clay bound water. A calibration coefficient from measured permeability to aquifer conductivity was
also derived.
• The Formation Micro Imager (FMI*) was used to qualitatively identify which layers in the aquifer are vertically
homogenous, as well as detecting fractured layers.
• Modern state-of-the-art logging tools allow measuring the physical properties that control the behaviour and per
formance of an aquifer. It allows to build a quantitative model of the aquifer that can be used in a predictive
manner to locate additional production wells or to monitor an ASR project.
