Successful Saturation Monitoring in a Shaly Sandstone Reservoir - A Case Study from Partitioned Neutral Zone between Kuwait and Saudi Arabia

Optimizing production from existing boreholes requires the detection and evaluation of bypassed hydrocarbon and the ability<br>to track fluid movement in the reservoir. Logging through casing is an important acquisition technique for this application.<br>There are a number of measurements which provide reservoir saturation monitoring through casing, however each technology<br>has limitations. The factors limiting the application of different measurement types relate to formation properties, completion<br>type and production characteristics of the well. The selection of the most suitable technology requires consideration of the<br>effect of the completion, well dynamics and formation characteristics on different measurements in addition to an<br>understanding of the measurement physics.
