oa Through-casing Reservoir Monitoring: Method of Water Investigation in Very Low Water-Cut Wells in Southern Iraq

Water production in early field life poses a challenge to field development. This paper describes a study from a giant oil field in southern Iraq where evidence of minor amount of water production was seen in a few wells by monitoring the salt content of the produced well fluids.

With multiple producing layers in the wells, an investigation for the water source then became necessary in order to plan remediation and change future development plans. Limitations on the produced-water capacity in the field required immediate investigation of the source of water.

This paper describes how careful data acquisition delineated the water producing layers in the reservoir.
