Estimation of new relative permeability curves due to compaction case study at bachaquero field – Venezuela

Abstract

This paper is written to analyse the variation of water production due to compaction in a field in Venezuela. The producing water, after being analysed, was suspected not from aquifer. So where does the water come from? The results shows that pore structures of reservoir changed, and producing water is due to volume changes of immobile water and mobile water as the result of compaction. It means that relative permeability curves have changed when rock deforms.
