Determination of source and breakthrough mechanism of water production in Thang Long field fractured basement reservoir by Stiff diagram method
Abstract
During the production phase, produced water has been constantly analysed to monitor well performance and water encroachment so as to come up with a mitigation plan to optimise production and diagnose scale deposit and erosion. In this paper, the Stiff diagram is employed to evaluate the water source by plotting chemical indicators and determine the water-out mechanism in the production wells of Thang Long field by a hypothesis developed by K.S.Chan. Those methods have the advantages of being simple, handy and cost-effective which allow the operators to easily monitor production, determine the water breakthrough mechanism and optimise well production performance in the long run.
