摘　　要：When producing from conventional fields,the well rates are primarily constrained by the production-system in the early years of the field-life,while later in the field-life the production rates are primar-ily constrained by the reservoir deliverability.For the post-plateau production period,the reservoir deliverability will no longer potentially exceed the production-system well-rate constraints.Tradition-ally,analytical equations are used in a nodal analysis method that balances the pressure at the well inflow point from the reservoir(inflow performance relationship;IPR)with the pressure required for the vertical lift performance(VLP;or vertical flow performance;VFP)from the same point upward.A faster and simpler approach is proposed in the present study.Whereas,the classical IPR solutions are based on a constant well-rate solution of the diffusivity equation,use of a constant bottomhole pressure assumption can bypass the need for nodal analysis type pressure matching solutions to obtain the well rate.Instead,the well rate can be directly computed from the pressure decline in the reservoir and any production system capacity constraint can be imposed on the theoretical well rate due to the reservoir quality.The merits of the new approach are explained and illustrated by way of a detailed production analysis case study using open-access data from the Volve Field(Norwegian Continental Shelf).In addition,the case study of the Volve Field wells demonstrates a new water-breakthrough analysis method.
