Maintaining maximum well delivery
Oil and gas reservoirs with a high degree of rock heterogeneity created through complex depositional environments, diagenetic or structural overprint, demand well completion solutions enabling response to changing reservoir conditions over the life of well to maintain maximum well delivery.
A key distinction between more conventional lower completion solutions and the Flex-Well® is the ability to deliver compartmentalized and controlled flow to TD regardless of the lateral length, the flow being regulated by Welltec Flow Valves (WFVTM) with Dual or with Multi Position.
The WFV with Multi Position provides the operator with the option of varying the differential pressure across the rock interface of each zone to balance out the difference in reservoir permeability. The Flex-Well will not only balance out heel toe effects but also control expected (or unexpected) permeability variance, along with water or gas breakthrough.
