Increasing the Accuracy of Production Allocation from Each Reservoir: Integrating TAML-1 Well Construction Technology and the Dynamic Quantum PLT Method in the Field NP

Abstract

One of the largest oil fields on the Yamal Peninsula, the Field NP is characterised by complex geological settings. Massive gas caps pose significant complications to the extraction of large oil reserves occurring immediately below them. In such conditions, new approaches are required to achieve economically viable production. This involves well construction based on a fundamentally new configuration and the use of new technologies. When drilling wells that penetrate more than one target reservoir, the legislation requires performance monitoring and separate production allocation for each reservoir. The article dwells on the first case of separate production allocation in a multilateral well completed with the TAML-1 solution. The well penetrates two reservoirs with different porosity and permeability, using the dynamic quantum PLT technology. The well was drilled taking into account the properties of the impermeable top of one of the reservoirs.
