The paper describes an approach implemented for horizontal wells permanent monitoring to optimize development of carbonate reservoir based on the Prirazlomnoye oil field case study. Technology and results of production and injection wells hydrodynamic monitoring are shown in detail. The described hydrodynamic monitoring technology allowed confirming geological structure of the deposit, to identify pressure communication between injection and production wells and to improve efficiency of development system.

Summary Methods of field development of the Arctic shelf significantly different from oil land fields. The key features of the shelf fields are high costs and limited space to place the equipment. The field devepment plan should ensure high recovery factors with the relatively small number of production wells within the short period of time. The main factor to achieve the planned oil recovery factor is implementation of new technologies and approaches in the advanced well completion, well stimulation, and the use of full field reservoir model to take the best effective decisions in the part of the existing and project wells focused to increase the technological and economic efficiency of the project. This work is devoted to the comprehensive approach to field development based on hydrodynamic and tracer studies, generalization of field-geological information and geological and hydrodynamic stimulation.
