Oil rim reservoirs are the main assets for new oil production regions. The oil rim development is associated with significant challenges. Among these are the primary methods of reservoir penetration, long-term development under solution gas, gas cap and drive support, decision of effective gas usage (associated and gas-cap). The paper is concerned with basic elements of integrated development concept of Novoportovskoye field, which was involved in the development in 2016. This paper presents current development trends and prospects of experience replicating for other development projects with oil rims. The world experience analysis revealed that 50-70% of oil rim reserves are recovered by primary methods. The main criterion of primary oil recovery efficiency is the ratio between well productivity and well cost. On the other hand the project success depends on accepted development strategy, especially the gas injection duration for pressure maintenance and beginning gas transportation for selling. The one of the effective approaches of project management is an integrated modelling, which includes the calculation of the reservoir, wells and surface infrastructure models simultaneously.
