Selecting optimal technology for wells completion in the oil rims of continental genesis on the example of layers PK1-3 of the Vostochno-Messoyakhskoye and Tazovskoye fields

Greater part of new gas-oil fields in Western Siberia are characterized by extensive gas caps, less oil net pay and underlying water saturated intervals. Determine the major criterion for successful release of application of autonomous inflow control devices (AICD) in objects of the Vostochno-Messoyakhskoye field and methodology of searching for candidate wells. This article presents experience of using AICD on the wells of the PK1-3 and MKH8-9 formations, and results of multiple-path simulation. The article describes features of simulation modeling of AICD such as initialization of multi-segment wells, creating virtual ICD and estimating of its parameters, as well as methods of history matching of AICD-wells. Efficiency of AICD depending on the geological and technological features: distance to GOC, OWC to well, spreading of permeability along near-wellbore formation, compartmentalization. To calculate influence of these parameters, multivariate calculations performed on synthetic hydrodynamic models. To determine optimum of AICD working and select candidate wells was calculated various geological and geophysical characteristics: depth of GOC and WOC, properties of fluids, heterogeneity of reservoir properties. Based on results of this research, optimal geological and geophysics conditions for wells of the "Vostochno-Messoyakhskoye" field were defined. Methods and outputs of this article can be used to solve same issues in similar formations and development schemes.
