Proxy model for a near well in a thin oil layer reservoir with high permeability

Abstract

This report describes the work performed in the project “Near well modelling”, under the NTNU IO centre. The work has been performed in close collaboration with FMC Technologies. Near well models based on first principles and Darcy’s law have been developed in the project. The models are developed in order to support fast generation of dynamic GOR values for use in production optimization. The main focus is oil fields with a thin layer of oil and a gas cap. The model has been verified by simulation and gas coning has been illustrated. Moreover, a model describing wells lying in the water zone under the oil layer has been developed. Simulations showing water and gas coning have been presented. Recommendations for further work have been presented. The main focus is model development for generation of dynamic GOR values, and possible incorporation in FMC Technologies software in the near future. This would also include further development of the near well models to be able to model up-coning of water, development of an estimation scheme for state estimation and a detailed study on the development of more simplified near well models by using black box techniques.
