Permeability Prediction Method for Unconsolidated Heavy-Oil Reservoir during Cold Production

Abstract

Abstract: Based on rock mechanical principles, integrated with the performance of heavy-oil cold production, the permeability changes of unconsolidated sandstone reservoirs with oil production rate and sand production rate are studied under the isothermal conditions. The quantitative permeability prediction model is developed for the heavy-oil cold production. This provides a basis for study of variation of oil production rate during cold production with sand control.

Key words: heavy oil reservoir, sand control, cold production, permeability, prediction
