Should We Waterflood Low Permeable Reservoirs?

Abstract

The aim of work is to ensure that it is possible to realize effective water injection system for low permeable reservoir with hard-to-recover deposits and an average permeability less than 1 mD. The results of oil field pilot works and computer modelling are shown and compared. The novelty of the work are rare enough field experiments in water injection system organization in low permeability reservoirs and injection system full comprehensive studding. Some empirical correlations between the values of permeability, heterogeneity, sweep efficiency and injection effectiveness for different well completion types will help reservoir engineers to select the best well pattern and to decide do we need any injection or not without labor intensive actions.
