Laboratory Studies of Immiscible N₂ WAG Flooding for Low Permeability Reservoir of Ordos Basin

Abstract:

This paper presents experimental work that quantifies the effect of water-alternating-gas (WAG) variables on the immiscible N2 flooding process for low permeability reservoir of Ordos Basin. Many experiments were done with the sand-packed model under the formation condition. The results may be used to determine such parameters as injection pattern, WAG radio, and the number of WAG slugs. Analysis of the relative efficiency of each WAG slug is discussed.
