Several papers have been recently published1,2,3,4,5 discussing the process of air injection for light oil recovery and describing the criteria for a successful project. The performance of some light oil air injection field projects has also been discussed in these papers.2,5 However, the economics of this process have never been fully addressed before. This paper discusses the economics of a successful on-going project, the Medicine Pole Hills Unit (MPHU, ND), and a new project underway at West Hackberry, LA. The economics of air injection in low pressure fault blocks for repositioning and producing the oil rim are discussed as well.
