This paper provides an easy-to-use procedure by which engineers and corporate planners can determine the economic limit for non-EOR projects in Alberta. The economic limit in this study is defined as the minimum average daily-oil-production rate needed to break even on a before- and/or after-income-tax basis. The economic limit for a single well, for a unit, and/or for a project can be determined by the procedure. The major advantage of this procedure is that it allows reservoir and production engineers to estimate economic limits quickly and accurately without the use of expensive economic models.
