Abstract

This paper presents the results of a practical technique to determine pref-erential flow trends in a reservoir. The technique is a combination of reser-voir geology, tracer data, and Spearman rank correlation coefficient analysis of injection/production rate data. The Spearman analysis, in particular, will prove to be important because it appears to be insightful and uses data that are prevalent when other data are nonexistent. The technique is applied to the North Buck Draw field, Campbell County, Wyoming.

This work provides guidelines to assess information about reservoir continuity in interwell regions from widely available measurements of production and injection rates at existing wells. When successfully applied, the information gained can contribute to both the daily reservoir management and the future design, control, and interpretation of subsequent projects in the reservoir, without the need for additional data. As with other techniques, however, the method gives the most confidence when corroborated by other procedures.
