The development, analysis, and evaluation of type curve matching techniques for lenticular gas bearing formations are presented. The type curves are generated using a three dimensional, single phase, transient reservoir simulator modified to take into account lenticular sand lenses and hydraulically created fractures. The gas bearing sand lenses are assumed to be randomly distributed in orientation and space throughout the formation. Type curves are generated for an unfractured formation and vertically fractured formation with finite conductivity. Assuming different sand lense fractions, type curves are generated and compared with type curves developed for continuous (so called blanket) sand formations. The results of this comparative analysis indicates that the type curves for lenticular formations are significantly different from those of the blanket sand case that it may be possible to assess the degree of lenticularity of a given formation. Conclusions are drawn from the research presented and recommendations given concerning future research efforts.
