Theoretical Dimensionless Breakthrough Time of a Horizontal Well in a Vertically-Stacked Two-Layered Reservoir System with Varying Architecture Part I: Letter ‘B’ Architecture, Edge Water Drive Mechanism

In this paper, which is Part I of a series, theoretical breakthrough times of different models of a crossflow two-layered reservoir having an architecture similar to letter ‘B’ and experiencing an edge water drive, with or without a top gas, are derived. The theoretical breakthrough times are based on dimensionless pressure distributions of each identified model.
