Abstract: Methods and systems relate to recovering hydrocarbons from within formations in which hydrocarbon bearing reservoirs are separated from one another by a fluid flow obstructing natural stratum. Relative to the reservoirs, the stratum inhibits or blocks vertical fluid flow within the formation. Lateral bores divert from lengths of injector and producer wells along where extending in a horizontal direction. These bores pass upward through the formation to intersect the stratum and provide an array of fluid flow paths through the stratum. In a side direction perpendicular to the horizontal direction of the wells, the lateral bores from the injector well pass through the stratum inside of where the lateral bores from the producer well pass through stratum. Fluid communication established by the bores limits counter-current flow through the bores in processes that rely on techniques such as gravity drainage.
