Abstract: A horseshoe lateral is drilled having two substantially parallel lateral sections connected with a horseshoe section. The horseshoe section may be obtained by steering a drill bit within a first plane over an in-plane angle of about 180°, and then continuing drilling along a straight path. A second lateral well system may drilled from a second borehole section, to create an additional lateral section interdigitally arranged between the previous two substantially parallel lateral sections.
