Abstract
A method for flowing a fluid from and/or to a subsurface formation includes disposing a main production tubular in a main borehole penetrating the subsurface formation, the main production tubular being coupled to a shunt assembly, the shunt assembly defining an opening oriented and biased in a desired direction for a lateral borehole penetrating the subsurface formation and having a shunt tube that bypasses the opening. The method also includes drilling the lateral borehole through the opening in the shunt assembly and installing a completion having a lateral production tubular coupled to a completion device in the lateral borehole through the opening. The method further incudes flowing the fluid from the subsurface formation to the shunt tube and/or from the shunt tube to the subsurface formation.
