Abstract
A method for recirculating fluid in a well system includes drilling a first well bore from a surface to a subterranean zone, and drilling an articulated well bore that is horizontally offset from the first well bore at the surface and that intersects the first well bore at a junction proximate the subterranean zone. The method also includes drilling a drainage bore from the junction into the subterranean zone, and receiving gas, water and particles produced from the subterranean zone at the junction via the drainage bore. The gas, water, and particles are received from the junction at the surface, and the water is separated from the gas and the particles. The method also includes determining an amount of water to circulate, and recirculating a portion of the separated water according to this determination.
