METHOD AND SYSTEM FOR RECIRCULATING FLUID IN A WELL SYSTEM

摘要

A method for recirculating fluid in a well system 10 includes drilling a first well bore 12 from a surface 14 to a subterranean zone, and drilling an articulated well bore 30 that is horizontally offset from the first well bore 12 at the surface 14 and that intersects the first well bore 12 at a junction proximate the subterranean zone. The method also includes drilling a drainage bore 40 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 40. The gas, water, and particles are received from the junction at the surface 14, 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.
