ABSTRACT:
A splitter assembly10is positioned downhole within a conductor50for separating two or more tubular strings placed within the conductor. A splitter housing may include a first bore26and a second bore28for separating a first well from a second well, and a plug24positioned in one of the bores including a top face25sloping downwardly toward the other bore. One or more guide plates18secured to the splitter housing and positioned above the plug guide a bit or other tool toward one of the first bore and the second bore. The splitter housing10may be positioned along the conductor50after the conductor is jetted in place. According to the method, the plug in one of the bores is retrieved after a casing is run in one well, so that the second bit and the second casing will pass through the bore which previously included the plug.
