Two wells drilled from one surface bore with downhole splitter

The use of a downhole splitter allows oil well drillers to drill two cased wells from one well bore. The downhole splitter can be used for subsea completions, offshore platforms, offshore exploitation and delineation wells, as well as in environmentally sensitive onshore areas. The downhole splitter system was developed in Apr 1992 and tested in Wyoming. A detailed analysis of how the downhole splitter works and performed during field tests is provided.
A downhole multiwell drilling template, called a downhole splitter, allows two wells to be drilled, cased, and completed from one well bore. After completion, each well can be produced, serviced, [...]
