Class Information
Number: 166/313
Name: Wells > Processes > Parallel string or multiple completion well
Description: A process comprising (1) the use of plural well conduits which extend from the ground surface substantially to or past a producing formation, the conduits being positioned side by side rather than one within the other, or (2) producing fluid from vertically spaced zones in the well.
