DUAL PURPOSE OBSERVATION AND PRODUCTION WELL

摘要

A method for producing hydrocarbons in a subterranean well useful for observing properties of one or more subterranean zones, includes the steps of: (a) installing a lower straddle packer in a vertical well bore below a junction with a lateral well section; (b) installing an upper straddle packer in a vertical well bore above the junction with the lateral well section; (c) conveying hydrocarbons from the from the lateral well to the surface with a tubing; (d) observing pressure information in at least one zone with a pressure gauge located in the vertical well bore below the lower straddle packer; and (e) obtaining information in the at least one zone with logging equipment run through the tubing. A sidetrack window may be installed in the tubing between the lower straddle packer and the upper straddle packer for providing access to the lateral well section.
