Claim:
1. A method for producing hydrocarbons in a subterranean well useful for observing properties of one or more subterranean zones, the subterranean well having a vertical well section a plurality of lateral well sections, the intersection of the vertical well section and each of the plurality of lateral well sections creating a plurality of junctions, the method comprising the steps of: (a) installing a lower straddle packer in the vertical well section below each of the plurality of junctions; (b) installing an upper straddle packer in the vertical well section above each of the plurality of junctions to create an isolation zone between the lower straddle packer and the upper straddle packer around each of the plurality junctions; (c) conveying hydrocarbons from the lateral well sections to the surface with a tubing; (d) observing pressure information in at least one measurement zone with a pressure gauge located in the vertical well section outside all of the isolation zones, so that the pressure gauge does not hinder production from the lateral well section; and (e) obtaining information in at least one zone with a logging equipment run through the tubing.
