Abstract: This invention relates to a process for isolating one or more segments of a gravel packed well from other segments to treat the isolated segments and easily re-establish flow from the other segments after the treatment. The treatment includes techniques for enhancing or permanently blocking production from the isolated segment. The process includes the installation of a removable sealing element and a permeability poison that forms a fluid seal to prevent longitudinal fluid flow along the annular production space outside the tubular production pipe. With wireline or other low-cost wellbore workover systems, access is re-engaged with the secluded formation including removal of plugs and fluid seals within the tubular production pipe. The inventive process allows enhanced recovery of fluids by focusing treatments on problem areas without harming productive segments of the well.

Abstract: Methods and systems for depth and radial orientation detection are provided. Methods for determining the depth or radial orientation of one or more downhole components include the steps of providing a target mass and a using a detection device for detecting the depth and/or orientation of the target mass. In some cases, the target mass is initially nonradioactive and then, after installing the target mass downhole, it may be irradiated to form a relatively short-lived radioactive target mass, which may then be detected with a radiation detector. In this way, the target mass acts as a depth or radial orientation marker. Where the target mass is situated downhole in a known radial relationship to another downhole component, the radial orientation of the other downhole component may be deduced once the radial orientation of the target mass is determined. Advantages include higher accuracies and reduced health, safety, and environmental risks.
