In wells where economic production is being impaired by interzonal communication from nearby gas or water sources, traditional cement squeezing could damage production inflow.
In such cases, the Radial REED patented process reduces the cross-sectional area of the annulus above or below the producing interval without perforating or the injection of potential damaging sealants.
Often annular interzonal communication from above or below can impair oil production. Close proximity to the producing zone makes conventional perforating and squeeze operations risky and decrease casing integrity by putting more perforations in the casing in undesirable locations.
