Abstract: A proactive conformance method for a well includes selecting a well either in a completion phase or early in a production phase of the well and performing a conformance treatment on the well in the completion phase or early in the production phase. The conformance treatment preferably is performed before the well is completed (i.e., sometime during the completion phase between the well having been drilled and the well being placed in production), such as after running open hole logging or before setting casing. Another preferred aspect is the use of magnetic resonance imaging, such as using magnetic resonance imaging to analyze the well to determine where unwanted mobile fluid is in a reservoir intersected by the well. Such a well is completed in response to using the magnetic resonance imaging, including treating the well to confine at least part of the unwanted mobile fluid determined to be in the reservoir.
