  • Method for determining a water intake profile in an injection well
    Patent number: 10174612
    Abstract: A first water injection into an injection well is carried out followed by a first shut-in of the injection well. A second water injection is carried out, a volume of the injected water exceeds several times a volume of water in the well in an intake interval. Then there is a second shut-in of the injection well, and during the second shut-in transient temperature profiles are registered within the intake interval by temperature sensors. Then a third water injection step is carried out and at an initial stage of the third injection transient temperature profiles in the intake interval are registered using the temperature sensors. The transient temperature profiles registered during the second shut-in period are analyzed and intake zone boundaries are determined. The transient temperature profiles registered at the initial stage of the third water injection are analyzed and a water intake profile is determined.
