ABSTRACT:
Apparatus and method for detecting varying flow velocity at differing points outside the casing in a wellbore are provided. The flow is detected by stationary temperature sensors inside the casing. Logging means, sensors left in the well with data storage, data telemetry to surface and downhole alarm systems are provided. Measurements are used for detecting lack of mechanical integrity of a wellbore, hydraulic fracture extent along a wellbore, vertical flow in a formation or other occurrences of non-uniform flow.
