Abstract
The present disclosure generally relates to oilfield equipment and, in particular, to downhole tools, and related systems and methods for characterizing flow in a wellbore. More particularly, the present disclosure relates to methods and systems for obtaining flow data for evaluation of production profiles of wellbores. A system may be provided that comprises a work string, an external support device secured to an exterior of the work string, and at least one data collection device coupled to the external support device.
Claims20
An apparatus for flow measurement in a wellbore, comprising:
- an external support device comprising:
- a body, wherein the body defines a central opening for receiving a work string;
- and
- stabilizers that extend outwardly from an outer surface of the body;
- and
- at least one flow sensor coupled to the body operable to measure annular flow;
- a memory module carried by the external support device, wherein the memory module is coupled to the external support device for storing measurements of the annular flow from the at least one flow sensor;
- and
- a battery module carried by the external support device, wherein the battery module is coupled to the external support device for supplying power.
A system for flow measurement in a wellbore, comprising:
- a work string;
- a plurality of apparatuses secured to the work string at spaced apart locations, wherein each of the plurality of apparatuses comprises:
- an external support device comprising:
- a body, wherein the body defines a central opening through which the work string extends;
- and
- stabilizers that extend outwardly from an outer surface of the body;
- and
- at least one flow sensor coupled to the body operable to measure annular flow between the work string and a larger conduit or a wellbore wall;
- a memory module carried by the external support device, wherein the memory module is coupled to the external support device for storing measurements of the annular flow from the at least one flow sensor;
- and
- a battery module carried by the external support device, wherein the battery module is coupled to the external support device for supplying power.
A method of flow measurement in a wellbore, comprising:
- coupling an external support device to a portion of a work string, wherein the external support device carries at least one data collection device on the work string;
- running the work string into the wellbore to deploy the external support device in the wellbore at a target depth;
- and
- obtaining annular flow data with the data collection device in the wellbore with respect to annular flow between the work string and a larger conduit or a wellbore wall, wherein the annular flow data is obtained while the external support device is held at the target depth.
