Abstract
An example method for making downhole measurements may include positioning a tool with a conformable sensor within a pipe in a borehole in a subterranean formation, and generating a first electromagnetic signal using at least one of a plurality of transmitters of the conformable sensor. A first response to the first electromagnetic signal may be measured using at least one of a plurality of receivers of the conformable sensor. At least one of a scale parameter, a pipe parameter, and a stand-off distance between the conformable sensor and the pipe may be determined using the first response.
Claims18
A method for making downhole measurement, comprising:
- positioning a tool with a conformable sensor within a pipe in a borehole in a subterranean formation, wherein the conformable sensor is disposed on a material that conforms to a surface of the tool, wherein positioning the tool with the conformable sensor within the pipe in the borehole comprises extending a pad from the tool, the conformable sensor being coupled to the pad body such that the conformable sensor contacts the pipe by deforming to a shape of the pipe;
- generating a first electromagnetic signal using at least one of a plurality of transmitters of the conformable sensor;
- measuring a first response to the first electromagnetic signal using at least one of a plurality of receivers of the conformable sensor;
- and
- determining at least one of a scale parameter, a pipe parameter, and a stand-off distance between the conformable sensor and the pipe using the first response.
A system for making downhole measurement, comprising:
- a downhole tool disposed within a pipe;
- an extendable arm coupled to the downhole tool;
- a pad coupled to the extendable arm;
- a conformable sensor coupled to the pad of the extendable arm of the downhole tool, wherein the conformable sensor deforms to a shape of the pipe based on a tension of the extendable arm, and wherein the conformable sensor comprises:
- a flexible material that conforms to a surface of the downhole tool;
- a plurality of transmitters coupled to the flexible material;
- and
- a plurality of receivers coupled to the flexible material;
- a control unit comprising a processor and a memory device coupled to the processor, the memory device containing a set of instructions that, when executed by the processor, cause the processor to
- generate a first electromagnetic signal using at least one of the plurality of transmitters;
- measure a first response to the first electromagnetic signal using at least one of the plurality of receivers;
- and
- determine at least one of a scale parameter, a pipe parameter, and a stand-off distance between the conformable sensor and the pipe using the first response.
