Abstract
Various embodiments include nuclear magnetic resonance (MR) sensor array systems and methods are disclosed. One such system includes a downhole casing having at least one MR sensor array peripherally coupled to an outside of the casing. At least one MR sensor array can include an MR sensor configured to monitor a cement/fluid mix composition while the cement is setting.
Claims22
A sensor system, comprising
- a downhole casing comprising a support arm peripherally coupled to an outside of the casing, and extending from the casing, the support arm comprising a magnetic resonance (MR) sensor spaced apart from the casing along the support arm and embeddable in a cement/fluid mix composition in an annulus external to the downhole casing and operable to monitor the cement/fluid mix composition.
A borehole data transmission system, comprising:
- a downhole casing;
- a support arm coupled to an exterior of the downhole casing and extending from the casing, the support arm comprising a magnetic resonance (MR) sensor array, each MR sensor of the MR sensor array spaced apart from the casing along the support arm and embeddable in a cement/fluid mix composition in an annulus external to the downhole casing and operable to monitor the cement/fluid mix composition;
- and
- a sensor data transmission circuit coupled to the MR sensor array and configured to acquire sensor data from the MR sensor array and to transmit the sensor data.

A method for creating a sensor system, the method comprising:
- drilling a borehole into a geological formation;
- inserting a downhole casing into the borehole, wherein the casing comprises a support arm peripherally coupled to an exterior of the downhole casing and extending from the casing, the support comprising a magnetic resonance (MR) sensor array, each MR sensor of the MR sensor array spaced apart from the casing along the support arm and embeddable in a cement/fluid mix composition in an annulus external to the downhole casing and configured to monitor the cement/fluid mix composition;
- and
- injecting the cement/fluid mixture between the geological formation and the downhole casing.
