Abstract
Official abstract text for this publication.
A packer deployed well wall monitoring or transceiver assembly. The assembly may be particularly suited for use with swellable packers wherein the sensor or transceiver is delivered in a manner that substantially avoids damage thereto. Furthermore, the pre-deployment configuration of the assembly may enhance the deployment and reliability of the sensor in terms of formation monitoring over time. The deployment of the packer provides the energy required for the sensor or transceiver to contact the well wall. The packer elastomeric material provides or can be enhanced to provide isolation of the sensor or transceivers from extraneous borehole disturbances improving their signal to noise characteristics.
First claim
Opening claim text (preview).
We claim: 1. A packer for disposing in a well at an oilfield, the packer comprising: a swellable elastomer structure disposed about an under-support structure; and a sensor configured to sense a condition exterior to the packer; a transmitter configured to transmit energy into a wall of the well, wherein the sensor and transmitter are disposed at an outer surface of the elastomer structure for contacting the wall of the well upon swelling deployment thereof; a telemetry line…
