A completion system for use in a well includes a first completion section and a second section. The first completion section has a sand control assembly to prevent passage of particulates, a first inductive coupler portion, and a sensor positioned proximate to the sand control assembly that is electrically coupled to the first inductive coupler portion. The second section is deployable after installation of the first completion section. It includes a second inductive coupler portion to communicate with the first inductive coupler portion, to enable communication between the first completion section's sensor and another component coupled to the second section.

An apparatus that is usable with a well includes a first equipment section that includes a first inductive coupler and a second equipment section that includes a second inductive coupler. The second equipment section is adapted to be run downhole into the well after the first equipment section is run downhole into the well to engage the first equipment section. A mechanism of the apparatus indicates when the first inductive coupler is substantially aligned with the second inductive coupler.

To assemble a sensor array having plural sections, the sections of the sensor array are sealably attached, where the sections include sensors and cable segments. An inert gas is flowed through at least one inner fluid path inside the sensor array when the sections of the sensor array are being sealably attached.
