Abstract (en)
[origin: EP1584783A1] A method of providing telemetry from downhole to a surface operator comprises: (a) providing a transmitter unit in a downhole structure; (b) providing a downhole tool having a non-acoustic receiver unit, data sensors, a microprocessor, and releasably storing a plurality of non-acoustic transmitter units; (c) moving the downhole tool in close enough proximity to the downhole structure so that the non-acoustic receiver unit can receive the non-acoustic signal transmitted by the non-acoustic transmitter unit; (d) writing data acquired from the data sensors to one of the plurality of non-acoustic transmitter units, the data written by the microprocessor; (e) releasing the one of the plurality of non-acoustic transmitter units; and (f) returning the one of the plurality of non-acoustic transmitter units to the surface. <IMAGE>
