The present generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve 310 or a separate instrumentation sub. In one aspect, A method of using a downhole deployment valve (DDV) 310 in a wellbore 130, 120 extending to a first depth, the method comprising, assembling the DDV 310 as part of a tubular string, and a sensor configured to sense a parameter of the wellbore 130, 120 or a formation 248, running the tubular string into the wellbore 130, running a drill string 305 through the tubular string bore and the DDV 310 bore, drilling the wellbore to a second depth using the drill string 305; and receiving at least one acoustic wave 501, 503, 511, transmitted into a formation 248 from a seismic source 471 such as a seismic survey, with the sensor 362 while drilling the wellbore to the second depth. |
