ABSTRACT:
What is disclosed is an improvement in a multi-level geophone sonde installation for VSP which includes a well penetrating subterranean formations; surface source for generating and inputting vibrational wave energy; a plurality of geophone sondes with a plurality of detachable geophone sondes disposed in the well with an uppermost sonde and at least a plurality of other lower sondes at predetermined spacings for receiving vibrational wave energy arrival and generating the data indicative thereof; and conductors for getting to the earth's surface a record of the vibrational wave energy arrival data. The cable has a greater width than thickness and is rigid because it is formed in a plurality of vertebrae type formations so that it is self supporting or load bearing. Moreover, the rectangular cable reduces the twist of the cable. The cable has at least two longitudinal load-bearing cables for bearing the entire load of the plurality of geophone sondes and a plurality of longitudinal conductors operationally connectable to the geophone sondes so as to carry to the earth's surface signals indicative of the vibrational wave energy arrival data; and a holder for holding the cable at least adjacent the upper sonde and adapted for holding the entire weight of all the sondes.
