  • Patent number: 6325161
    Abstract: A method and apparatus for monitoring production mineral reservoirs, the method comprising: permanently installing a geophone in a borehole; generating a first set of seismic waves; receiving a first set of seismic data with the geophone; recording the first set of data of said receiving a first set of seismic data; generating a second set of seismic waves after sufficient time has passed for conditions in the reservoir to have changed from the generating a first set of seismic waves; receiving a second set of seismic data with the geophone; and recording the second set of seismic data of said receiving a second set of seismic data. A method and apparatus for installing instruments below the surface of the earth, the method comprising: drilling a borehole with a drill apparatus inserting an instrument in the borehole; and permanently fixing the instruments in the borehole.
