Method of monitoring a mineral reservoir |
摘要 |
A method 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 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 instrument in the borehole. An instrument for receiving seismic data, the instrument comprising: a geophone component which operates in an X-direction; a geophone component which operates in an Y-direction; a geophone component which operates in an Z-direction; and a housing for the geophone components which is permanently fixed in a borehole.
