Method and apparatus for installing electronic equipment below soft earth surface layer
First Claim
1. A method for installing a seismic instrument below the surface of the earth, the method comprising:
- drilling a deep borehole in the earth;
attaching the seismic instrument to a pipe string;
inserting the pipe string into the deep borehole so that the pipe string extends nearly to the bottom of the deep borehole; and
cementing the pipe string and the seismic instrument in the deep borehole by pumping concrete into the deep borehole through the inside of the pipe string so that the concrete fills the inside of the pipe string and flows out a hole at the bottom of the pipe string and up the borehole and around the seismic instrument.

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. 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 a Z-direction; and a housing for the geophone components which is permanently fixed in a borehole.

4. A method for installing an instrument below the surface of the earth, the method comprising:
-
drilling a deep borehole in the earth;
attaching the instrument to a pipe string having an upper portion and a lower portion, the instrument being attached to the lower portion of the pipe string;
inserting the pipe string into the deep borehole;
fixing the lower portion of the pipe string and the instrument in the deep borehole;
detaching the upper portion of the pipe string; and
covering the lower portion of the pipe string and the borehole over with earth to insulate the instrument from vibrations generated at and above the surface of the earth.
