1. A reaction mass seismic source configured to advance through and operate in a non-vertical underground casing, the seismic source comprising:
- a base plate;
a reaction mass located above the base plate to press the base plate toward a wall of the non-vertical underground casing; and
a flextensional element located between the reaction mass and the base plate and configured to generate seismic waves underground when actuated.

Abstract
A reaction mass seismic survey source that is located in an underground casing. The seismic source includes a non-planar base plate; a reaction mass located on the non-planar base plate; and a flextensional element housed in a recess of the reaction mass and configured to vibrate the non-planar base plate when actuated, to generate seismic waves underground.

17. A method for generating seismic waves in a non-vertical borehole, the method comprising:
-
positioning a source element inside the non-vertical borehole, with a reaction mass of the source element remaining over a base plate thereof; extending a coupling element to push the base plate against a wall of the borehole; actuating a flextensional element located in a recess inside the reaction mass, the recess opening toward the base plate; and generating the seismic waves in the base plate by the actuated flextensional element. - View Dependent Claims (18, 19, 20)
