Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
141 words
AN APPARATUS FOR LOGGING THE VELOCITY OF SEISMIC ENERGY WHICH INCLUDES A SONIC GENERATOR FOR GENERATING A CONTINUOUS SONIC WAVE, A SONIC RECEIVER FOR DETECTING A SONIC WAVE, MEANS CONNECTED TO SAID GENERATOR AND SAID RECEIVER FOR LOWERING SAID GENERATOR AND SAID RECEIVER SPACED APART IN A BORE HOLE WHEREBY SAID GENERATOR PROPAGATES A CONTINUOUS SONIC WAVE WHICH IS DETECTED AT SAID RECEIVER AFTER PASSING AS SEISMIC ENERGY IN THE SUBSURFACE FORMATION THROUGH WHICH SAID BORE HOLE EXTENDS, AND MEANS COUPLED TO SAID GENERATOR AND SAID RECEIVER RESPONSIVE TO THE PHASE OF SAID WAVE DETECTED AT SAID RECEIVER RELATIVE TO THE WAVE GENERATED BY SAID GENERATOR AND OPERABLE TO ALTER THE RELATIONSHIP BETWEEN THE FREQUENCY OF THE GENERATED WAVE AND THE SPACING OF SAID GENERATOR AND SAID RECEIVER WHEREBY SAID GENERATED WAVE AND SAID DETECTED WAVE ARE 180* OUT OF PHASE.
