Abstract

A geological formation tester tool (100) comprises a pulse generator (114), for generating a pulsed pressure waveform in a geological formation, wherein the pulsed pressure waveform is created about a first center frequency and wherein the pulse generator includes means for varying the center frequency at least one receiver probe (110), the or each receiver probe spaced apart a predetermined distance from the pulse generator and in contact with the geological formation; and at each receiver probe, a sensor (118) operably connected to the or each receiver probe for sensing a first arrival time at each receiver probe, of the pulsed pressure waveform.
A method of determining properties of a geological formation comprises: providing a downhole tool (100) having a pulse generator (114) and at least one receiver probe (110), the or each receiver probe spaced apart a predetermined distance from the pulse generator; generating a pulsed pressure waveform in the geological formation with the pulse generator; wherein the pulsed pressure waveform is created about a first center frequency and wherein the center frequency is variable sensing, at the receiver probe, a first arrival time of the pulsed pressure waveform; and determining the velocity of the pulsed pressure waveform.
