A new research paper, recently  published in Geophysical Journal International,  led by G&G post graduate student Kelvin Amalokuw; with colleagues from the universities of Southampton and Edinburgh, and the British Geological Survey: Experimental studies have shown the ratio of P- to S-wave attenuation (Q¬s/Qp ratio) to be more sensitive to gas saturation than the ratio of P-… Read More Water saturation effects on elastic wave attenuation in porous rocks with aligned fractures
