Acoustic Logging Methods in Fractured and Porous Formations
Abstract: Abstract Formation fractures have significant importance in the rocks’ permeability of oil and gas reservoirs. In real conditions, the opening of vertical fractures exceeds the opening of horizontal fractures and the permeability of reservoirs in conditions of horizontal wells is higher than in vertical conditions. For the sonic log longitudinal waves, unlike the transverse waves, the attenuation rate strongly depends on the wave path direction. It is shown that the …
