The observation of low frequency (2-4 Hz), low velocity (300 m/sec-400 m/sec so far noticed) and high amplitude over subsurface poro-fractured strata contains oil and gas is the main subject of our discussion (G.M. Goloshubin et al., 1993, Andika Perbawa et al.,2013 and G.K. Batta et al, 2014). The theory of seismic wave propagation cannot explain this phenomenon well enough. We developed a theory for possibility of hydrocarbon fluid wave which is responsible for low frequency, low velocity and high amplitude. Results of the theoretical research correspond to the data of field experiment. Low frequency is due to natural oscillation of hydrocarbon fluids at poro-fractured strata. Low velocity is due to abnormal pore pressure above hydrostatic. High amplitude is due to resonance phenomena with natural oscillation of hydrocarbon fluids. Utility of hydrocarbon fluid wave will confirm the hydrocarbon fluid presence in strata associating with abnormal high pore pressure gradient. It helps in prediction of depth, abnormal pore pressure above hydrostatic, Mud weight, Static Bottom Hole Pressure (SBHP) and average production rate per day.
