P-Wave Attenuation – a Plausible Seismic Attribute to Detect Oil and Gas in Venezuela

B-25 P-WAVE ATTENUATION – A PLAUSIBLE SEISMIC ATTRIBUTE TO DETECT OIL AND GAS IN VENEZUELA SUMMARY 1 Two 3D field examples from Venezuela about using P-wave attenuation as a plausible seismic attribute for detecting pay zones are shown. First example is from a 3D pilot project in Eastern Venezuelan Basin oriented to improve the image of a deep Miocene oil-prospective turbiditic sandstone reservoir (pay) using RMS P-wave attenuation. It represents a challenge because the structural and stratigraphic complexity in this area and poor well control (a single well W-5). The result analysis shows that P-wave attenuation is more sensitive to
