Geology-guided reconditioning of Previous HitseismicNext Hit Previous HitdataNext Hit is the key to improving extraction of relevant geologic information Previous HitfromNext Hit three-dimensional (Previous Hit3-DNext Hit) Previous HitdataNext Hit volumes. In the Fullerton Clear Fork reservoir, the most convenient and useful tools for Previous HitdataNext Hit reconditioning are phase shifting and high-frequency enhancement. A simple Previous HitseismicNext Hit phase rotation (to 90deg) reconditions Previous HitseismicNext Hit Previous HitdataNext Hit for impedance representation, roughly linking Previous HitseismicNext Hit amplitude directly to log lithology and porosity and making stratigraphic correlation more accurate. High-frequency enhancement raises the dominant frequency of Previous Hit3-DNext Hit Previous HitseismicNext Hit Previous HitdataNext Hit Previous HitfromNext Hit 30 to 50 Hz, improving Previous HitseismicNext Hit resolution without significantly deteriorating signal-to-noise ratio. More accurate and finer scale Previous HitseismicNext Hit mapping of reservoir parameters is achieved Previous HitfromNext Hit model-based progressive Previous HitinversionNext Hit that seamlessly integrates geologic interpretation of well-derived Previous HitseismicNext Hit Previous HitdataNext Hit and model-based Previous HitseismicNext Hit Previous HitinversionNext Hit for high-resolution (2 ft [0.6 m]) impedance models.
