Resolution Enhancement
High resolution – we want it because it is better! Digital cameras routinely deliver five or more megapixels these days and our televisions are almost all high-definition. Why should our seismic be any different, especially when our targets are the ones we could not see before? They may be deeper, smaller in areal extent, thinner or have less impedance contrast with surrounding beds, all of which call for better resolution.
Geotrace has been an industry leader for over a decade in improving resolution with its HFI® algorithm. Many successful wells have been drilled that would not have been otherwise because the interpreter could now detect subtle faults, resolve thin beds or see differences in reservoir quality using the higher resolution data. At first HFI® was just applied post-stack but over the last several years it has been increasingly used on gathers as input to pre-stack analysis such as AVO and, more recently, RockRes®, Geotrace’s inversion to rock properties.
We continually strive to update and improve the tools that we use and one result is our new algorithm, Bandwidth Extension (BE™) that goes the next step toward resolution. Not only does BE™ extend the high end of the spectrum like HFI® but it can also extend it downward, a huge advantage especially when going into pre-stack inversion. Please read more about each algorithm and view examples with the links on this page.
