<!-- DAYSLIMIT: 10000--><!-- RecordType: Article--><!-- Description: Over the past 10 years, tight oil boosted the United States back to world prominence in crude oil production. Today’s projections tie future U.S. production levels to continued strength in tight oil output, especially from the Permian Basin. Considering the importance of unconventional oil plays in the overall U.S. production picture, it’s useful to examine the outlook for tight oil. And in the Permian Basin, that outlook isn’t as bright as previously thought.--><!-- NOHTML: --><!--ASDF-1/1/1999 12:00:00 AM-->

Such noise, if not tackled appropriately, prevents their accurate imaging. Small-scale geologic features such as thin channels, or subtle faults, etc. might not be seen clearly in the presence of noise. Similarly, seismic attributes generated on noise-contaminated data are seen as compromised on their quality, and hence their interpretation. Noise reduction techniques have been developed for poststack and prestack seismic data and are implemented wherever appropriate for enhancing the signal-to-noise ratio and achieving the goals set for reservoir characterization exercises.--><!-- NOHTML: --><!--ASDF-1/1/1999 12:00:00 AM-->
