Paper presented at the SEG International Exposition and Annual Meeting, September 15–20, 2019
Paper Number: SEG-2019-3214088
... ABSTRACT An ongoing challenge to seismic interpreters is to identify and extract heterogeneous seismic facies on data volumes that are continually increasing in size. Geometric, geomechanical, and spectral attributes help to extract key features but add to the number of data volumes...

Paper Number: SEG-2016-13954311
... ABSTRACT We present in this paper a methodology to use prestack seismic inversion results to constrain facies modeling in unconventional reservoirs. The fact that the exploitation of unconventional reservoirs typically relies on the use of large numbers of long, closely spaced, data poor...

... Conceptual facies models are vital for making sedimentologic and stratigraphic interpretations in data poor settings. The Panther Tongue Sandstone (PT) of Central Utah has been cited as a type example for river-dominated deltaic depositional systems since the 1990’s. However, several significant...
