Dr. Osareni (Chris) Ogiesoba, Research Scientist with the UT Bureau of Economic Geology
Presentation Summary
Dr. Ogiesoba will discuss results of an investigation conducted to determine hydrocarbon sweet spots distribution within the Campanian Taylor sandstone in Serbin field, covering 56 mi2 (~90 km2) and straddling parts of Lee, Bastrop, and Fayette Counties in southeast Texas. By integrating 3D-seismic-multiattribute analysis, neural network techniques, and core data, we demonstrate that (1) hydrocarbon sweet spots are laterally separated by mudstones and calcite- and quartz-cemented sandstones, (2) within the Taylor sandstones in Serbin field, porosity increases with depth, and (3) the Serbin field is separated into two areas: (i) a diagenetically altered, high-impedance, low-porosity rock area in the western section, and (ii) a low-impedance and relatively high-porosity sandstones area located in the eastern section.
Biography
Osareni (Chris) Ogiesoba is a Research Scientist with the Bureau of Economic Geology, Jackson School of Geosciences, The University of Texas at Austin. He holds a Ph.D. in earth and planetary sciences from McGill University, Canada, and M.Sc. in geophysics from Imperial College London, UK. Prior to joining the Bureau in 2007, Dr. Ogiesoba worked for Mobil for 19.5 years and was instrumental in the discovery more than 1 billion bbls of oil for Mobil. His research interests are in seismic interpretation, seismic attributes, inversion, and converted-wave seismic exploration. He is a member of SEG and AAPG.
