It is a little over 25 years since the Iagifu 2-X well drilled by Niugini Gulf Oil discovered Papua New Guinea’s first commercial oil field – the Kutubu field, which was put into production in 1992 by Chevron Niugini Pty Ltd. after they acquired the assets of Gulf Oil.

Everyone in Houston lives within a few miles of a bayou. Some people think of them as permanent, but the bayous are constantly changing, especially during high water events like Hurricane Harvey. This trip is a 2.5 mile walk down a section of Buffalo Bayou where we will look at the archives of past storms and discuss what to do for future storms.

DL Abstract

Engineering of wind farms, development of carbon sequestration projects in shelfal waters, the proliferation of communication cables that connect the world, all of these things suggest that it is time to re-examine what we know about shelf processes both updip-to-downdip and along shoreline, and the influence of shelf processes on erosion and transport of sediments.

DL Abstract

As oil and gas exploration and production occur in deeper basins and more complex geologic settings, accurate characterization and modeling of reservoirs to improve estimated ultimate recovery (EUR) prediction, optimize well placement and maximize recovery become paramount. Existing technologies for reservoir characterization and modeling have proven inadequate for delivering detailed 3D predictions of reservoir architecture, connectivity and rock quality at scales that impact subsurface flow patterns and reservoir performance. Because of the gap between the geophysical and geologic data available (seismic, well logs, cores) and the data needed to model rock heterogeneities at the reservoir scale, constraints from external analog systems are needed. Existing stratigraphic concepts and deposition models are mostly empirical and seldom provide quantitative constraints on fine-scale reservoir heterogeneity. Current reservoir modeling tools are challenged to accurately replicate complex, nonstationary, rock heterogeneity patterns that control connectivity, such as shale layers that serve as flow baffles and barriers.

VG Abstract

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.
