Deep water and subsalt plays are the two hottest exploration frontiers in the Gulf of Mexico and searching for structures below the salt in waters thousands of feet deep is the most exciting play with the greatest potential for reward vs. the risk.

In the mid-1990s, Arco International reviewed a farm-out proposal from Enterprise Oil for drilling on a block held by Enterprise in the Romanian Black Sea. Enterprise already had completed a seismic program and had mapped a variety of structures on the block.

Everyone knows Greenland has oil. But the exploration areas are so frontier they make Dodge City look like the middle of Manhattan, and so far no one has caught a glimpse of commercial Greenland production. So who will be first?

Field Seminar
Lisbon, Portugal
Tuesday, 20 June 2023, 8:00 a.m.–5:00 p.m.

Come along on this 1-day field seminar and tour outcrops in the Serra de Montejunto, just north of Lisbon and on the coast from Porto Novo to Paimogo. Instructors: Ricardo Pereira, GeoBioTec - Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa. Gil Machado, ChronSurveys Lda & Instituto Dom Luiz Fees: €190 - Local VAT applicable Limit: 20 Participants Includes: Ground Transportation Snacks and Refreshments Lunch and Dinner Guidebook Departure Time/Location 20 June 2023 8:30am Hotel Dom Pedro Note:Transportation to start point is not included in the costs of this trip. Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes. Aims To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants. About the Field Trip The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the field trip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.

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.
