Event Description
DRIVERS FOR RESERVOIR QUALITY, ENVIRONMENTS OF DEPOSITION AND ANALOGS
BY
Scott E Thornton, Department of Geology and Geophysics, The University of Sydney and DI International, Nicholas B. Harris, Department of Geology and Geological Engineering, Colorado School of Mines, Ann-Marie Scott, Roc Oil Company Limited, and Michael Dyer, DI International
The key to reaching an enlightened understanding of this complexity relies more on creative right brain thinking than left brain logic and data collecting. At present, discoveries made in the last several years have challenged our depositional models and the dogma that the carbonates and clastics are plagued by poor reservoir continuity and quality.
The reservoir's distribution and properties are a function of the depositional environment in large and small rift lakes in the early Cretaceous. Carbonate and clastic reservoir distribution and quality in lakes are controlled by rift geometry and orientation, lake depth and cross-section profile, wave climate and fetch, drainage patterns in the hinterland, entry points of clastics, lake salinity, local climate and cycles of lake level fluctuation. These drivers for understanding reservoir quality and continuity will be reviewed on first principles from our knowledge of recent and ancient deposits, as well as theoretical framing.
Field Analogs and regional data will be reviewed for the Santos, Campos and Reconcavo basins of Brazil as well as the Kwanza and Cabinda basins of Angola and basins in Gabon. Our global analog set for clastic and carbonate reservoirs is diverse enough that no two lacustrine basins are really alike. Our analog set for both recent and ancient lakes is also not as statistically significant as sets for other reservoirs.
Computer-driven global climate models for lakes in the present and past are much more difficult than those for marine and deltaic depositional environments, and have had limited success. An enlightened and more successful exploration campaign in these high-potential reservoirs will result from the understanding of these first principles. Exploration campaigns driven by only seismic interpretation and structural modeling may be prone to a lower rate of success if not tempered by a more sophisticated understanding of the drivers for these complex, and often excellent reservoirs.

Fugro Robertson’s technical experience, in projects ranging from regional and basin scale studies to prospect and field evaluations, has been gained in practically every hydrocarbon province in the world – the basis of a reputation trusted by a strong portfolio of clients, including international oil companies, national oil companies, government institutions and international finance agencies.
ION is a leading provider of geophysical technology, services, and solutions for the global oil & gas industry. ION - GX Technology offerings include: seismic data processing solutions, including state-of-the-art depth migration, reverse time migration, and full-wave imaging; regional basin-scale seismic programs comprising a global multi-client data library; software and services for survey design, geophysical analysis, and reservoir modeling; and seismic imaging programs encompassing survey planning, field acquisition, and final image rendering. Additional information is available at www.iongeo.com
GSI & DIGs will be displaying their MARIMBA ("Margins of the Atlantic Region, Integrated Multi-disciplinary Basin Analysis") study with a focus on West Africa.
Geochemical Solutions International, Inc. (GSI) was established in 1998 to provide the oil and gas industry geochemical technology for use in the exploration of natural hydrocarbon resources. With offices in Houston and Rio de Janeiro, GSI has conducted over 40 non-exclusive, multi-client projects in Brazil and elsewhere in Latin America, including regional, basin and field studies, surface geochemical surveys and integrated basin modeling. GSI, DIGS and GrizGeo have collaborated on numerous projects focused on the South Atlantic Marin since 2001.

DIGs (Dickson International Geosciences) was founded in 1998 in Houston, Texas by William Dickson, VP-Technology. DIGs has developed super-regional basin studies of Southeast Asia (SEATIGER), the Atlantic margins (CARUMBA, M2C) and, working with GSI, MARIMBA (Margins of the Atlantic Region Integrated Multi-disciplinary Basin Analysis). MARIMBA uses a 4G approach, integrating geology, geophysics and geochemistry in a GIS framework. MARIMBA is the successor product to BRIOS and SAMBA, the bases of our original 2005 AAPG poster demonstrating the existence and extent of a Santos Basin pre-salt source.

Biography
Scott is currently Manager, West Africa for DI International in Houston. Last year he was Manager, Northern Latin America working for Michael Dyer, VP Latin America, who has extensive experience on Brazil for many years at IHS Energy, prior to joining DI Internatioal. Scott has worked 25 years in international exploration for several companies and clients, with most of his experience at Unocal and Shell. He had a 10 year consulting career predominantly working on pre-salt and post-salt basins of Brazil and West Africa. The last two years of that consulting career were with Devon Energy mapping the pre-salt of offshore Kwanza Basin as well as regional and prospect-specific post-salt mapping of turbidites and marine carbonates in the Campos, Santos and Espirito Santo basins.
After Devon, Scott moved to Sydney, Australia with Roc Oil Company Limited. One of his projects was seismic facies mapping of potential Toca lacustrine carbonate reservoirs in onshore Cabinda, which resulted in a well. Scott has been responsible for acquiring or applying for acreage in Burma, Pakistan, NW China, Ecuador, Peru, Brazil, California and North Alaska.
Scott received his BA in Geology and Geophysics at the University of Wisconsin, Madison, his MS in Geological Sciences at Duke University and his PhD in Geology and Geophysics at the University of Southern California. He currently is also an Adjunct Professor at The University of Sydney. Scott taught 2 short courses while in Sydney on Introduction to Petroleum Systems as well as Lacustrine Petroleum Systems at the Petroleum Society of Australia, where many of his students were from the local universities as well as the industry.
