PROFESSIONAL DIVISION LUNCHTIME TALK DATE : Tuesday, April 16, 2002 TIME : 11:45 Hrs. VENUE : Kalimantan & Maluku Room, Lower Level Shangri-La JAKARTA Jln. Jendral Sudirman Kav 1 Jakarta 10220 SUBJECT : APPLYING STRUCTURAL EVOLUTION TO EVALUATION OF PETROLEUM SYSTEM SPEAKER : DR. Alan Gibbs, Midland Valley Exploration, Scotland BIOGRAPHY Dr Alan Gibbs has extensive experience in applying new concepts of structural evolution to petroleum systems in many basins around the world. He studied under John Ramsay in Imperial College, then completed a PhD study in West Greenland before taking up a lecturership in the University of London. He is a visiting professor in the University of London Royal Holloway College and has published extensively on the structural aspects of basin formation. In 1980 he joined the British National Oil Company as a structural geologist working in Reservoir Engineering, where he identified the role of transfer faults in reservoir compartmentalisation. In 1984, Dr. Gibbs founded Midland Valley as a centre of global excellence in software tools and consultancy for structural analysis. FUTURE TALKS Suggestions and volunteers for talks are always welcome. Topics should be relevant to exploration and production in Indonesia and/or be of interest to a wide range of disciplines.

Inversion, salt tectonics, or thrust faulting may lead to complex changes that become critical factors in risking the hydrocarbon system. To tackle this problem, it is necessary to integrate the structure model and its evolution through time with the development of both the sedimentary system and the migration and focusing of hydrocarbon fluids. Timing and changing geometric configuration are key issues, which can be tackled using an integrated workflow. This approach provides the ability to identify and assess risk in hydrocarbon systems and to generate multiple scenarios. It provides improved input into 2D and 3D basin modeling and allows the key system components to be integrated through deposition, faulting and folding, and migration of hydrocarbon fluids. 3D interpretations are used to generate a basin model that is back-stripped through time. This provides the basis for modeling sediment pathways and fluid migration fairways at each increment in time. As the model runs forwards through time, sediment accommodation space and sediment transfer are analysed. These factors are integrated with the depositional model, allowing subbasin spill-ways, stacking patterns, and migration of depocenters to be identified. Basin modeling then provides inputs to identify kitchen areas and to define timing of migration pathways and hydrocarbon charge. Fluid focusing and drainage cell analysis can then be evaluated, and models for fault seal or non-seal and reservoir compartmentalization can be investigated. Results of this analysis can be used to develop and condition detailed 2 or 3D basin models, or they may be applied directly to exploration decisions. This approach has worked successfully for projects in the North Sea, deep water Gulf of Mexico, Central and South America, North Africa and the Atlantic margin. It demonstrates clear benefits in significantly reducing work cycle times, and it provides technical results that differ significantly from conventional approaches that do not include effects of lateral displacements through time during structural evolution of the basin. ---- Gabung Milist Fogri, email ke fogri-request@xxxxxxxxxxxxx dengan subject subscribe Keluar Milist Fogri, email ke fogri-request@xxxxxxxxxxxxx dengan subject unsubscribe homepage : http://www.fogri.f2s.com Archieve : //www.freelists.org/archives/fogri/ -----
