A010 Canadian Arctic - Perspectives for the Petroleum Industry D. Evoy* (Petro-Canada) SUMMARY The oil and gas prospectivity of the Canadian Arctic has been demonstrated through exploration dating back to the 1960s; resources in the order of 20 Tcf of gas and 1.5 Bbbls of oil have been identified. However there has been no gas production to date and only a modest amount of oil has been produced. The Mackenzie Valley Pipeline currently under regulatory review is the proposed transportation route for development from the Mackenzie Delta / Beaufort Sea. More preliminary is the concept of LNG shipment from the

A012 Opportunities & Challenges Working in a "Arctic" Environment Offshore Sakhalin M. Gunningham* (Sakhalin Energy Investment Company) SUMMARY Sakhalin Energy is currently developing 3 oil and gas fields offshore Sakhalin Island off the east coast of mainland Russia. This is a challenging area for exploration and development with potentially billions of barrels of oil and gas. The key problem is that in the winter drifting sea ice several meters thick heavy snow and temperatures down to minus 40°C all contribute to Arctic type conditions. Under these conditions the offshore developments use the latest technology with concrete gravity based platforms which

A014 North Caspian Sea - An Ice Design Strategy D. Mayne* (AGIP KCO) SUMMARY This paper is focused on developing and implementing a strategy for development of the North Caspian Sea. Specific data needs are identified for Engineering Operations and other areas of the development. Costing of designs are tied back to an overall strategy to determine the motivation for design criteria refinement. Specific field data gathering activities are discussed in light of design criteria needs apparatus development data gathering and processing. Winter logistics and operational challenges are discussed. EAGE 69 th Conference & Exhibition — London UK 11 -

A018 Exploration for Gas Hydrates Based on Seismic Information – With Examples from Northern Gulf of Mexico J. Dai* (Schlumberger) & N. Dutta (Schlumberger) SUMMARY A five-step integrated workflow is developed to delineate shallow gas hydrates using seismic information. We applied the workflow and estimated gas hydrate saturations in two study areas in the northern deepwater Gulf of Mexico. Due to lack of hard data (well control) for the shallow seismic data our predictions used analogue models based on geologic interpretation seismic inversion and the basic principles of rock physics. To examine our predictions we analyzed the hydrate from the

A020 Prestack Stochastic Seismic Inversion of the Brenda Field G.J. Hicks* (Earthworks Environment & Resources) & A.M. Francis (Earthworks Environment & Resources) SUMMARY Joint AI-GI stochastic seismic inversion was performed for 100 pairs of equi-probable AI-GI realizations over the Brenda field which is located in block 15 in the North Sea. Stochastic inversion enables the possible variability in impedance and hence the uncertainty in lithology and fluid classification to be explored. These can be represented using probability and connected probability volumes calculated using joint AI-GI thresholds. EAGE 69 th Conference & Exhibition — London UK 11 - 14 June 2007

A022 Fractal Behavior of Fractures Derived from Seismic and FMI Data H. Trappe* (TEEC) H. Endres (TEEC RWTH Aachen) P. Thierer (TEEC) T. Lohr (GFZ Potsdam) C.M. Krawczyk (GFZ Potsdam) D.C. Tanner (GZG University Goettingen) O. Oncken (GFZ Potsdam) & P.A. Kukla (RWTH Aachen) SUMMARY This study is part of a larger research project. The results presented are from an area located east of the city Bremen where gas is produced from a deep Rotliegend sandstone reservoir. Faults fractures and associated deformation bands at reservoir depth have an important influence to the productivity of the gas field as fractures are

A024 Nile Delta Reservoir Case Study Using a Novel Broad Band Pre–Stack Seismic Inversion to Rock Properties Technique M.E. Smith* (Geotrace Technologies Inc.) SUMMARY Exploration for hydrocarbons within a concession located onshore in the Nile Delta Egypt has been ongoing for several years however so far has not afforded any significant discoveries. A pre-stack seismic inversion to rock properties procedure using a novel technique to provide broad bandwidth has provided increased understanding of the lithology and highlighted potential reservoir targets. EAGE 69 th Conference & Exhibition — London UK 11 - 14 June 2007 INTRODUCTION Exploration for hydrocarbons within an
