EOR Potential of Naturally Fractured Supercritical Fluid Field
Authors L. Kollbotn, K. Khan, R. Berenblyum, L. Surguchev and C. AlvaresB21 EOR Potential of Naturally Fractured Supercritical Fluid Field K. Khan (PDVSA Oriente) R. Berenblyum (International Research Institute of Stavanger) L. Kollbotn* (International Research Institute of Stavanger) L. Surguchev (International Research Institute of Stavanger) & C. Alvares (INTEVEP PDVSA) SUMMARY The Orocual field operated by PDVSA is situated in the North Monagas region in eastern Venezuela. The main reservoir is naturally fractured sandstone containing supercritical fluid with composition varying from light gas/condensate at the top to moderately light oil at the bottom. The results of EOR potential evaluations for this field will be presented in this paper. The development of

Using Streamline Simulation for Advanced Reservoir Management
Authors M. Thiele and R.P. BatyckyB22 Using Streamline Simulation for Advanced Reservoir Management M. Thiele* (StreamSim Technologies) & R.P. Batycky (Streamsim Technologies) SUMMARY Streamline-based flow simulation (SL) is an effective and complementary technology to more traditional flow modeling approaches such as finite differences (FD). This is because streamline-based flow simulation is particularly efficient in solving large geologically complex and heterogeneous systems where fluid flow is dictated by well positions and rates rock properties (permeability porosity and fault distributions) fluid mobility (phase relative permeabilities and viscosities) and gravity. These are the class of problems more traditional modeling techniques have difficulties with. For waterflooding and EOR modeling

Application of IOR Methods on “Lukoil – West Siberia”
Authors K. Fedorov, M.R. Sadikov, N.E. Pavlov and M.F. PecherkinB23 Application of IOR Methods on “Lukoil – West Siberia” K. Fedorov* (Tyumen Research Center of "KogalymNIPIneft" Ltd) M.R. Sadikov (LUKOIL-West Siberia) N.E. Pavlov (Tyumen Research Center of "KogalymNIPIneft" Ltd) & M.F. Pecherkin (Tyumen Research Center of "KogalymNIPIneft" Ltd) SUMMARY The presentation briefly describes the main features of oil production on “LUKOIL –West Siberia” ltd operated fields. The complex IOR program was adopted and is realized by the operator. It includes horizontal and additional branches drilling hydraulic fracturing to maintain production on the mature fields large number of chemical treatments to decrease water production. The main operated fields have large

Monitoring of Reservoir Fluids Movement Based on Time-Lapse Microgravity Observations
By J. MrlinaB24 Monitoring of Reservoir Fluids Movement Based on Time-Lapse Microgravity Observations J. Mrlina* (Geophysical Institute ASCR) SUMMARY Monitoring of fluids in reservoirs has become an essential tool for the control of the development of hydrocarbon fields. Repeated microgravity measurements can determine especially gas-water or gas-oil contact displacement in time. Gravity modelling was performed to test such gravity monitoring effectiveness in case of gas storage and various cases of gas-water movement in reservoirs (pumping water-flooding etc.). The size of the gassaturated part of a reservoir sequence was changed in various directions as well as depth porosity and density contrasts between fluids.

Integrated 3D Seismic, Petrophysical Data of the Sarvak Formation, Sirri District in the Persian Gulf
By A. BashariP01 Integrated 3D Seismic Petrophysical Data of the Sarvak Formation Sirri District in the Persian Gulf A. Bashari* (Irannian Offshore Oil Company) SUMMARY Sirri district forms part of vast sedimentary area located between: The Qatar uplift in the west. The mio-geosyncline of the Zagross in the north. The Omanides geosyncline in the south east. To the south this sedimentary extends to the Rub Alkali desert. The study of the Middle- Late Cretaceous contains Mishrif Khatiyah and Mauddud members which called Sarvak (equivalent to Cenomanian of Middle Cretaceous) and Late Cretaceous formations contains Laffan Ilam and Gurpi. Among them the Mishrif

Sequence Stratigraphy and Characterization over Upper Surmeh (Arab) Formation Integrated with Petrophysical Evaluation in Reshada
By S. SohrabiP02 Sequence Stratigraphy and Characterization over Upper Surmeh (Arab) Formation Integrated with Petrophysical Evaluation in Reshada S. Sohrabi* (National Iranian Offshore Oil Company) SUMMARY The upper jurassic Surmeh(Arab) Formation in Block R in Iranian territorial Reshadat field in the Persian Gulf subdivided into the A A1 B C and D members is overlain by Hith formation and underlain by the Darb and Diyab formations. Typically the Darb and Diyab formations are potential source rocks the Arab members are reservoirs and the Hith is an extensive Seal. The Hith formation is unconformably overlain by lower Cretaceous limestones and Dolomites of the

IOR with Offshoots Application
Authors N.A. Cheremisin, A.A. Klimov, P.A. Efimov and R.A. BulatovP03 IOR with Offshoots Application N.A. Cheremisin* (SurgutNefteGaz) A.A. Klimov (SurgutNefteGaz) P.A. Efimov (SurgutNefteGaz) & R.A. Bulatov (SurgutNefteGaz) SUMMARY Offshoots application is universal IOR and stimulation of production method. It is effective during various development stages and allows solving a problem of remaining reserves recovery in interwell space nondraining because of limited stimulation radius of physicochemical and hydrodynamic advanced recovery methods. Moreover sidehole drilling allows: to realize replacing of simulation zones regulate displacement front and rehabilitate damaged low producing and drowned well stock. The especial problem for OJSC Sugrutneftegaz is increase development efficiency of oil-and-gas fields containing about 25.5% of
