  • interfacial tension and spreading coefficient under reservoir conditions
    Fluid Phase Equilibria, 1998
    Co-Authors: Robert Amin, Terence N. Smith
    Abstract:

    The variation of interfacial tension (IFT) with temperature and pressure strongly influences the transport of the fluid in a reservoir. This makes the IFT probably the most important of the factors that make one-third of the total oil in place (in reservoir rock) un-recoverable by gas drive or water flooding [H.Y. Jennings Jr., G.H. Newman, The effect of temperature and pressure on the interfacial tension of water against methane-normal decane mixtures. SPE 1971, pp. 171–175]. Several models and correlations were used to calculate the measured data presented here. We have studied the applicability of four most commonly used IFT-correlations, those of Katz et al. [D.L. Katz, R.R. Monroe, R.P. Trainer, Surface tension of crude oils containing dissolved gases. AIME. Technical publications No. 1624, pp. 285–294.], Hough and Stegemeier [E.W. Hough, G.L Stegemeier, Correlation of surface and interfacial tension of light hydrocarbons in the critical region. SPEJ, December 1961, pp. 259–263.], Lee and Chien [S.T. Lee, M.C.H. Chien, A new Multicomponent surface Tension correlation based on scaling theory. SPE/DOE 12643 fourth symposium on EOR/Tulsa, OK, April 15–18.], and Pedersen et al. [K.S. Pedersen, F. Aage, P. Tomassen, properties of oils and natural gases. Gulf Publishing, 1989, pp. 196–207]. The experimental results from the three binary systems as well as the recombined crude oil system have shown that the IFT in the high pressure region (below saturation pressure) remains quite low despite large pressure decrements. This study was then extended to include measurements of the equilibrium interfacial for oil–brine, oil–gas and gas–brine at reservoir temperature and pressure over the range 250 to 3728 psia. The IFT were used to evaluate the spreading coefficient as a function of pressure at reservoir temperature. The viscosity and density of the oil and gas and brine phases were also measured over the same range of reservoir conditions.

  • Decommissioning Offshore Petroleum Fileds
    2015
    Co-Authors: Ruivo F.m., Morooka C.k.
    Abstract:

    Decommissioning offshore petroleum production activities have been progressively increasing the concern of the industry, government and distinct interest groups through the last years. There are at least two reasons for this sudden regard: first it is the maturing of several oil and gas fields around the world hi recent years; second, it is the growing impact of environmental concerns in international affairs.Although several works published address to some techniques and to potential problems/risks related to decommissioning of offshore oil and gas production installations, its operations (mainly their methodology) are in some extent an innovative issue, especially in Brazilian's fields.Therefore, the first motivation for this article is the novelty of this subject in the country, since Brazilian national industry is just beginning to deal with the end-of-leasing obligations, which will involve decommissioning operations. Besides, the absence of a complete official regulation developed by the Government, through its competent regulatory agency.The present paper comprehends a concise review of decommissioning offshore oil and gas production activities, including surface and sub-surface installations, predominantly based on European scenario due to its similarity with Brazilian's fields in some of its complex aspects. It also emphasizes which may be the methodology to achieve the 'Best Practicable Decommissioning Option' for present offshore production system, which comprise fixed and floating production systems. The current review shows the contemporary international scenario, which may be useful for both: industry and government regulatory agency. For the industry, it could give a significant upgrade to decommissioning operation programs. While for the government it could be useful in outlining specific regulations for decommissioning offshore installation. To sum up, the main ambition of this paper is stimulate debate about the pertinent issues as well illustrate some of the new ideas concerning decommissioning offshore production systems.12128Brent Spar Dossier: The Story, Photographic Record, Feature Stories, Press Releases and Technical Data, , www.shell.com/uk-en/directorv/0,4010,25268,00.html, [On-line], [01/2001]Meenan, P., (1998) Technical Aspects of Decommissioning Offshore Structures, , article from Decommissioning Offshore Structures, SPRINGER-VERLAG, London, Great Britain, IBSN 3-540-76213-2Scientific Group on Decommissioning Offshore Structures (1996) First Report, A Report by the Natural Environment Research Council for the U.K. Department of Trade and Industry (DTI)(2000) National Energy Balance, , Brasilia(2000) Annual Statistical Report of Brazilian Petroleum Industry(1999) Annual Report(1981) Law No 6,938, 6938. , August 31 st(1997) Law No 9,478, 9478. , August 6 th(1998) Decision 98/3 on the Disposal of Disused Offshore Installations, , www.ospar.org, Reference number: B-9.6, [On-line],[11/2000](2000) Guidance Notes for Industry: Decommissioning of Offshore Installations and Pipelines under the Petroleum Act 1998(1995) The AURIS ReportHughes, N., Fish, P., (2000) Decommissioning: Addressing the Issues - When?

  • Automated Methodology For Field Performance Optimization Developed With Horizontal Wells
    2015
    Co-Authors: Nakajima L., Schiozer D.j.
    Abstract:

    The main task of reservoir engineering is the development and management of a petroleum field in order to improve the profitability of a reservoir by raising production rates with minimum costs or increasing ultimate reserves. The performances of many horizontal well projects around the world demonstrate their effectiveness in achieving this objective, especially in offshore fields. However, this type of well has more complicated interaction with the reservoir, since its behavior is a function of a high number of parameters. The purpose of this paper is to present an automated methodology to optimize reservoir performance with horizontal wells, by using numerical reservoir simulation to provide the production forecast. The methodology is developed through the performance analysis for individual wells, group of wells and field. The objective of this analysis is to identify the parameters that define horizontal wells productivity, to realize a comparison between wells performances, and to investigate the causes of inadequate field and wells performance. The analysis is based on selected objective-functions: net present values, cumulative oil, gas and water productions and water injection. The methodology is developed to propose changes to optimize a strategy set previously. A concept of well neighborhood is used to allow simultaneous changes, which yield a lower number of simulation runs.265273Satter, A., Thakur, G., (1994) Integrated Petroleum Reservoir Management: A Team Approach, , PennWell Publishing Company, Tulsa, OKDixit, A.K., Pindyke, R.S., (1994) Investment Under Uncertainty, , Princeton University PressJosh, S.D., A Review of Horizontal Well and Drainhole Technology (1987) SPE Annual Technical Conference and Exhibition, , SPE 16868, Dallas, TX, U.S.A., Sept. 27-30Lacy, S., Ding, W., Joshi, S.D., Horizontal Well Applications and Parameters for Economic Success (1992) II Latin American Petroleum Engineering Conference, , SPE 23676, Caracas, Venezuela, Mar. 8-11Joshi, S.D., Ding, W., Horizontal Well Application: Reservoir Management (1996) 1996 International Conference on Horizontal Well Technology, , SPE 37036, Calgary, Canada, Nov. 18-20Aguilera, R., Artindale, J.S., Cordell, G.M., Ng, M.C., Nicholl, G.W., Runions, G.A., (1991) Horizontal Wells: Formation Evaluation, Drilling, and Production, , Gulf Publishing Company, Houston, TXAanonsen, S.I., Eide, A.L., Holden, L., Optimizing Reservoir Performance Under Uncertainty with Application to Well Location (1995) SPE Annual Technical Conference and Exhibition, , SPE 30710, Dallas, U.S.A., Oct. 22-25Wagenhofer, T., Hatzignatiou, D.G., Optimization of Horizontal Well Placement (1996) Western Regional Meeting, , SPE 35714, Anchorage, Alaska, U.S.A., May 22-24Bittencourt, A.C., Horne, R.N., Reservoir Development and Design Optimization (1997) SPE Annual Technical Conference and Exhibition, , SPE 38895, San Antonio, TX, U.S.A., Oct. 5-8Güyagüler, B., Horne, R.N., Uncertainty Assessment of Well Placement Optimization (2001) SPE Annual Technical Conference and Exhibition, , SPE 71625, New Orleans, Louisiana, U.S.A., 30 Sep. to 3 OctCruz, P.S., Home, R.N., Deutsch, C.V., The Quality Map: A Tool for Reservoir Uncertainty Quantification and Decision Making (1999) SPE Annual Technical Conference and Exhibition, , SPE 56578, Houston, TX, U.S.A., Oct. 3-6Pedroso Jr., C., Schiozer, D.J., (2000) Optimizing Locations of Wells in Field Development Using Reservoir Simulation and Paralell Computing, , Rio Oil & Gas, Rio de Janeiro, BrazilMezzomo, C.C., Schiozer, D.J., Methodology for Water Injection Strategies Planning Optimization Using Reservoir Simulation (2002) 2002 Petroleum Society's Canadian International Petroleum Conference, , Paper 2002-121, Calgary, Alberta, Canada, Jun. 11-13Moreno, R.B.Z.L., Schiozer, D.J., Use of Well Performance Parameters to Optimize Oil Field Recovery (2002) 2 nd Meeting on Reservoir Simulation, , Buenos Aires, Argentina, Nov. 5-

  • Methodology For Production Histry Matching Of Petroleum Fields Utilizing Logging Saturation Data
    'Society of Petroleum Engineers (SPE)', 2015
    Co-Authors: Grecco C.b., Schiozer D.j.
    Abstract:

    In the production history matching process, the reservoir simulation model is modified in a way that it becomes consistent with production data, keeping the observed restrictions of the geological characterization phase. This technique is complicated arid limited, mainly in mature fields, when the production history is not reliable, or in the beginning of production, when there are only a few observed data and uncertainty are higher. The research of new technologies has resulted in the development of new saturation data acquisition tools, such as 4D seismic and. TDT/TDM logging tools. The great challenge is how to use this data in a way to improve the petroleum production. History matching methodologies with saturation data from 4D seismic start to be found in literature but there are no projects that utilize saturation data obtained from well logging. The advantage of the logging tools is the data accuracy but, on the other hand, it is limited to a few feet around the wells. The main objective of this project is to integrate the traditional history matching process with logging saturation data obtained from the new logging tools, developing a new methodology to generate trustier simulation models and more reliable production forecasts. The saturation data is utilized as a new parameter to be matched as well as an auxiliary tool to help to determine critical regions which will be modified. An assisted history matching methodology utilizing saturation data, streamlines and an optimization algorithm is proposed. The proposed methodology was applied to a case with a well-know behavior. Parameters of the process are studied and detailed, finding the best way to use the data. The model was also history matched with no saturation information and predictions of the matched models are compared, showing the benefits and restrictions of the new methodology.

  • Influence Of Lumping And Equation Of State Tuning Methods On The Sub-salt Reservoirs Simulation
    Society of Petroleum Engineers, 2015
    Co-Authors: Mello S.f., Ligero E.l., Scanavini H.f.a., Schiozer D.j.
    Abstract:

    The Brazilian pre-salt oil reservoirs contain a considerable amount of methane, CO2 and volatile fractions under high pressure. Several authors suggest that the compositional reservoir simulation is fundamental for the description of their properties and prediction of oil production. Although this technique improves the quality of reservoir management, due to computational limitation, simplifications of fluid data are often recommended, affecting the quality of the compositional simulation. Petroleum reservoir behavior cannot be simulated in the most accurate way using present day computational resources. Simplifications such as lumping and tuning of equation of state (EOS) to describe mixtures have influence on the phase behavior. Fluid characterization becomes an important source of uncertainties in reservoir simulation because PVT data tuning is an inverse problem with multiple possible answers. The objective of this study was to show the impact of the description of the oil behavior under typical Brazilian sub-salt conditions considering oil production and computational effort. This was done through the study of EOS and comparison of the complete fluid with the lumped fluid descriptions. Since simplifications are adopted and PVT data-handling errors are introduced, it was necessary to detect and minimize them. The analysis of this study used comparisons of phase envelopes, MMP and reservoir simulations in a synthetic model. The studied model was based on the second model of SPE 10th comparative study, heterogeneous, using oil similar to that found in the Brazilian pre-salt, with 42° API, 3.55% molar CO2, and GOR 132.9 ft3 std/ft3. This work emphasizes the importance not only of experimental data quality but also shows the impact of the choice of regression and lumping methods. It also shows the importance of fluid modeling to obtain reliability in the reservoir simulation process.

    Abstract:

    Decommissioning offshore petroleum production activities have been progressively increasing the concern of the industry, government and distinct interest groups through the last years. There are at least two reasons for this sudden regard: first it is the maturing of several oil and gas fields around the world hi recent years; second, it is the growing impact of environmental concerns in international affairs.Although several works published address to some techniques and to potential problems/risks related to decommissioning of offshore oil and gas production installations, its operations (mainly their methodology) are in some extent an innovative issue, especially in Brazilian's fields.Therefore, the first motivation for this article is the novelty of this subject in the country, since Brazilian national industry is just beginning to deal with the end-of-leasing obligations, which will involve decommissioning operations. Besides, the absence of a complete official regulation developed by the Government, through its competent regulatory agency.The present paper comprehends a concise review of decommissioning offshore oil and gas production activities, including surface and sub-surface installations, predominantly based on European scenario due to its similarity with Brazilian's fields in some of its complex aspects. It also emphasizes which may be the methodology to achieve the 'Best Practicable Decommissioning Option' for present offshore production system, which comprise fixed and floating production systems. The current review shows the contemporary international scenario, which may be useful for both: industry and government regulatory agency. For the industry, it could give a significant upgrade to decommissioning operation programs. While for the government it could be useful in outlining specific regulations for decommissioning offshore installation. To sum up, the main ambition of this paper is stimulate debate about the pertinent issues as well illustrate some of the new ideas concerning decommissioning offshore production systems.12128Brent Spar Dossier: The Story, Photographic Record, Feature Stories, Press Releases and Technical Data, , www.shell.com/uk-en/directorv/0,4010,25268,00.html, [On-line], [01/2001]Meenan, P., (1998) Technical Aspects of Decommissioning Offshore Structures, , article from Decommissioning Offshore Structures, SPRINGER-VERLAG, London, Great Britain, IBSN 3-540-76213-2Scientific Group on Decommissioning Offshore Structures (1996) First Report, A Report by the Natural Environment Research Council for the U.K. Department of Trade and Industry (DTI)(2000) National Energy Balance, , Brasilia(2000) Annual Statistical Report of Brazilian Petroleum Industry(1999) Annual Report(1981) Law No 6,938, 6938. , August 31 st(1997) Law No 9,478, 9478. , August 6 th(1998) Decision 98/3 on the Disposal of Disused Offshore Installations, , www.ospar.org, Reference number: B-9.6, [On-line],[11/2000](2000) Guidance Notes for Industry: Decommissioning of Offshore Installations and Pipelines under the Petroleum Act 1998(1995) The AURIS ReportHughes, N., Fish, P., (2000) Decommissioning: Addressing the Issues - When?
