Opis:
Understanding the mechanism by which oil is displaced from the porous medium requires knowledge about the role of wetting and capillary forces during EOR. Knowledge of the effect of wettability on oil production is also a key point for understanding the behavior of multiphase flows in the reservoir. A literature review indicates that wettability is one of the ma in factors controlling and regulating the distribution of oil and water in the reservoir rock. Therefore, the resolution of problems associated with the calculation of oil resources, operation and analysis of core deposits, must take into account the wettability of rock. Therefore, the study of such phenomena as wettability is still valid today. In the paper reservoir rock wettability and its types were desc ribed. Direct and indirect methods of determining the wettability were characterized, the graph of capillary pressure is used to characterize the wettability. In order to determine the effect of wettability on multiphase flow in porous media are discussed petrophysical parameters: capillary pressure, relative permeability and hydrocarbon saturation of the rock. Characterized wettability of each of Characterized wettability of each of carbonate and sandstone reservoirs.

Opis:
Enhanced oil recovery methods can significantly increase recovery from offshore oil reservoirs provided that the appropriate method is selected. Enhanced oil recovery methods aim to recover the remaining original oil in place by applying additional energy sources and minimalize flow resistance in the field. The application of these technologies results in enhancement, or replacement of natural or physical processes of displacement and modifies the composition and physical properties of formation fluids. The use of EOR technologies in offshore environment is limited compared to onshore fields. Constraints imposed by the offshore environment are associated with technical difficulties as well as economic risk. Before choosing the most appropriate EOR method for particular environmental conditions the restrictions associated with: large well spacing, disposal geological description as well as availability and cost of EOR agents, weight and space constrains or high capital cost requirements should be considered. Reservoir lithology is limiting the applicability of specific EOR methods. This paper presents a comprehensive review of EOR projects which are appropriate or possible for sandstone reservoirs containing light-oil in offshore field. The possibilities and limitations of selected methods are introduced.

Opis:
At present, oil can be ranked among the most important fuels and energy minerals. In the majority of cases, primary recovery moves, however, merely in the range of 30-40% of original oil in place (geological reserves). But with deposits containing very viscous oil, percent recovery is much lower, i.e. from 5 to 10%, and the use of primary methods brings about only little economic effect. It is the application of so-called secondary and tertiary methods that enables the effective exploitation of reserves. In the submitted study, we present some results obtained by laboratory experiments with using polymers and surface-active agents in the displacement of highly viscous oil from reservoir rocks
Obecnie ropa naftowa należy do najważniejszych paliw i źródeł energii. Jednakże w większości przypadków ze złóż pozyskiwanych jest około 30-40% ropy. W przypadku złóż ropy charakteryzującej się dużą lepkością procent ten jest dużo mniejszy, tj. od 5 do 10%, a zastosowanie metod pierwotnych przynosi niewielkie zyski ekonomiczne. Dopiero zastosowanie tzw. metod wtórnych lub trzeciorzędnych gwarantuje efektywne wykorzystanie złóż. W artykule przedstawiono wyniki badań laboratoryjnych nad wykorzystaniem polimerów i surfaktantów do zwiększenia produkcji ropy o dużej lepkości

Opis:
Enhanced Oil Recovery methods (EOR) are known since long time, but in recent years they have been used primarily in the U.S. mostly for research purposes. The increased interest in their use was in the 70's of the twentieth century, and associated with the increase in oil prices. Currently for several years there has been a return to the these methods, including offshore fields. Experience in the application of EOR methods in Poland is small, currently no exploitation is carried out using them. The purpose of this article is to present the current trends and latest technologies in enhanced oil recovery methods in terms of the applicability by the Polish oil companies. Statistical data of current and planned EOR methods in the world with special emphasis on offshore reservoirs is presented. Current trends in technological development of EOR methods are given, both which are still in the phase of laboratory tests and the first tests on fields such as: carbon dioxide flooding, water alternating gas injection, Iow salinity water injection, carbonated water injection, conventional technologies of polymer gels and thermally activated polymers.

Purpose: The purpose of this article is to highlight the main problems that arise during the final stage of oil field development. Based on the identified problems using the EORgui program, Petroleum Solutions Ltd it is necessary to select the most effective method to increase oil recovery and study the most optimal tertiary oil recovery method using a hypothetical field model as an example, which will ensure the maximum oil recovery factor. Design/methodology/approach: Study of oil tertiary displacement efficiency by applying tertiary methods were performed using EORgui software from Petroleum Solutions Ltd and Petrel from Shlumberger. Findings: The results of the research show that the most optimal method of oil recovery increasing for this hypothetical field is the injection of carbon dioxide. When using this method, the oil recovery rate reaches 23%. Research limitations/implications: When using carbon dioxide, it is necessary to have sources of supply near the field, as well as increased corrosion of petroleum equipment is possible to occur. Practical implications: The use of the proposed approach is an important condition for the effective extraction of residual oil reserves for most fields developed using the reservoir pressure maintenance system. Originality/value: The article presents the characteristic features of residual oil location, reveals the conditions for effective usage of methods to increase oil recovery and their selection procedure.

Opis:
Eni oilfield has been experiencing production decline with increase in water output. The implementation of enhanced oil recovery (EOR) can help to extract some percentages of the original oil in place (OOIP). EOR methods are capital intensive and few are environmental hazardous. In a bid to address this issues, this paper discusses on an alternate economically viable enhanced oil recovery technique which has the potential to curb the challenges of other conventional EOR methods. This work suggested a 3 stage approach of applying microbial enhanced oil recovery (MEOR) method for oil recovery in Eni field. The reservoir characteristics in Eni field were studied, the average porosity value of the reservoirs is between 0.238 and 0.241, while water saturation ranges between 0.127 and 0.13. Other production data include; Initial reservoir pressure which ranges from 2328 to 2553 Psia and has a reservoir temperature ranging from 170°F to 180°F. The Average API gravity ranges from 20.5 to 34.2, while the initial GOR ranges from 350 to 396. Oil viscosity was between 0.57cp to 2.57cp while gas viscosity was between 0.65cp to 0.67cp. The reservoir characteristics and parameters were found suitable for the application of MEOR technique for effective oil drainage from the delineated reservoir compartments. Microbial flooding was found to be matured in reservoirs with temperature less than 200°F, brine salinity not more than 100,000 ppm, water depth not more than 3500m and permeability should be above 30 (Md). It is recommended that MEOR approach should be applied in Eni Oilfield for increment of oil production and reduction in water cut due to its efficiency and economic viability.

Opis:
The most important area of a producing reservoir is the near wellbore which is within 5fts into the formation. All fluids have to flow through it, usually at high flow rates. Problems associated with formation damage near wellbore occur frequently, resulting in permeability impairments and increased pressure losses. During drilling, emulsion formation affects reservoir deliverability and ultimate recovery. Most of the existing methods to aid mitigation near oil well damages involve the use of empirical models. Conducting experiments, frequent shut down of wells for proper well test analysis and pressure maintenance are highly expensive and time consuming. Therefore, this paper aimed at optimizing reservoir pressure using cross section comparisons of mathematical tools and experimental for improved emulsion transport near wellbore. Formation damage mechanisms are highlighted for the purpose of reservoir engineers. The engineers must be vigilant about the potential formation damages near wellbore and then can mitigate the impact of damages by understanding its mechanisms how various types of damages might impact production, Assessment, control and remediation. The transient hydraulic diffusivity partial differential equations (THDPDE) models developed. The model equations were resolved using finite difference method and implemented by writing codes in MATLAB language. The solutions obtained were validated using field data and experimental work. The results indicated pressure depletion over time without injection but increases under the influence of increased injection rates enhancing the oil recovery. Experiments were also carried out to evaluate the effectiveness of the emulsions as displacing fluid for enhanced oil reservoir. In this paper, a new modeling scheme is proposed and is based entirely on cross section comparisons involving modification of Darcy’s equation with experimental work in an attempt to optimize reservoir pressure and improved oil-in-water emulsions near wellbore. The knowledge that oil-in-water emulsion type exists and that a new scheme to uniquely characterize the near wellbore damage is developed. The present authors suggest cross section comparisons of both modeling and experimental section for predictions of the data in the study area. Numerical simulation has proved to be effective in simulating emulsions near wellbore. The formulated models indicate pressure depletion over time, but increased thereafter, resulting to increased oil recovery and significant improvement in emulsions transport near wellbore.

Opis:
Exploitation of oil from the reservoir initially is performed by primary methods that use natural energy reserves, that allows for partial exploitation of geological resources (30%). Further oil resources depletion requires the implementation of appropriate methods to support exploitation, secondary methods, consist mainly in the physical oil displacement and third methods, in which additional types of energy aid the process of exploitation. The use of this methods may contribute up to a twofold increase in the degree of the geological resources depletion. One way to increase the exploitation is the injection of CO2 into the oil fields (CO2-EOR). This gas interacts physically and chemically on the reservoir rocks and oil contained in them, improving the conditions of its production. The technology of CO2 injection into the reservoir allows not only to increase oil production, but also gives the possibility of storing this gas in reservoirs, which is beneficial from the viewpoint of its impact on the environment. In the article was made a comparison of the oil recovery effectiveness between waterflooding and CO2-EOR method for Jastrząbka Stara reservoir. For this purpose, were made simulations of waterflooding and injecting CO2 for selected oil reservoir on the basis of the CO2PROPHET program. We analyzed different variants of injection of water and gas, both the amount of injected media, and the method of injection (only water, only gas, change injection of gas and water). Based on the results of modeling was estimated the amount of oil possible to extract by both methods and the recovery factor of the geological resources of the selected oil reservoir.

Real produced water containing a combination of organic compounds was treated with zinc oxide nanoparticles. In this study, ultraviolet radiations were used to find the efficiency of removing the oil content from the water produced that brought from the Al-Ahdab oilfield in kut/ Iraq by advanced oxidation process (AOP) using (ZnO/UV) in batch system and continuous system. In batch system were studied the effect of zinc oxide concentration (nanoparticles), time of irradiation, and pH. The highest removal rate of oil from the produced water (100%) was obtained during the following optimal conditions: ZnO NPs as catalyst = 55 mg/L, pH =3, at the time of irradiation of 90 minutes in batch experiments. In the continuous system, the effects of flowrate, number of UV-A lamp and time of reaction were studied, the results obtained were the efficiency of decomposition decreases with increasing the flow rate of solution in reactor, the maximum removal efficiency of the process (ZnO/UV) was 80% at 20 mL/min and irradiation time 120 min. In general, zinc oxide is beneficial through its high oil adsorption capacity in addition, It lowers the amount of oil in the produced water.

W artykule przeanalizowano możliwości pozyskania CO2 z dużych punktowych źródeł emisji w Polsce dla celów intensyfikacji wydobycia ropy naftowej EOR (Enhanced Oil Recovery) poprzez podziemne zatłaczania tego gazu. Technologia ta stosowana jest od kilkudziesięciu lat, głównie w USA, gdzie wykorzystywany jest antropogeniczny i naturalny CO2. W Polsce, ze względu na niewielkie zasoby, jak i niewielkie wydobycie naturalnego dwutlenku węgla, do zabiegów intensyfikacji wydobycia ropy naftowej może być wykorzystany antropogeniczny dwutlenek węgla. Przedstawiono największych emitentów tego gazu (powyżej 500 Gg/rok), scharakteryzowano podstawowe procesy technologiczne, w których on powstaje, lokalizację zakładów przemysłowych, koncentrację dwutlenku węgla w gazach spalinowych/przemysłowych. Podkreślono aspekt ekonomiczny i środowiskowy wykorzystania CO2 do intensyfikacji wydobycia. Lokalizację największych emitentów dwutlenku węgla określono w stosunku do położenia złóż węglowodorów różnej wielkości i o różnym stopniu sczerpania.

This technology has been used for decades, especially in the USA, where natural and anthropogenic gas is used. In Poland due to little reserves and natural gas production, anthropogenic CO2 for EOR process could be used. The biggest CO2 emitters are presented (above 500 Gg/year), basic technological process which produce the gas, industrial plants locations, concentration of carbon dioxide in flue/industrial gases are characterized. Economical and environmental aspects of using CO2 for EOR are underlined. Location of the biggest CO2 emitters was defined in connection with hydrocarbon reservoirs location which have various sizes and stags of exploitation.

Opis:
Crude oil, a major source of energy, is being exploited as a driver of the economy throughout the world. Being a limited resource, the price of crude oil increases constantly and the exploitation of mature reservoirs becomes essential in order to meet the ever-increasing energy demands. As conventional recovery methods are not sufficient to fulfil the growing needs, there is an incessant demand for developing new technologies which can help in efficient tertiary recovery in old reservoirs. Petroleum biotechnology has been emerging as a branch that can provide solutions to major problems in the oil industry, including increasing oil production from marginal oil wells. The enhanced oil recovery (EOR) method comprises four methods – chemical, thermal, miscible, and immiscible gas flooding – as well as microbial interference to increase recovery of the remaining hydrocarbons trapped in reservoir rocks. Biochemically enhanced oil recovery comprises an array of blooming technologies for tertiary oil recovery methods which is eco-friendly, cost-effective, and efficient in extracting the residual oil trapped in reservoir rocks. Biochemical enhanced oil recovery (BcEOR) is based on the principle of using biochemical by-products produced by microbial species to enhance oil recovery, etc. All these technologies work on the principles of reducing viscosity, increasing permeability, modifying solid surfaces, emulsifying through adherence to hydrocarbons, and lowering interfacial tension. BcEOR technologies either employ the beneficial microorganism itself or the biochemical by-products produced by the microbial species to enhance tertiary oil recovery. This review paper discusses the chronological development of biologically enhanced oil recovery and its various mechanisms.
Ropa naftowa jest wykorzystywana na całym świecie jako główne źródło energii. Ze względu na ograniczone zasoby ropy naftowej jej cena stale rośnie, a eksploatacja ze złóż dojrzałych staje się niezbędna do zaspokojenia ciągle zwiększającego się zapotrzebowania na energię. Ponieważ konwencjonalne metody wydobycia nie wystarczają do zaspokojenia coraz większych potrzeb, istnieje nieustanne zapotrzebowanie na rozwój nowych technologii, które mogą pomóc w efektywnym wspomaganiu wydobycia ze starych złóż metodami trzecimi. Ostatnio biotechnologia naftowa staje się gałęzią, która dostarcza rozwiązań dotyczących głównych problemów przemysłu naftowego, w tym zwiększenia wydobycia ropy z brzeżnych odwiertów ropnych. Wspomaganie wydobycia ropy naftowej (EOR) obejmuje cztery rodzaje metod: chemiczne, termiczne, tzw. mieszające i niemieszające wypieranie ropy gazem, a także oddziaływanie mikrobiologiczne w celu zwiększenia wydobycia węglowodorów uwięzionych w skałach złożowych. Biochemiczne metody wspomagania wydobycia ropy naftowej to szereg rozwijających się technologii dla trzecich metod wspomagania wydobycia, które są przyjazne dla środowiska, racjonalne pod względem kosztów i efektywne, jeżeli chodzi o wydobycie ropy rezydualnej uwięzionej w skałach złożowych. Biochemiczne wspomaganie wydobycia ropy naftowej (BcEOR) oparte jest na zasadzie, zgodnie z którą biochemiczne produkty uboczne wytwarzane przez gatunki drobnoustrojów są wykorzystywane do wspomagania wydobycia ropy naftowej itp. Wszystkie te technologie działają na takich zasadach jak: zmniejszenie lepkości, zwiększenie przepuszczalności, modyfikacja powierzchni ciał stałych, emulgowanie poprzez adhezję do węglowodorów, obniżenie napięcia międzyfazowego. Technologie BcEOR albo wykorzystują pożyteczny mikroorganizm jako taki, albo wykorzystują biochemiczne produkty uboczne wytwarzane przez gatunki drobnoustrojów w trzecich metodach wspomagania wydobycia ropy naftowej. W niniejszym artykule przeglądowym omówiono chronologiczny rozwój biologicznych metod wspomagania wydobycia ropy naftowej i ich różne mechanizmy.

Opis:
The purpose of the article is to enhance the oil recovery coefficient of lower Menilite deposits of the Strutynsky oil field by using an ASP solution (a mixture of three agents: alkaline, surfactant and polymer (ASP)). The tasks were solved by choosing an effective method of enhancing oil recovery by using EORgui software and hydrodynamic modelling software by using Petrel, Eclipse software. Calculations of computer simulations indicate the possibility and technological efficiency of residual oil extraction through the use of ASP solution. After using the method of oil recovery enhancing in the lower Menilite deposits of the Strutynsky oil field by means of ASP solution, the coefficient of final oil recovery will increase from the initial value of 10.4% to the predicted 17.6%. For the first time, geological and hydrodynamic models have been created for the conditions of the Lower Menilite deposits of the Strutynsky oil field, and the most appropriate method for oil recovery enhancing by using the EORgui program has been selected. The suggested method for oil recovery enhancing can be applied within the framework of the concept for reviving the Lower Menilithic deposits of the Strutynsky oil field, as well as in other oil fields of Ukraine, which are developed with waterflood patterns and have similar geological and physical characteristics.
