Heavy Oil Reservoirs with Sandstone Rock Type, Properties and Recovery Methods
Authors M. Seidy Esfahlan, E. Khodapanah and S.A. Tabatabaei NejadSummaryHeavy crude oil is defined as any liquid petroleum with API gravity less than 22.3 °API according to World Petroleum Congress definition. Heavy oil reservoirs are distributed all over the world. This paper explains the recovery methods of heavy oil reservoirs in sandstone rock types, and also the challenges faced in oil production of them. It’s concluded that detailed reservoir characterization study is necessary to reach the high oil production in each heavy oil reservoir. Cold heavy oil production with sand is the most common method in heavy oil reservoirs with sandstone rock type and has usually more benefits than sand controlled production in high permeability reservoirs. Steam based methods are usually economic because of their high recovery increment. One of the most common problems in high permeable sandstone reservoirs is sand production and so severe water channeling. In these cases polymer injection, ASP injection and installing AICDs can be useful. If the high water cut is originated from bottom-hole aquifer, drilling horizontal wells is also a useful method for suppressing water coning.

Full-Waveform Modeling for Solving the Direct and Inverse Seismic Problems in the Tomsk Region
Authors I. Romanchenko, K. Starkov, A. Ivlev, M. Tarakanovsky, D. Litvichenko, Y. Pavlovsky and V. LisitsaSummaryUp till recently, the Pre-Jurassic formations were not considered as a separate exploration target because of their complicated structure which required adaptation of conventional exploration methods to be looked at. Because of its complex structure and the existence of the more readily available reserves of the Jurassic and Cretaceous reservoirs, the Paleozoic formations have not been studied well enough, and some fundamental research will help reveal new regularities. As a part of Paleozoic project, the full-wave modeling was used in order to reduce risks during field seismic surveys for the pre-Jurassic complex in the Tomsk Region. Results of testing seismic data processing and interpretation procedures on model data was used to formulate requirements for the methodology of seismic field acquisition in the area of study and an optimal graph for processing 2D and 3D seismic data .

An Econometric Model for Effectiveness Assessment of Enterprises Interactions in the Oil&Gas Sector to Form Resource and Economic Assets
Authors D. Dushenin and D. MilyaevSummaryWith the depletion of traditional sources of hydrocarbon raw materials, the attention of representatives of the oil and gas sector is increasingly attracted by non-commercial resources at the moment, the cost-effective development of which should be coupled with the advent of new, cheaper and higher-quality technologies. The interaction of enterprises to improve the methods of search, exploration and production is quite difficult to model. First of all, this is due to the geological, technological and stochastic uncertainties that accompany this process. The report proposes the architecture of a mathematical model, which, according to the authors, most correctly summarizes the aspects of innovative development in the oil and gas industry and should contribute to the formation of approaches to the controlled impact on innovation in order to cost-effectively develop problematic hydrocarbon resources. The proposed methodology combines agent models, Bayesian networks, numerical simulation methods and allows you to take into account the probabilistic aspects of the process of developing new technologies.

Ion Modified Water Flooding in Low-Permeable Carbonates of Bashkirsky Formation in Russia-Tatarstan
Authors M. Rezaei Koochi, M. Varfolomeev and A. ShakirovSummaryIn this work we studied the effect of ion modified water on recovery factor and injectivity of the Bashkisky formation. For preparation of ion modified water added 5g magnesium sulfate to 100g fresh water. In order to define the effectiveness of ion modified water injection, the oil saturated cores were flooded by fresh water and when water-cut reached 100%, we replaced it with ion modified water. According to the results, recovery factor for fresh water was about 9.5% and pressure drop during injection was 232 kPa. By replacing fresh water with ion modified water recovery factor increased up to 14.5% and pressure drop decreased down to 136 kPa. Flooding simulation showed that by adding magnesium ions to fresh water, scale tendency of CaCO3 salt decreased from 22 to 1.2.

On the Current State of the Problems of Assessing the Permeability of Highly Clayey Sandstones and Shales
By B. EnikeevSummaryCurrently, to evaluate the permeability of strongly clayey rocks and shales, the most active methods are FZI, Digital core and modeling within the framework of a capillary lattice scheme. The report compares the achievements and prospects of these approaches and proposes to use four types of equations for mixtures of ellipsoids to calculate the properties of capillary lattices. In this case, the coordination number of capillaries begins to play the role of the depolarizing factor. The possibilities and limitations of this approach based on the processing of empirical data are considered.

Simulation of Reflected and Diffracted Waves in Seismograms Before and After Migration
Authors A. Shevchenko, I. Fedyaev, A. Korolev and E. FomichevaSummaryTo search for faults and fracture zones from seismic data, various approaches are used to separate the scattered component of the wave field. Scattered or diffracted waves formed on faults or in fracture zones can be distinguished by the wave fields before or after migrated gathers. Migration procedures, as a rule, are focused on building images on reflected waves and the display of diffracted waves on the results of migration can be distorted. It is well known that on CDP stacks, diffracted waves are partially suppressed due to the difference between their kinematics and reflected waves. The aim of this work is to model hodographs and gathers of reflection and diffraction in seismograms before and after migration in order to study the possibility of releasing the energy of the scattered wave field component.

Authors I. Shelokhov, I. Buddo, A. Pyankov and A. SmirnovSummaryThe geological section of Eastern Siberia is an extremely complex object for a seismic exploration. The reason for this is the extremely high variability of the upper part of the section lithology, rough terrain, and permafrost rocks. This paper delivers an alternative approach to predicting the velocity model of the upper part of the section. The approach is based on the original method of restoring the elastic-velocity characteristics from the data of transient electromagnetic method (TEM) in the near zone.

Assessment of the Geological and Geophysical Parameters of Tectonic Faults to Refine the Geological Model of Kovykta Gas Condensate Field
Authors A. Otsimik, A. Ilyin, I. Shelokhov and A. SmirnovSummaryThe Kovykta gas condensate field has a complex geological and tectonic structure. Gas-saturated reservoirs bed in the subsalt sediments. However, the prospects for gas of the overlying halogen-carbonate interval approved by well drilling: flow rates reach 200 thousand m3 / day. To predict both the prospects for gas and drilling settings the structure and tectonics have to be examined. The aim of research is to estimate the depth of the faults identified in the suprasalt and halogen-carbonate intervals, and their possible relation to the productive subsalt interval. The analysis includes fault systems location from various vintage data, including the results of the relief lineament analysis and the results of seismic, magnetic and gravity surveys, as well as electromagnetic studies with TEM technique. A comprehensive analysis of geological and geophysical data made it possible to trace the fault zones of the northeastern direction associated with the Orlengsky arch and the Burungino-Bereinsky depression, from the surface to subsalt sediments. The deep-depth origin of the fault zones and the intense fracture were found, which shows the possibility of fluid migration from the productive reservoirs of the subsalt interval to the overlying rocks of the halogen-carbonate interval.

Authors V. Korobkin, E. Novikov, M. Nakatsukasa and M. PetrovaSummarySakhalin offshore is a region with extensive exploration and production activities. There are difficult geological settings with complex overburdens, fault systems and near-surface gas that affect seismic image quality. In article authors demonstrate how can be improve the image on one of the field from Sakhalin offshore. New OBN data acquired in 2018 were used as input for processing. The key points of project were improvement of reservoir image below gas cloud and clarification of structural plan and faults. QFWI and QPSDM techniques were used to solve these problems. As result, we built detailed anisotropic Q-model that used for Kirchhoff TTI pre-stack migration with compensation of Q-effect. It allowed us to restore the image below gas cloud that should help in further interpretation, geological forecast and well planning. We also describe parameters of new OBN survey, input data characteristics, demonstrate velocity model building flow and comparison with vintage cube. Finally, some additional instruments for further improvements are discussed.

Anisotropy in Seismic Data. Prerequisites and Real Possibilities of Seismic Exploration for Fracture Development Zones Determining and its Relationship with Well Productivity
Authors P. Didenko and K. SiraevSummaryAnisotropy is the directional dependency of a material’s physical properties. The higher anisotropy values are the higher is fracture density or the difference between horizontal stresses. The study of seismic anisotropy and the various effects associated with it is the subject of close attention of most experts, whose area of interest includes fractured and unconventional reservoirs. Anisotropy parameters provide additional information, which can be used for fracture and faults identification. In this work, the requirements for input seismic data, various methods for studying the anisotropy of seismic data (Curvature Analysis, Azimuthal NMO, Azimuthal AVO and Anisotropic Inversion), and the possibilities of fractured zones determining were considered. Actually, the type of seismic survey controls number of available methods for anisotropy analysis. When we can use only one seismic volume –a final stack, it will be possible to estimate anisotropy only through indirect methods. For WAZ surveys, where azimuthal information was saved during processing, it is possible to work with azimuthal gathers or azimuthal angle/offset stacks. In this case, all tools are available to study anisotropy.

Methodology for Express Definition of Water Inflow Source in Water-Flooded Wells Operating Multi-Layer Deposits by High-Precision Studies of Water Composition
Authors M. Shipaeva, D. Nurgaliev, I. Siraeva, I. Bagmanov and V. SudakovSummaryAn important problem in field development is the high water cut of the production. This problem is very important in fields at a late stage of development, when the number of water-flooded wells increases while oil production decreases. Determination of the source of water incoming to production wells and possible problems in the well bore due to annular circulation or breakthroughs of water from aquifers or from injection well, is one of the most important tasks in the development of multilayer deposits. Today, many methods are used to detect these problems, but all of them require shutting down the well and launching special equipment, which is sometimes a time-consuming process in view of the construction features of the wells and is characterized by a significant delay in detection time. The approach proposed in the work is based on the analysis of the results of a study of the geochemical composition of produced water, which is unique for horizons of different age. The relevance of the work is caused by the lack of available operational methods for obtaining information about the water inflow sources, which prevents the effective development of multilayer deposits.

Alignment and Comparison of Top Drive and Near-Bit Accelerometers for Seismic-While-Drilling
Authors A. Egorov, P. Golikov, I. Silvestrov and A. BakulinSummaryA traditional seismic-while-drilling processing workflow requires a pilot measurement of the drill bit vibration signature. The sensors for the recording of these vibrations are commonly located at the top drive or near the drill bit. In theory, the downhole sensor provides a better measurement of the drill bit signal. While currently available near-bit instrumentation allows high-frequency seismic recording, it suffers from a non-synchronized internal clock with significant drift. Time alignment and drift need to be accounted for, as seismic-while-drilling processing requires the timing accuracy on the order of a millisecond. We propose a two-step correction procedure. First, the linear part of the clock drift is corrected using global optimization, which is followed by a time-variant correction based on cross-correlation. This methodology allows us to align the top drive and near-bit sensors with a timing accuracy acceptable for seismic-while-drilling applications.

Research on Sealing of Cap Rock of D Block in Xushen Gas Field
More LessSummaryThe sealing of cap rock is a key indicator to the evaluation of sealing of a gas storage and an important reference for designing parameters of a gas storage. The qualitive evaluation for the sealing of the cap rock is carried out by the evaluation of lithology, thickness, physical properties, micro structure of pore throat. On that basis, a calculation model of breakthrough pressure for cap rock is built with the experiment of breakthrough pressure and log analysis, which realizes the quantitative evaluation for sealing of cap rock. And a sealing classification standard of sealing for cap rock is built. The results show that the sealing of the D Block in Xushen Gas Field is good and the sealing level can be classified into strong to relatively strong level, which shows good potential for building a gas storage.

Investigation of the Influence of the Formation Destruction Process on the Reservoir Properties of the Reservoir During Hydrocarbon Production
By S. EfimovSummaryThe purpose of this work is to study the process of destruction of a productive reservoir and removal of sand to determine the permissible depression on the formation during the operation of wells in gas fields. On the basis of laboratory core studies modeled the process of reducing pore pressure and fracture of the core, the influence of processes of destruction on the change of reservoir properties of productive formation. The research is based on geomechanical analysis of changes in filtration and capacitance properties. The analysis is reduced to comparing the mechanical properties and strength of rocks with the stresses that occur during the development of hydrocarbon deposits. When the value of the stress acting on the productive layer is lower than the strength, elastic deformations of the rock dominate, and the layer is deformed slightly. If changes in the stress acting on the rock during development (reduction of reservoir pressure) exceed some acceptable values, then irreversible plastic deformations begin in the rock.

Rock Typing of Upper Cretaceous Rocks Using Core Analysis Data and Resistivity Logs
Authors N. Kostin and K. DvirnyakSummaryRock typing is one of the most important tasks to be solved during the preparation of petrophysical model. Increasing number of new carbonate reservoirs, as complex and unique sedimentary deposits, requires a concentration of efforts aimed at increasing the efficiency of linking core analysis results and interpretation of well logging. The aim of this work is to combine rock typing methods into integrated system and to obtain input data on its basis for petrophysical modelling. This work involved well logging and core analysis results for 513 core samples. Initial types were selected in accordance with the sedimentary environment and the energy level of hydrodynamic processes. Determined rock type boundaries were linked to the results of mercury injection data (A.J. Katz and A.H. Thompson, 1986; Kamath J., 1992; Abedini A., 2011). Typing process also involved estimation of flow zone indicator (McPhee C. et al, 2015: Tiab D., Donaldson E.C., 2015) and classical approaches for carbonate reservoir characterization (Lucia, F.J., 2007). The results of typing were combined with the resistivity logs.

Thermochemical Treatment as a Multifunctional Method of Enhanced Oil Recovery
Authors M. Rezaei Koochi, M. Varfolomeev, H.E. Belaid and S. TalipovSummaryIt’s clearly obvious that a technology alone cannot act as a panacea, but thermochemical treatment method can act as a multifunctional technique. This method is based on the decomposition reaction of ammonium nitrate. This work is planned to find study the thermobaric effect of thermochemical fluid, determine its effect on petrophysical parameters of formation and rheological aspects of oil. To measure the released pressure and temperature, 5 ml of the thermochemical fluid was injected into the reaction cell and these parameters were registered in real time regime. It was found that pressure and temperature in reaction zone increase up to 80 atm and 230 ? respectively. Experiments on core plugs show that after thermochemical fluid a network of fractures occurs. Rheological tests show that because of reaction products oil viscosity reduces from from 630 to 55 m.Pa.s.

Determining the Angular Parameters of Reflecting Borders in 3D Seismic Exploration
Authors V. Bondarev, S. Krylatkov, N. Krylatkova and A. KrylevskayaSummaryA method for determining the angular parameters( angles of incidence and azimuths of incidence) of seismic boundaries using standard 3D seismic survey materials is described. This makes it possible to more effectively analyze the history of sedimentation in the studied geological strata. The solution of this problem is carried out for the General calculation points (CMP) selected on the research area. It is assumed that the nature of changes in the depth of the values of the effective propagation velocity of elastic waves is known from the observation profile. Under these conditions, based on the use of a set of source routes of seismograms of common excitation points, you can select special collections of seismic routes that are United by a common reflection point for them at seismic boundaries.

Controlled Directional Transform of Seismic Attributes for Geological Features Detalization
By E. RozhenkovSummaryVarious geobodies have specific shape on vertical and horizontal projections resulting in geometrically anisotropic features in seismic data. Such features can be enhanced by performing controlled directional transform of seismic attributes based on local linear Radon transform. The approach is to represent results of such transform as polar diagrams, which are then used for anisotropy magnitude estimation as well as number of its prevailing directions and their azimuths. These data are helpful in emphasizing anisotropic features and can even help to distinguish some of them (faults and river channels). Other possible applications of this method include azimuthal filtering and automatic tracking. The proposed approach aids geological interpretation in a variety of ways while being flexible to perform on different structural and dynamic attributes.

Analysis of the Confirmability of Seismogeological Models Within the Perm Territory Based on the Results of Newly Drilled Wells
Authors A. Gorbunov and A. BrazhnikovSummaryБольшая часть территория Пермского края на данный момент является хорошо изученной. В связи с этим, вероятность открытия крупных залежей стремительно сокращается, снижая потенциал прироста сырьевой базы региона. Для решения данной проблемы применяется пространственная сейсморазведка 3D, позволяющая детальнее изучить особенности строения недр и выявить потенциально перспективные объекты для поисков новых залежей нефти и газа. Сейсмические исследования, проводимые по методике МОГТ 3D, являются важным инструментом при поисковых работах, позволяющим как значительно уточнить информацию о выявленных перспективных объектах, так и выявить новые. Однако, несмотря на эффективность данной методики имеют место неточности построений, выявленные последующим бурением новых скважин. В связи с этим, вопрос повышения точности сейсмических прогнозов является актуальным. Сведение к минимуму подобных неточностей позволит снизить риски при размещении скважин и, тем самым, повысит подтвержаемость выявленных структур.

Application of Inverse Deconvolution Algorithm. Eastern Siberia Case Study
Authors S. Suslov, N. Zhuravko, E. Uzbekov, R. Filatov, D. Fedorova, A. Mukhatzhanov, A. Zherlygin, A. Sorokin and V. FagerevaSummaryNowadays the algorithm of “robust” surface-consistent deconvolution is widely used. Many seismic data processing companies practice the implementation of fairly aggressive noise attenuation workflows while evaluating trace spectra for subsequent decomposition. However, aggressive noise reduction is often performed in a quick mode without extensive testing and for these reasons is worse than the final version of production noise attenuation workflow. One possible way to solve this problem is to derive and re-calculate deconvolution operators after noise attenuation procedures. The convolution is a linear transformation, which allows us to declare its complete reversibility, and, consequently, the reversibility of the entire procedure of surface-consistent deconvolution. Due to data analysis of a clean dataset without noise interference allowed us to noticeably improve the amplitude-frequency characteristics especially in the low-frequency zone. Another advantage of this approach is the ability to significantly improve the performance of processing large volumes that involve new data acquisition during project fulfillment. In this paper, we consider examples using the reversibility of the deconvolution procedure in a data processing graph.
