Oil and Gas Potential of Frolovskaya Suite for Krasnoleninsk Arch
More LessSummaryA brief description of the geological structure of Frolovskaya suite and its analogues is given, as well as its position in the cross-section, lithological description, wave-based division, and depositional environments. Well materials and 3D seismic data interpretation were used to study the entire cross-section of Frolovskaya suite to identify the areas of potential net reservoirs. The learning is based on the upper part of the suite, AK1–3 reservoirs, with proved net reservoirs presence and their oil and gas potential. As a result of the work performed, it was identified that Frolovskaya suite can potentially contain other promising oil targets. Such targets may occur above horizon B in the zone of 60 - 40 ms (about 100 - 60 m) and under reservoirs AK1–3, 45 - 65m below the bottom. There is also a possibility of presence of lenticular oil bodies in the clinoform part of the suite

High Resistive Anomalies Beneath Permafrost Layer as New Hydrocarbon Prospecting Indicator
Authors D. Yakovlev, A.P. Afanasenkov and R.P. VolkovSummaryDetailed geophysical survey was carried out in 2014–2015 in Novotaymyr block located in Yenisey-Khayanga trough. One of main percularituy of the survey area is presence of sevral proven hydrocarbon deposits: Ozernote gas deposit, Payakhskoe oil deposit and baikalovskoe gas codensate deposit.
A specific patter was detected according to the electrical prospecting data interpretation: high resistive anomalies are presented above the hydrocarbon reservours at depth of about 300–800 m below permafrost layer.
Despite the lack of definitive conclusions about the nature of the revealed high resistive anomalies identified anomalies in the upper part of the section, the mere presence of these anomalies can be treated as hydrocarbon prospecting indicator that can be used in solving the following tasks:
- Prediction of oil and gas occurrence. Near-surface high resistive anomalies in the upper part of the section are directly linked with the industrial accumulation of hydrocarbons in the deep productive layers.
- Defining the boundaries of the deposits. In areas characterized by subhorizontal bedding and absence of non-permeable layers and/or subvertical permeable faults, the migration of hydrocarbons occurs mainly in the vertical direction. Therefore, based on the concept of nature, related to gas hydrates and free gas, it is possible to make an assumption about the similarity of dimensions and outlines of near-surface anomalies with hydrocarbon reservoirs at depth.
- Identification of zones of geological and drilling hazards. It is obvious that the accumulation of gas or/and gas hydrates beneath permafrost layer could cause destruction of engineering infrastructure structures and drilling sites on the surface.

3D Scale-based Geostatistical Simulation of Porosity Heterogeneity in Sandstone Formation
Authors W.J.M. Al-Mudhafar and M. BondarenkoSummaryРазличные источники петрофизических свойств пласта приводят к разным моделям неоднородности пласта. Данных о пористости по результатам геофизических исследований больше, чем данных по результатам исследований керна. Распространенным способом пространственного моделирования является алгоритм кригинг, как наилучшая линейная несмещенная оценка пространственной неоднородности. В данной статье используется метод последовательного Гауссовского моделирования (SGSIM) для создания реализаций пространственного распределения пористости с учетом типа фаций по результатам геофизических исследований и исследований керна. Метод SGSIM основан на анализе вариограмм, что позволяет понять геометрию и непрерывность распределения коллекторских свойств. Модель распределения пористости по результатам геофизичексих исследований лучше, чем по результатам анализа керна.

3D Pixel-Based Stochastic Lithofacies Modeling in a Tidal Sandstone Reservoir
Authors W.J.M. Al-Mudhafar and M. BondarenkoSummaryThe geological facies modeling is a crucial problem in the overall reservoir characterization as it affects the reservoir heterogeneities and fluid flow performance prediction. The main purpose of the research is to adopt the stochastic lithofacies modeling in a tidal sandstone reservoir (Main Pay) of South Rumaila Oil Field to build the geological structure of the reservoir. Based on the core measurements, the reservoir has three main lithofacies: Sand, Shaly Sand, and Shale as the literature indicates that it encompasses mainly of sandstone with some interbedded shale zones. In addition, the main pay formation was deposited in a tidal sand-rich environment that the sand channels are stacked and prevailed everywhere across the formation.
The Sequential Indicator Simulation (SISIM) has been used to build the categorical image, pixel by pixel considering the nonparametric condition distribution. SISIM depends on the variogram to address and model the variation between any two spatial points from the available data. Therefore, 12 different variograms have been built given the three lithofacies in four different directions: 0°, 45°, 90°, and 135° The resulted lithofacies models given the three lithotypes have indicated good matching with the original formation depositional environment of tidal dominated and sand-rich environment

Application of Frequency-Dependent Analysis for Prediction of the Relative Changes in the Rermeability of the Reservoir
Authors A.I. Rozhkova, G.M. Goloshubin and A.E. KorolevSummaryTraditional approach to predict reservoir properties involves map construction of the expected net thicknesses and porosity on the base of dynamic attribute analysis of the wave field and inversion results. The reservoir permeability is an important parameter for field development, its forecast on the base of seismic data is not widely spread, although there are publications that illustrate the possibility of such forecast. The article presents the results of applying the frequency-dependent seismic attribute MOBATR, which characterizes the relative changes in the permeability of the reservoir. This attribute aimed at detecting frequency anomalies in the spectrum of the wave group, reflected from porous fractured reservoir. In accordance with the analytical solution, on which based the calculation of the attribute, its values change indicates on the proportional change in permeability along the reflector

Effective Use of Seismic Interpretation for the Tasks of Geological Modeling
Authors Y.A. Dyakonova, D.S. Machukaev and Y.V. BiryukovaSummaryConsistency of seismic, geological and well data is an important task in the reservoir modeling. Conducting seismic interpretation in view of error determination and application of obtained results in creation of ensemble of realizations of the structural model allows for a probabilistic assessment of initial OIP and risk determination in well placement decisions, research conduction, etc. This paper discusses the impact of uncertainties of seismic data on initial OIP for fields with complex tectonic structure when turning from drilled to undeveloped parts of the field. It is shown that structural factor determined by seismic data greatly influences the spread of initial OIP probability estimates P90-P50-P10. A methodology is described for uncertainty estimation on the stage of seismic interpretation and results utilization for reservoir model construction.

Authors I.V. Kuvshinov, L.A. Stasyeva and V.V. KozlovSummaryThis work presents results of laboratory studies and field tests of viscosified oil-displacing composition NINKA-Z with controlled viscosity and alkalinity, developed at Institute of Petroleum Chemistry SB RAS. This composition is both oil-displacing and flow-diverting, and can be used for enhancing oil recovery by increasing reservoir sweep and oil displacement efficiency. Not only injectors can be treated by NINKA-Z, but also producers, with reagent-cyclic technology, similar to cyclic steam stimulation, without heating. Field tests were held in 2014 on steam flood area of Permo-Carbon deposit of Usinskoye oilfield. Five steam injection wells were treated, and results were observed on 75 producing wells. The effect was more than 10 thou.tonne of extra oil, proving the effectiveness of the technology.

Enhanced Oil Recovery on the Basis of Invert-Emulsion Solution with Simultaneous Use of Acid Composition
By V.V. SergeevSummaryScope:
Oil fields in the late stage of development are basically characterized by high rate water flooding of the formed products. The reason is the breakthrough of water from the reservoir pressure maintenance system by highly permeable interlayers of the layer. Our experiments showed that the usage of certain amount of invert emulsion solution (IES) decreases the water cut significantly and increases the oil recovery almost twice.
Processes:
Considerable advantage of IES in comparison with solutions which are carrying out the same functions is its ability to disolve at interaction with a hydrocarbonic phase, therefore, application of IES as the blocking solution will allow to decrease a colmatation of oil zones and selectively will isolate only water-bearing interlayer.
Special type of acid dissolves the carbonate component of the reservoir, increases the permeability of oil saturated interlayers and expand the drainage process significantly that results twice higher volume of oil extraction from the same bed.
Results
- Special IES solves the problem that exists in case of water flooding using polymers;
- Special acid composition contains a number of surfactants, water repellents and corrosion inhibitors.
- the effectiveness of technology of intensification of oil is confirmed within the field trial on Pashninsky oilfield in 2014

New Perspectives of High Productive Wells Drilling in Low Permeable Reservoirs in West Siberia
Authors O. Boldina, E. Tsyganova, E. Samakova and Y. IonnikoffSummaryОсновным объектом разработки на территории Поттымско-Ингинского месторождения Красноленинского свода являются континентальные отложения верхней части тюменской свиты. Относящиеся к категории трудноизвлекаемых запасов пласты тюменской свиты имеют сложное геологическое строение: они характеризуются резкой литологической изменчивостью, как по разрезу, так и по латерали, коллектора имеют низкие фильтрационно-емкостные свойства. В данном докладе будет рассмотрен пример того, как тщательное планирование скважины: ее местоположения, конструкции, способа заканчивания – позволило пробурить высокодебитную скважину в неоднородных низкопроницаемых тюменских пластах.
Результаты атрибутного анализа сейсмического 3D куба, а также интерпретация сейсмических 2D профилей в зоне отсутствия 3D сейсмики, были использованы для выделения области развития меандрирующего речного пояса, относящегося к пластам ЮК2–3. Анализ результатов геофизических исследований скважин показал, что в пределах обнаруженной аллювиальной системы доля коллекторов составляет около 60%, мощность отдельных песчаных тел составляет метры, ширина - сотни метров. Для увеличения степени вскрытия коллектора было решено бурить в пределах найденного речного пояса скважину горизонтального типа с последующим проведением многостадийного ГРП. Конструкция скважины и параметры ГРП были оптимизированы с целью достижения максимального дебита и минимизации технологических рисков.
В итоге, пробуренная горизонтальная скважина запущена в фонтанном режиме с дебитом нефти, двадцатикратно превышающим дебиты соседних вертикальных скважин с большеобъемным ГРП. Полученные результаты показывают высокий потенциал разработки трудноизвлекаемых запасов при правильном геолого-инженерном подходе.

Intensification of Oil Production Under Vibration Impact on the Producing Formation
Authors E.A. Marfin, Y.I. Kravtsov, A.A. Abdrashitov and I.S. MetelevSummaryImproving the efficiency of oil field development is possible due to the intensification of oil production by a vibrating impact on producing formation. Numerous laboratory and field research confirm this. Intensification of oil production is due to the many phenomena occurring in the productive strata at imposing elastic vibrations. Selecting the desired frequency of formation stimulation in this case is one of the important issues. The essence of the proposed idea is that the frequency of vibrating influence should be chosen close to the natural frequencies of noise filtration of producing formation. This paper investigates the spectra of noise filtration of samples of artificial and natural porous media. We present some results of the impact of elastic vibrations on the producing formation. It is shown that a greater effect in the oil production achieved at frequencies close to the frequency of noise filtration.

Authors E.G. Zhemchuzhnikov and D.A. PopovSummaryThe permissible minimum accuracy of OBN’s positions calculation is estimated by help of direct water wave’s first breaks (FB) from ordinary shots – based upon record parameters (sample rate – first of all) of reflection method.
The article contains the methods&soft of receiver positioning and list of record’s parameters, which are especially sensitive to receiver-coordinates errors by reflection method’s processing.
The position’s calculation criterion is formulated; relying on this the minimum necessary accuracy of OBN’s positions was estimated (Barents and Kara Seas shelf’s areas, typical records) – up to 8m.
The article contains the calculation’s method, man-hour and result’s accuracy.
The corrections necessity of “mirror” solutions by 2D seismic survey is considered expressly.
The basic conclusion: the seismic survey (reflection method) is all-sufficient instrument both for data acquisition and for bottom receiver’s positioning. Under this circumstance the purchase and use of hydro acoustic systems providing the seismic survey is not necessary.

Application of Robust Surface-Consistent Deconvolution
Authors N.S. Zhuravko, Y.V. Laptev, O.O. Adamovich and A.O. TinakinSummaryThe analysis of seismic data requires in many cases (AVO studies for example) the preservation of true amplitudes. This precludes the use of any processing step that modifies seismic amplitudes in an irreproducible way. Amongst such processes the trace by trace deconvolution is notable and this is one reason why the surface consistent deconvolution has become the preferred method. Other reasons for its popularity are the more stable and thus superior operators that are derived from spectra that have passed the strong but realistic filter of the surface consistent decomposition. In practice non surface consistent noise like ground roll or sporadic noise bursts that is prevalent in most land data can impair the surface consistent deconvolution to the point of uselessness. Because of these problems the surface consistent deconvolution could be used with land data only in connection with elaborate trace editing or in a processing sequence that is not altogether true amplitude. The modified surface consistent deconvolution (Robust Deconvolution) apply a method of deconvolution that attacks mentioned problems: Robust Solver that gives unbiased results even in the presence of strong inconsistent noise and Robust Application that enables the computation of additional temporally limited operators that abate the noise.

Marine Data Processing Results Reliability Increasing
By B.S. EsinovSummaryIn conventional marine seismic surveys, the air-guns and streamer(s) are placed at certain predefined depths below the sea surface. The decision of source/receiver depths for any given survey is based on several conditions, including weather conditions, desired frequencies, equipment type etc. In addition to those, the location of the notch in the frequency spectrum created by the surface ghost reflections is something that must be considered. Ghosting is a direct result of placing the source and receivers near a sharp discontinuity, which is the water/air contact in marine acquisition. The result of deghosting procedure are images quality environment, increases the reliability of geological tasks. There is no need to focus on the positive effects of this procedure during the expansion of the spectrum to higher frequencies. In recent times, a growing interest is the low frequencies that increase the stability of seismic inversion and tying processing results to well data.

3D Seismic Data Processing Technology for Near Surface Effects Compensation Using Surface Waves Frequency Dispersion Curves
Authors O.O. Adamovich and Y.V. LaptevSummarySeismic data processing nowadays meets new requirements during conventional 3D surveys. The key idea to meet these requirements is to use new seismic data processing approaches. One of the approaches is to use surface wave as a useful signal which is treated as noise in conventional seismic data processing. Surface waves travel along free surface and carry information about near surface properties which are expressed mainly in frequency dispersion. Surface waves area dispersion study may allow us to build detailed near surface velocity model. Joint surface and refraction waves velocity model may be built and further used for statics calculation and prestack depth migration. Another possible application of built velocity model may be direct linear waves modeling and consequent subtraction. This approach may help to preserve reflected waves signal especially at low frequencies and near offsets which can improve further low frequency inversion response and AVO-behavior

Method for Resolving the Ifluence of Near Surface Heterogeneities During Velocity Depth Model Building
Authors E.L. Svistova, B.S. Esinov, I.Y. Radionov and A.E. KorolevSummaryTrue depth imaging is one of the main problems of seismic processing and, first of all, depends on the high-quality depth velocity model. There are many different methods of depth velocity model building. The model itself, and, therefore, the result of migration highly depends on the methods of resolving the influence of complex near surface overburden. The underestimation of the subsurface influence leads to a distortion of seismic data over the whole section. However, the application of large statics shifts to the data, which solve the static problems in time, leads to distortion of seismic velocities and, consequently, to difficulties in the depth velocity model building. In this paper, we suggest a method for resolving the complex near surface overburden at the stage of building the depth velocity model using seismic refraction waves.

Advantages of the PSR-method for Eastern Siberia Seismic Data Processing (Yakutia)
Authors V.V. Kondrashkov and A.Y. GlagolevSummaryIt is kwown there are many difficulties and unsolved problems in the East Siberia data processing. In this paper it is recommended to use the PSR (Parametric Sweeping of Reflections) method to obtain a positive results of data processing in such conditions.
Rugged area, high-velocity section, absence of low-velocity layer, presence of traps are factors that don’t allow to calculate usual statics because the result depends on angle of emergence. Authors suggest to use post-critical reflections and refracted waves as a solution to these problems.

Authors E.V. Borisova, K.O. Vyatkina, V.N. Gileva, R.S. Shulga and I.S. ShakhmatovSummaryIn this work we marked one of the approaches to the determination of reservoir properties with control of saturation by method of NMR on the example of one well:
On the basis of the material composition has been determined four major lithological types of rocks of Bazhenov Formation: 1. Pyritized argillite 2. Phosphate rock 3. Limestone fine-crystalline 4. Clay-siliceous rocks. For holding reseach we selected two cores from the same place. One of them was used for determining the residual water by method of Dean-Stark, the second was researched by methods of NMR and gas saturation.
As a result, we have the following conclusions:
- From the viewpoint of elaboration lithological types of 2 and 4 are more interesting because they can store and transport fluid.
- Lithological type 4 is the most interesting for us because it is capable to store fluid, but its capacity of transporting is unknown according the results of method of NMR volume of mobility of fluid is small

Authors L.V. Lyukshina, G.Y. Shilov, R.N. Mustaev and K.Y. OdintsovaSummaryOil tight oil (Hadumskaya Suite Ciscaucasia) is a serious object of future production using new technologies. Hadumskaya Suite dedicated to the Maikop series sediments (early-middle Oligocene), represented by dark-grey and brown clays with interbeds of marls. In many cases, hydrocarbon deposits are associated with fractured schistose strata.
Hadumskaya Suite on lithological grounds divided into 3 horizons: the lower – przejscie, medium – olbinski (ostectomy layer), the upper horizon of Maraskino beams. Geochemical studies of sediments of the Oligocene showed that they were deposited in a reducing atmosphere. Organic matter presents fine sapropel formations of nature and, to a lesser extent, inclusions humus-lignite material. The content Sorgue decreases with increasing carbonate rocks. On the assessment of the petroleum generation potential of large capacity to generate hydrocarbons from sapropelic-humic and humic-sapropelic type of organic matter Oligocene rocks. It is characteristic geilweilerhof (pore) pressure. Our research on the evaluation of pore pressure gradients in HS, it was found that in those intervals where gadomski retinue gradients of pore pressure was normal, there was formed deposits of oil. Here clay rocks Hadumskaya Suite sealed, as it does not contain abnormally high pore pressures. As a consequence, in the interval of occurrence Hadumskaya clay rocks could crack, leading to the formation of cholesterol fractured reservoirs and subsequent to the formation of deposits
