Geomodel 2015 - 17th Scientific-Practical Conference on Oil and Gas Geological Exploration and Development | Year: 2015

Currently the northeastern territories, which host significant potential hydrocarbon resources, take on particular importance among the regions of Russia promising for oil and gas. The western part of the Yenisei-Khatanga regional trough and the zone of its junction with the West-Siberian Plate are among the promising regions with proven commercial oil and gas occurrence. The paper considers the main Callovian-Turonian reservoirs in the western Yenisei-Khatanga regional trough, provides sandstone thickness maps and qualitative assessment of petroleum potential.

Geomodel 2012 - 14th Scientific-Practical Conference on the Problems of Integrated Interpretation of Geological and Geophysical Data During Geological Modeling of Hydrocarbons' Deposits | Year: 2012

On the basis of complex interpretation of the time seismic cuts given GIS on 42 wells and petrophysic to materials, the digital geological model of distribution of sandy collectors of jursko-cretaceous adjournment is constructed. Perspective zones for formation of deposits of hydrocarbons are allocated, laws of distribution of breeds-collectors are shown.

Seismic researches are carried out for the purpose of exposure of geological breaking zones in the extraction pillars of coal mines (realized by "NTC Vostochnii" limited company (Kemerovo) and FSUE "SNIIGGiMS" (Novosibirsk) in Kuznetsk Basin, 2010 2011). Solving this problem could result in lowering the considerable expenses which mines suffer when a breaking zone is found that wasn't expected or has uncertain configuration. With seismic data obtained with POCA-A autonomous station (patents RU 2366981, 90223, 103937), the registered wave identification is carried out, the systems of wave hodograph curves are constructed, the seismic tomography processing of waves passing through the medium is carried out, and features of coal-bed structure and borders of its erosion are specified.

The results of near-surface seismic experiments with the high-frequency source on piezoelectric elements are presented in this paper. It has demonstrated that the first brakes of refracted waves can be correlated in offsets about 300 meters. The results show high resolution of the obtained data and that the method is better in wave generation that the traditional methods of wave generation.

Induction and polarization fields are additive in the near-zone of the transmitter and its dependence from dimension and/or configuration of transmitter-receiver system is different. This allow to separate induction and polarization fields using the results of transient soundings with different transmitter-receiver system. The examples of induction and polarization fields separation in polymetallic ores exploration are introduced.

The performed transformation of the CDP section along the 2-DV, 2-DV-A, 3-DV profiles to dynamic and geometrical attributes of the acoustic section allows a system of comprehensive images characterizing specific features of the earth's crust geology. This information synthesis in the form of a deep geodynamic model has given new detailed ideas of the geology of the Chukchi terrane, Okhotsk-Chukchi volcanogenic belt and the area of its junction with the Koryak terrane. The widespread development of elements of indentation structure of the Earth's crust in the area of the 2-DV profile bears witness to the dominant tectonic mode of compression in the area of investigation. Structures of tension stress are subordinate and mainly developed in conditions of shift-tension stress (pull-aparts). It was stated, that dating back to Mezosoic the boundary between the Siberian and Amur plates runs inside the Stanovoy megablock, and its structure is represented as a combination of wedge scales and blocks brought out from different depth in the area of interaction of continental lithosphere plates.

The Earth's crust macromodel is constructed from MG-CDP data using the ReapakRK+ system, which is based on seismic inversion, clusterization of obtained pulse characteristics, and calculated Reapak-attributes. The analysis of these data has allowed formalizing some identification characteristics of the justified transition from seismic fields to structural and qualitative description of individual elements of the Earth's crust macromodel. Fields of seismic inversion attributes in the Earth's crust sections in the oil-and-gas pools of Siberia and North-Eastern Russia have been analyzed. Indications of anomalous zones which may be conductors for mantle solutions in its upper parts have been established. These indications may be used for forecasting giant hydrocarbon accumulations.

A criterion of oil and gas occurrence has been suggested, which can be used to predict petroleum pools in sedimentary deposits. The paper provides substantiation of this criterion in terms of geochemistry, brief information on procedure of gas-geochemical survey and processing of chromatographic analysis results. The results of field trials are also discussed in the paper.

Seismic stratigraphy, as method of geological interpretation seismic sections is wide practical useful in order of Oil & Gas exploration. Negative side of this method is strong dependence between wave image of geological object and frequency features of seismic data. Those features are related with type and area condition of source, processing and etc. Another problem is consist in interference of refracted signals on the seismic traces. This problem can solved by the additional processing (inversion) of stacked section. One of the ways is creating the impulse section from the ordinary section by Dynamic Compression (DC). DC can divide interference wave packets for the detail analyzes local structures. DC is improving time definition of the seismic record and quality of litho-stratigraphic interpretation. The paper describes the algorithms and presents experimental results of DC on different models.

The lower limits of reservoir properties of the Osinsky, Yuryakh, and Preobrazhensky carbonaceous rocks have been defined in parametric borehole Chaikinskaya-367. The reservoir/non-reservoir boundary by exploration target selection must be drawn based on three parameters: residual water saturation factor, porosity, and permeability. It is shown that successful testing of fractured-porous and fractured reservoirs requires tangential stress evaluation in the well bore zone. Lacking inflow from reservoirs in the parametric borehole Chaikinskaya-367 is due to the testing with a pressure drawdown exceeding the critical value.
