The present paper is focused on the application of some of the multifrequency (9.5 and 94 GHz) continuous wave and pulsed EPR techniques to study the dynamics and structure of asphaltenes and vanadyl complexes from the crude oils and bitumen at near room temperature. The features of the observation of EPR in these systems at high frequencies are pointed out. Longitudinal and transverse relaxation times of asphaltenes and vanadyl complexes are measured. Usage of the data obtained for DNP of protons of crude oils and bitumen is discussed.

This paper describes the features of translational characteristics of oil molecules by using nuclear magnetic resonance method with pulsed magnetic field gradient (gradient NMR). It is shown that the rheological properties of heavy oil samples (viscosity) do not completely correlate with the measurement of self-diffusion coefficient. It is caused by distribution of oil samples according to their molecular composition and molecular weight as well as their complex supramolecular organization. It is noted that the best agreement with the viscosity characteristics is achieved via the introduction of a new average coefficient, which is a weighted sum of the inverse of the partial self-diffusion coefficients.

New Geotechnology for the Old Oil Provinces | Year: 2013

Searching for the new hydrocarbon prospects becomes more and more actual in the recent years due to the annual oil production exceeding the quantity of the explored reserves. Therefore the necessity for the new oil deposits discovery and the development of explored oil fields increased annually. An important role in new oilfield discoveries and in supplementary exploration of the known is given to seismic 2D and 3D survey that are the most accurate and accordingly highly demanded in the geological sphere. The efficiency of the applied seismics is convincingly shown in the example of a number of oil deposits discoveries of Novo-Yelkhovsky field controlled by the local structures.

In recent years exploration of new hydrocarbon prospects became more and more pressing problem for the reason that annual production exceeds the quantity of the explored reserves. Therefore the need for discovery of new hydrocarbon deposits grows every year. At present all the large positive structures are discovered and explored by drilling in the territory of the Western Siberia. So certain oil prospecting interest is presented by the depression zones, where maximum of alluvial sediments have been accumulated. Seismic 2D CDP prospecting operations carried out in the area with the extremely low exploration by drilling in the range of Mogutlorskiy trough allowed not only mapping of the perspective prospects, but also at qualitative level to detect the estimated lensing sandy bodies, being characterized with the improved reservoir properties.

This paper presents a method for an open-hole well completion analysis using a Borehole Acoustic Scanner and a Borehole Video Imager. Acoustic ultrasonic scanning has been used for lithological well profile analysis, cavernous and fractured-cavernous zones identification in a testing well. The video imager provides important information about the well geological structure and fractured zones. It is shown that the combined interpretation of the borehole acoustic scanner data and video imager data provides complete geological information about the testing well. Corresponding approach could be useful for developing acoustic scanning template database.

The processing of research results of sector equipment of acoustic logging in the carbonate section was carried out taking into account the separate registration of wave patterns into four independent spatial sectors. It was detected the significant difference in the arrival times of acoustic waves to the different sectors of equipment. Authors propose a formation procedure of monopoly or dipole wave packets considering the separate registration on different sectors and shifts between wave patterns of individual sectors. The difference in the values of interval times obtained for the wave packets recorded by the classical method and calculated with allowance for shifts between sectors can result to differences in the calculation of porosity coefficient to 4 or more absolute percent. Apart from the formation of the correct wave packet processing of wave patterns on different sectors allows to reveal the occurrence of elastic anisotropy for well diameter. In addition, analysis of interval time curves allows to reveal areas with occurrence of inclined layers in relation to the well. Further processing of such data will allow to receive a geological information like we getting from processing of borehole imagers.

Methods for estimating the slowness of elastic waves according to a multi-element acoustic logging are discusses in the paper. Compare slowness curves of longitudinal and transverse waves for carbonate deposits is held. Interval times curves estimated by Semblance and dispersion methods have better convergence with each other. The reason for this is that these methods estimate the group velocity, as opposed to the hodograph method, which gives an estimate of the phase velocity. Convergence of slowness curves for the transverse wave is generally belter than convergence of curves for the longitudinal wave. All methods yield similar values slowness estimation errors. © Copyright 2016.
