The world's demand for energy is accelerating, while its hydrocarbon reserves are diminishing. Producers compelled to explore and produce oil gas in more challenging environments maximize recovery existing reservoirs. New technology has always been a key success. One such new seismic acquisition using ocean bottom station (OBS) nodes (Berg et al., 1994; Ronen 2003; Amal 2005; Docherty Granger 2005).
Qingzhuan dark tea polysaccharides (QDTP) have been complexed with Zinc (Zn) to form the polysaccharides-Zinc (QDTP-Zn) complex. The present study investigated protective effects of QDTP-Zn on ulcerative colitis (UC) in mice. UC mouse model was induced using dextran sodium sulfate (DSS), followed by oral administration (0.2 and 0.4 g kg
Summary In offshore peninsular Malaysia there are strings of major hydrocarbon bearing fields which affected by shallow gas clouds. This poses a problem in imaging using the P-wave data from conventional streamer or OBC 2C surveys suffer frequency dependent attenuation, multipathing, scattering, internal multiples, velocity inversions and mode conversions due to charged sediments. 2D–4C is proven be useful areas where 2D-PS-wave provides clearer image as compared 2D-P-wave imaging.

霍布斯鲍姆作为英国马克思主义历史学派的代表人物之一，在马克思主义唯物史观的指导下，对帝国主义进行了深入的研究，并且在他的著作中提出了独到的见解。在进行相关理论研究时，霍布斯鲍姆认为帝国主义概念有“广义的帝国主义”和“狭义的帝国主义”之分，以此揭示了帝国主义的复杂性。另外，霍布斯鲍姆还认为在帝国主义阶段民主政治的日益衰败、工人阶级意识的不断成熟、民族主义的逐渐转型，这些都为更加全面地理解帝国主义的历史提供了参考。总体来看，霍布斯鲍姆从历史发展的视角出发，对帝国主义的概念以及帝国主义阶段民主政治的发展进行了深刻思考，其研究为考察当代帝国主义问题提供了一定价值的历史依据与理论支撑。
A three component VSP experiment was carried out in the metasedimentary Whitewater group of Sudbury Structure. Processing data focused on velocity analysis, wavefield separation, shear‐wave waveform modelling, hodogram and integration surface‐seismic borehole geophysical data. Wavefield separation processing synthetic modelling resulted a realistic model corridor‐stacked compressional section correlates well with surface seismic reflection The shear wave provides an additional constraint...
Conventional method processes multi-component data from a flat datum. In time processing the statics corrections to datum by P and S wave replacement velocities may produce different datums for PP PS sections due unknown or inaccurate
Summary Shallow S-wave velocity model building is very important for land and Ocean Bottom Seismic PS data processing. Surface waves, propagating along the near surface, provide useful information shallow estimation. In this study, multi-modal surface wave inversion (MM-SWI) was used to build a high resolution recently acquired Node survey. Super gathers were constructed improve signal-to-noise ratio spatial of dispersion spectra. Auto-picking curves then implemented. To overcome strong...
Ocean Bottom Stations provide wide-azimuth multi-component data with great advantages for exploration, reservoir characterization, and identification of drilling hazards. However, due to the high cost deploying OBS nodes, large receiver intervals are used. In practice, poor illumination sparse receivers is a major problem. This problem particularly, but not exclusively, associated gaps in coverage shallow targets, greatly exasperated if some nodes fail. The same affects both ocean bottom...
The Sudbury Structure has been used as a test site for various geological remote sensing verification studies. authors have received and processed number of new data sets interpretation. include two ERS-1 SAR, CCRS's airborne C-SAR, geophysical ground survey data. Recently there were also LITHORPOBE related experiments including the regional high resolution reflection seismic surveys (1991) refraction (1992). space-borne SAR look direction bias correction integrated with other detailed...
For exploration in the Chepaizi area, Junggar Basin of Northwest China, lateral lithologic variations due to deltaic and fluvial sediments present major challenges characterization oil sand reservoirs. The reservoirs exist so-called “sweet spots”. However, conventional P wave is not able effectively distinguish true “bright spots” from false ones, which leads high drilling risk. example, a strong reflection amplitude observed target layer for Che89, highly productive well drilled 2006. But...

P023 A DISCUSSION ON THE SHEAR- TO COMPRESSIONAL-MODE (SP): THEORETICAL PRACTICAL AND ECONOMIC Abstract 1 While it is very common to acquire process and interpret compressional-mode (P) data that have been converted the shear-mode (S) reciprocal scenario S P (SP) uncommon. We discuss some of practical economic theoretical issues associated with SP mode. Since P-wave seismic standard within our industry will likely only be available when nine component are being acquired. The two main...
E011 A VELOCITY ANALYSIS PROCEDURE FOR MULTICOMPONENT DATA WITH TOPOGRAPHIC VARIATIONS Summary 1 We have modified the normal-moveout (NMO) equation for both P-wave and converted-wave (Cwave) data to handle surface elevation changes we implemented this in our velocity analysis NMO correction programs. For C-wave case also developed a new method that combines common conversion point (CCP) binning with set of trial γ (Vp/Vs) values thereby reducing errors introduced by approximate asymptotic...
