Oceanographic Data

ABSTRACT. This work presents a methodology for legacy seismic data from oil and gas industry use for water column acoustic imaging. The objective is to improve the detection of internal mesoscale ocean structures by combining the results of the seismic data processing with oceanographic parameters. The procedure to obtain these images is called seismic oceanography and is an emerging tool for large-scale analysis of physical properties and processes of the ocean. The seismic data collection from the oil industry can be used to extract seismic oceanographic information since they both have similar survey configuration requirements for their data acquisition. The seismic data used were obtained from the Brazilian Oil Exploration Database and the oceanographic data were obtained in World Ocean Database. The methodology used to detect oceanographic structures was divided into four stages: data selection; oceanographic parameters analysis; seismic oceanography processing and interpretation; and combined analysis of seismic data with oceanographic data. The analysis and interpretation of the data showed that reflectivity curves calculated using oceanographic parameters have strong correlation with the seismic oceanography data. The detected reflections corroborate with the literature information about the boundaries of the water masses of the region and with abrupt gradients of the oceanographic parameters.Keywords: seismic oceanography, acoustic image, water masses, water column reflections, oceanographic parameters. RESUMO. Este trabalho apresenta uma metodologia para utilização de dados sísmicos do acervo da indústria de petróleo e gás para gerar imagens acústicas da coluna d’água. O objetivo é melhorar a detecção de estruturas oceânicas em mesoescala por meio da combinação de resultados de processamento de dados sísmicos com parâmetros oceanográficos. Denominada de oceanografia sísmica, o presente método é uma ferramenta emergente para a análise de propriedades físicas e processos dos oceanos. O acervo de dados sísmicos da indústria do petróleo pode ser utilizado para extrair informação sísmica oceanográfica, uma vez que ambos têm configurações semelhantes para a sua aquisição de dados. Os dados sísmicos utilizados foram obtidos da Base de Dados de Exploração e Produção e os dados oceanográficos foram obtidos no World Ocean Database. A metodologia utilizada foi dividida em quatro etapas: seleção de dados; análise de parâmetros oceanográficos; processamento e interpretação da oceanografia sísmica; e análise combinada de dados sísmicos com dados oceanográficos. Resultados mostram que as curvas de refletividade calculadas utilizando parâmetros oceanográficos têm forte correlação com os dados da oceanografia sísmica. As reflexões detectadas corroboraram comas informações da literatura sobre os limites das massas d’água da região e com gradientes abruptos dos parâmetros oceanográficos.Palavras-chave: oceanografia sísmica, imagem acústica, massas d’água, reflexões na coluna d’água, parâmetros oceanográficos.

Fundamental Limitation

Despite the ever-increasing use of 3D seismic data in today’s exploration and production activities, 2D seismic data continue to play an important role in the oil and gas industry. Interpretations of 2D regional and megaregional surveys are essential elements of integrated exploration programs, establishing frameworks for basin analysis, structural synthesis, and play fairway identification and mapping. When correlating and mapping horizons on 2D migrated seismic data, interpreters use certain practical techniques for handling structural misties, which are caused by the fundamental limitation of 2D migration to account for out-of-plane components of dip.

Human Interpretation

Given the recent increase of seismic data quality owing to improvements in seismic acquisition and processing, it is surprising to realise that the oil and gas industry is still using standard desktop screens with 256 colour resolution software displays, and for most of the seismic representations, using only three types of colour bars (peak-trough, grey scale or rainbow) for human interpretation, comprehension and decision making processes. Knowing that these displays show 0.000006% of the details captured in 32 bit resolution data, it is a wonder: is the oil and gas industry using the available data to its maximum potential to decrease the risk of drilling dry wells? Astronomy and medical imaging tackled these issues long ago and inspired by them, the oil and gas industry is able to use a 24 bit colour space for representing seismic data in a more appealing way. These innovative seismic data representations are called colour blends and are created using sources such as frequency decomposition products, angle stacks, edge attributes, 4D vintages or any other seismic attributes colour-coded with primary colours. Colour blends have not yet become mainstream due to availability of the tools. The cognitive cybernetics approach allows a more balanced input between data driven processes, interpreter skills and guidance, and has recently been made available for use with colour blends—a breakthrough in interpretation. This extended abstract shows recent advances in these two techniques and how they benefit to the geological and geophysical work based on a case study from the Australian and New Zealand sector.

New Millennium

As we enter the new millennium, seismic data acquisition is in an interesting position. Because of overcapacity of seismic acquisition crews related to the downturn in the oil and gas industry, acquisition technology is essentially “frozen” in place. Companies previously active in seismic data acquisition research have limited these activities, or eliminated them. Some advances related to improving the resolution of seismic data through improved acquisition methods are being made, but much more effort is being directed towards improving the efficiency of acquisition.

Abstract In an Oil and Gas field development plan, identifying appropriate reservoir location of a field and deciding the best design strategy as well as meeting the economic hydrocarbon viability are imperative for sustainability. 3-Dimensional seismic data have become a key tool used by geophysicists in the Oil and Gas industry to identify and understand subsurface reservoir deposits. In addition to providing excellent structural images, the dense sampling of a 3D survey can sometimes make it possible to map reservoir quality and the distribution of Oil and Gas. Primarily, Seismic data sets were retrieved from the ongoing Kolmani exploratory work of upper Benue trough, bordering Gombe-Bauchi communities of Nigeria and Simulation study from improve design was conducted using PETREL and SURFER software's to obtain numerous coordinates from the source and receiver lines respectively and subsequent formation of strategic-designs that shows different arrangements of the prospect area, an interpretation of the acquired data sets that indicates the reservoir location appropriately and probable onset of drilling spot. The well to seismic was also merged using synthetic seismogram that shows the location of reservoir (s) from the seismic data obtained and four different wells with anticipated depths respectively. The overall aim of the whole design and simulation studies is to aid petroleum Geologist and Geophysicists avoids common pit falls by reducing dry holes and increasing the overall number of productive wells prior to actual commencement of drilling in this prospect area and elsewhere.

Federal tax revenues from the main sectors of the Russian economy after the 1998 crisis are examined in the article. Authors present the structure of revenues from these sectors by main taxes for 1999-2003 and prospects for 2004. Emphasis is given to an increasing dependence of budget on revenues from oil and gas industries. The share of proceeds from these sectors has reached 1/3 of total federal revenues. To explain this fact world oil prices dynamics and changes in tax legislation in Russia are considered. Empirical results show strong dependence of budget revenues on oil prices. The analysis of changes in tax legislation in oil and gas industry shows that the government has managed to redistribute resource rent in favor of the state.
