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.

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.

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.

Abstract The purpose of this paper is to present a general overview of the Buzios field development plan, projects’ features, and main achievements so far. The development plan adopted a strategy to pursue the balance between acceleration and cash flow optimization, to maximize the return on the huge investment on the block acquisition, and the risk management related to developing several Greenfield Projects simultaneously. To reduce reservoir uncertainties, a comprehensive data acquisition plan was crafted and implemented considering: (a) seismic acquisition, (b) drilling, logging and testing several exploratory and appraisal wells, (c) massive rock and fluid data sampling along the reservoirs, (d) execution of one Extended Well Test and three Early Production Systems. Additionally, the basic design of wells, subsea systems and Floating Production Storage and Offloading ("FPSO") provided flexibility to cover remaining uncertainties yet present in the Transfer of Rights ("ToR") scope, which allows up to 3,150 billion barrels of oil equivalent ("boe") to be produced. This led to technological challenges that needed to be addressed during project planning. We believe that the innovative solutions applied enhanced currently available technologies and delivered an important legacy to the offshore oil and gas industry. Finally, the results obtained so far, with the ramp-up of Buzios projects 1, 2, 3, and 4 provide evidence of the successful adopted strategy and reinforce the decision of deployment of a fifth FPSO under the scope of the ToR contract. The strong results of the asset led to the acquisition of 90% of the Transfer of Rights Surplus ("ToR+"), together with CNOOC Petroleum Brasil Ltda. (5%) and CNODC Brasil Petróleo e Gás Ltda. (5%), which now paves the way for a second wave of development, including the deployment of up to seven additional FPSOs.

ABSTRACT Well integrity technologies have been in high demand within the oil and gas industry in the recent years due to two main reasons; Recent incidents and down term in industry. The recent failures and blow out incidents occurring in different parts of the world encouraged new strategies and well integrity management systems to be deployed in order to ensure wells are meeting health, safety and environmental standards. Moreover, the down term in industry caused by relatively low oil price which led oil and gas operators to scale down on exploration and drilling and alternatively work-over existing wells. It is believed that the most economical way to work-over the well is by performing data acquisition first, which enables the work-over team to do an informed decision and tackle the specified problem, saving non-productive time. One of the fast growing well integrity technologies is leak detection. Unlike conventional data acquisition techniques such as corrosion monitoring, leak detection method traces the fluids entering to the well-bore and gives a dynamic image of what's going on in a producing/injecting well. The leak detection is mainly based on passive acoustic measurement, which is typically based on listening to fluid vibration by moving through different aperture sizes, and recorded in different frequencies and amplitudes. Other measurements are recommended to add such as temperature, pressure and multiphase sensors (in case leak is suspected to be inside the tubing). The technology has been used in various locations around the world with challenging environments. The typical and most desired ones are firstly the surface casing leaks where fluids of various types enter into the annuli between casings and build up on surface. Moreover, high amounts of undesired fluids contributing to the production and the source would be hard to identify with conventional technologies.
