Preliminary diagnosis and ranking for hydrocarbon exploration areas: geological, environmental, metocean, socioeconomic and legal aspects.
CEGeo is offering a product to help Oil & Gas Companies to fill information gaps, assisting with approaches to tackle
exploratory and environmental challenges
The decision to acquire concession blocks offered by the Brazilian Oil &Gas Agency (ANP) is full of complexities, requiring detailed analysis of all inherent aspects. Recently, some companies acquired blocks and did face strong dificulties on the licensing processes, on the interpretation of geological data, an on the gathering of environmental data, among other issues. Some of them had to return the concession to ANP or did spend non-planned budget due to a lack of knowledge of the acquired area.
Based on that scenario, CEGeo is offering a product to help Oil & Gas Companies to fill information gaps, assisting with approaches to tackle exploratory and environmental challenges.
The product aims to give a preliminary background on the initial process of the evaluation of the potential of a given petroleum system, providing to the client a kind of ranking of a given area or block, in terms of its geological, petroleum occurrence, environmental, legal and logistic aspects, assisting E&P companies on its decision process.
Ideally, the product is offered as a package, but the distinct modules which are part of the product can be delivered separately.
Contents of the Diagnosis
1. Geological analysis and petroleum system
This item presents the general characteristics of the area: location, area and basic infrastructure, drilled wells and its classification ; list of geological and geophysical data available; well logs, geochemical data, paleontological data, seismic, gravimetric and magnetometric data. The general overview of the geologic context of the area will be addressed, with the integration of stratigraphic and structural analysis, and the related exploratory plays. The petroleum systems and its components will be provided: source rock, reservoir rock, seal rock, trap, and migration pathway. The hydrocarbon occurrence and the presence of development and production fields in the area will be discussed. Depending on the available data, the petrophysical analysis of the well will be performed, showing the petrophysical parameters of the hydrocarbon resorvoirs: porosity, permeability, fluid saturation and pore pressure. As a result of the geological analysis of the petroleum systems, a report will be provided, including a extensive technical document and an executive summary, maps, geological sections, composite and petrophysical logs.
