The attribute generation process contains a library of different single and multi-trace seismic attributes for display and use within the seismic interpretation workflow. Seismic attribute analysis helps to enhance information that might be subtle in traditional seismic, leading to a better interpretation of the data.
Multiprocessor capability for rapid attribute calculations
Take advantage of multiprocessor desktop workstations to run attributes faster and in the background, freeing up the machine and allowing the user to be more productive. Optionally, generate attributes remotely on a Linux cluster and instantly review and use the results back in Petrel, reducing the time taken from hours to minutes and allowing more informed decisions to be made quicker.
Genetic Inversion
Seismic reflection data is the primary input for resolving structural and stratigraphic variations between points of well control in the majority of the world's sedimentary basins for the exploitation of hydrocarbon resources. Petrel brings a step change to this process with the fully integrated genetic inversion algorithm allowing geophysicists and geologists to more accurately predict inter well properties from seismic inside of Petrel. Horizon autotracking options allow you to pick directly on the impedance volume or it can be used as an input in the enhanced geobody isolation and extraction process for improved reservoir characterization.
Surface attribute library for rapid prospect identification
A new attribute library gives the user access to over 40 attributes that can be instantly calculated directly at interpreted events, on nearby uninterpreted events, or between events. This allows the interpreter to extract the maximum value from seismic data by providing more detail on the subtle lithological variations of your reservoir without having to generate new seismic attribute volumes, speeding up the prospect identification and mapping workflows.
Capture and repeat attributes to share knowledge
Attribute calculations can be built into the Workflow Manager and repeated across different events or fields to share knowledge between teams and capture parameters for best practices.
Benefits
Structural attributes can help accelerate the task of picking horizons and faults.
Seismic attributes related directly to log and rock properties in the model can take advantage of the integrated petrophysical and facies modeling in the Petrel application, thus defining a better model and reducing uncertainty.
A wide range of attributes and combinations of different attributes can be used to identify stratigraphical and structural events.
Parameters can be optimized using a real-time probe or slice. You can then calculate the entire volume or set up a series of calculations using the Process Manager.
Instant surface attributes can be generated without having to generate seismic attribute volumes, increasing understanding, saving time, and enhancing the mapping workflow.
Multithreaded and background processing increase performance and speeds up the calculations, enabling the user to be more productive.
Remote attribute generation on a Linux cluster reduces the time from hours to minutes and allows attribute volumes to be shared among multiple users.
Enhancing seismic workflows
A variety of new workflows can be derived using attributes to
precondition the data for better horizon autotracking
enhance the fault signature of the data by calculating variance or chaos, or by filtering structural smoothing with the edge enhancement option
precondition the data for seismic facies extraction using relative acoustic impedance or the chaos attribute to isolate salt bodies
combine attributes and generate users' own attributes using the seismic calculator.
