Petrel Exploration Geophysics
Unprecedented access to extremely large seismic datasets
It is increasingly important to have an accurate regional understanding of the geology and
regional structure of your basin. Petrel seismic software is specifically designed to take advantage
of the latest advances in PC compute technology, providing unprecedented access to extremely
large seismic datasets while offering a remarkably interactive user experience.
Scalable interpretation at your desktop
Through smart disk roaming technology and bricked seismic rendering it is possible to visualize
and interpret regional exploration datasets in both 2D and 3D at your desktop without the need to
invest in huge amounts of RAM. Users are able to visualize and interpret data directly from the
disk file with a performance quality traditionally associated with applications where data is loaded
into memory.
Parallel processing enables rapid analysis
Parallel processing of geophysical workflows from volume visualization to attribute analysis is
designed to take full advantage of the rapid development of multiprocessor desktop workstations
and provide massive performance enhancements-freeing up the machine and allowing the user to
become more productive.
64-bit for improved performance
Combine the power of advanced disk roaming with 64-bit extending memory for the ultimate
performance when working with large seismic datasets. This improves seismic scalability
especially with networked storage seismic. Single seismic data format for line and volume
interpretation removes the need for multiple geophysical applications.
Benefits
3D surveys and thousands of 2D seismic lines can be visualized together to improve
understanding of regional geology.
Performance and image quality improves with faster hardware and will continue to improve
as hardware develops.
Full integration with reservoir modeling and reservoir engineering domains provides a
complete understanding of your basin.
Exploration scale mapping support.
Automatic fault polygon generation for improved exploration mapping and volumetric
calculations.
Petrel Classification and Estimation
Handle data estimation and forward modeling problems
Neural networks have emerged as proven technology to handle data estimation and forward
modeling problems. The Classification and Estimation module provides an alternative to the
deterministic and stochastic 3D property estimation techniques currently found within Petrel. It
also introduces new workflows for log estimation, property mapping and seismic classification.
Classification and estimation process-how it works
This module gives you access to tools for neural network analysis, enabling you to train and then
create the estimation model object. Data types available for use as input to the estimation and
classification process include:
Well logs
Surfaces with attributes, including seismic attribute maps
Properties, both discrete and continuous
Points with attributes (attributes can be sampled from maps or seismic volumes, points
could also be well tops or point well data)
Predictive modeling
Once the nonlinear functions have been created, the estimation model can be used for predictive
modeling on a wide variety of data types via the appropriate Petrel process for that data type.
The relevant Petrel processes are:
Make well logs - well logs
Multi-trace attribute generation - seismic attribute cubes
Facies modeling - discrete property generation
Petrophysical modeling - continuous property generation
Make surface - surface attributes (including seismic attribute maps)
Advantages
Generalized neural network implementation for the estimation of well logs, surfaces, seismic
volumes and 3D property models. An alternative to geostatistics when there exists a non-linear
relationship between a set of input data and a given output, or when there is no single or set of
two variables that provides an adequate correlation.
Petrel Seismic Interpretation
Combine 2D and 3D seismic interpretations in a unified environment
Petrel seismic interpretation software seamlessly combines the rigorous workflows of interpreting
in 2D with the visual and performance benefits that only 3D volume interpretation can provide.
You also gain the unique advantage of an interpretation environment unified with geology,
reservoir modeling, and reservoir engineering domains, giving the ability to rapidly interpret
seismic data and compare the results with other data in your project. Effortlessly moving from
interpretation to structural model building to property modeling and back eliminates the gaps and
inevitable knowledge and data loss of traditional systems that require handoffs from one technical
domain to the next.
Benefits
Combines visual and performance advantages of 3D seismic interpretation with the
traditional 2D views for accuracy and detailed event picking, enabling advanced 3D
visualization at every desktop
Enables rapid, detailed event interpretation using accurate manual and powerful automated
tracking with a wide range of control and editing options
Offers the unique advantage of interpreting seismic in a truly unified environment
Provides scalable desktop interpretation from regional basin study workflows down to
reservoir detail
2D seismic interpretation
Load SEG-Y format data together with the corresponding UKOOA navigation data into the Petrel
application for comprehensive 2D workflows. Interpret horizons and faults across 2D data with a
full set of interpretation tools and grid directly from within the Petrel application for improved
understanding and mapping.
3D seismic interpretation
Visualize and interpret massive amounts of 3D data directly from your Windows PC without
having to load all the data to RAM. A full range of tools allows you to take a traditional line-by-line
approach combined with the latest algorithms and tools, including amplitude and waveform based
tracking for best-in-class 3D volume interpretation, allowing you to achieve rapid results while
giving you control in more complex areas of weaker signal strength.
2D/3D multi-volume interpretation
It is often necessary to work with multiple vintages and surveys of both 2D and 3D data. Petrel
software makes it easy to interpret across multiple 3D and 2D surveys, either in the interpretation
or in 3D windows, to gain the best understanding in the shortest time. Interpret the same event
across multiple surveys and grid, contour, and map either the whole event or just a part for
individual surveys.
Data management
Today's interpretation projects demand a flexible and dynamic project data management
structure to cope with the amount of data involved. Current projects may cover large regional
areas, thousands of 2D lines with tens of thousands of traces covering hundreds of kilometers,
and multiple 3D vintages and surveys. The Seismic Survey Manager allows you to effectively
manage the 2D and 3D seismic data within your Petrel project, improving the user experience
when working with large amounts of data.
Additional interpretation highlights
Basemap selection of seismic lines, including 2D lines, for display in the interpretation and
3D windows
Mis-tie analysis for correction of gain-, phase-, and vertical mis-ties of 2D data

Composite lines across multiple 2D and 3D surveys for improved regional interpretation
Smart cropping of both 2D and 3D data for interpretation or export
Unified interpretation windows, 3D windows, and base maps with continuous cursor tracking
for improved interpretation and fully flexible interpretation workflows
Intelligent autotracking, including amplitude and waveform based tracking
Tracking constrained by faults, horizons, polygons, dip, and strike
Interactive parameter testing for improved results
Stored parent-child relationship for easy editing and correction of interpretation
Petrel Seismic Attribute Analysis
Enhance traditional seismic information for improved data interpretation
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 workflow editor.
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.
Petrel Seismic Sampling
Generate seismic attribute maps on any 2D surface or average seismic properties within a time or
depth interval.
Benefits
Display any seismic data with a 3D depth converted model.
Import a simulation model into Petrel and quality check it with the seismic data.
Condition your reservoir model with depth converted seismic attributes sampled into the
grid.
Seismic depth conversion
With a simple click, your seismic volume is depth converted according to the velocity functions for
the horizons in a 3D grid. When a seismic volume is depth converted, Petrel will locate the time
horizons and the corresponding depth horizon in the two 3D grids and adjust the Z-position of
each seismic trace. The resulting depth converted seismic will be restricted to the boundaries of
the 3D depth grid.
The depth converted seismic allows the same options as original seismic, including 3D auto
tracking and manual interpretation. You can display the volume in the interpretation window and
create attributes from the depth data.
Quality control
Display the depth converted seismic with property grids or results from simulation to ensure
the quality of the modeling.
Different disciplines can work together on the same interface.
Sample depth converted seismic amplitudes or attributes into an existing 3D grid.
Sampling
Sampling is the process whereby Petrel investigates the attribute values within a grid cell and
populates the grid cells with one attribute value. The algorithms that can be used in this process
are: closest, interpolate, intersection, and exact.
To obtain a realistic and accurate model, the sampled seismic attributes can be used to guide or
condition the property modeling.
