Advanced Property Modelling in Petrel

•This is a 4 day training course suitable for explorationist. The course provides a detailed overview of geostatistical theory as well as practical experience in implementing facies and petrophysical modelling in Petrel.

•On completion of this course, participants will have built competence at a skilled application level in the key geostatistical methods that play such a major role in modern reservoir characterisation, then applying them through practical exercises using the Advanced Property Modelling modules of Petrel.

Prospect Evaluation Methods: Volumetrics and GRV

•A 3 day course for all subsurface disciplines. The course covers the elements of uncertainty including velocity, seismic interpretation and depth conversion and the use of geostatistics to evaluate gross rock volume uncertainty. The hydrocarbons in-place calculation is examined and the uncertainty associated with modelling the petrophysical, fluid and other parameters described.

•Play and prospect risking is also considered and guidelines proposed to assist in utilising database, historical, basin and global success statistics in your analysis. Parameter dependency is considered and also analysis of the results in the context of portfolio management. The course includes hands-on practicals on geostatistics, spillpoint and volumetric uncertainty and prospect evaluation and risking using Earthworks HIIP™ software.

Petrel Depth Conversion

Depth conversion (domain conversion) of seismic time interpretations and data is a basic skill set for interpreters. However, there is no single methodology that is optimal for all cases since the available seismic and geologic control varies in quantity and quality within each project. To design an effective approach to depth conversion, the first part of this course prioritizes understanding the nature of velocity fields and practical approaches to velocity representation. Next, appropriate depth-conversion methods are presented in case history and exercise form. Single-layer and more sophisticated multi-layer approaches are reviewed, along with depth-error analysis and the impact on formation top prognoses and volumetrics.


Depth conversion must also embrace the process of database validation. Poorly positioned wells, miscorrelated horizons, and inconsistent formation tops can introduce distortions in the implied velocity field and result in false structuring. Database validation is addressed via the formation of synthetic seismograms to confirm horizons correlation and the formation of basic Seismic Time vs. Formation Top QCs.


Course on depth conversion will also be applied to validating the ties between the formation tops and the surfaces used for calibration. This is particularly important during anisotropic depth migration where inconsistencies between well control and the seismic interpretation impact the estimation of anisotropic parameters, resulting in a compromised depth image.


This course emphasizes the formation of velocity models consistent with the well control. This is in context to creating Petrel Models suitable for reservoir simulation employing depth-calibrated inversion and other attribute cubes precisely integrated with the well information.

Velocity Modelling

•The Volume Velocity Modeling for Petrel  presents a workflow for building a geologically consistent velocity volume integrating the detail of the well velocity measurements with the spatial density of the seismic velocities.

•The course covers a combination of theory and practical application of volume velocity modeling in Petrel

•Highlights of the course include:

•Reduce the risk on exploration and development projects by building a solid velocity model integrating of all the available velocity information in a 3D geologic model using geostatistical tools.

•Reduce the cycle time using Petrel workflow editor automated process.

•A systematic, repeatable, auditable approach for increased confidence in results

•Expertise beyond standard training

•Validation of the workflow on client data

•Adoption of the technology facilitated by Guru supported delivery

Petrel property Modelling

•The Petrel Property Modeling course is intended for the user with fundamental Petrel modeling skills. The course covers basic geostatistics, data preparation, data analysis, facies and petrophysical modeling. You will learn different ways to create property models and how to condition models to existing models and secondary data. This course guides the user through concepts, algorithms and software functionalities in property modeling.

•The first part of the course focuses on the usage of  basic geostatistical tools, through data analysis.  Also pre-modeling processes concerning well data preparation will be covered. Also here we will look into the first step of the property modeling workflow: upscale well logs to create single property values at well location for each cell. This will create hard data that will be used to populate the 3D grid with either deterministic or stochastic algortihms.

•The second half of the course focuses on facies and petrophysical modeling workflows using stochastic methods as well as covering the usage of Kriging for continuous properties. Implementing Data analysis results and using secondary data to constrain the result will also be shown.

Earth Model Building

•This five-day hands-on course introduces the geoscientist to the functionality of the WesternGeco Petrel plug-ins that are part of the Omega Earth Model Building Bundle. This is primarily a software course where students will use practical exercises to explore the earth model building workflow.
