Overview

Petrel™ data analysis enables interactive analysis of distributions and trends and their relationships across all data types. Histogram, function, and stereonet windows—as well as the Petrel data analysis process—are provided for analyzing upscaled well data and grid properties.

Identify trends and anomalies in data sets with cross plotting tools and interactive filters.

Create filters in stereonet, histogram and function windows and apply to data in 3D and to other 1D plotting windows.

Following property population, assess reservoir model quality; HCPV oil property and its associated oil volume height map.

Analyse distributions, remove trends, and set up transformation sequences in preparation for modeling workflows.

Experimental variogram computation on vertical, major and minor directions, includes nested variograms.

Achieve realistic final facies fractions in your reservoir model through the adjusted vertical proportion curves.

Check the relationship between sampled seismic data and upscaled facies logs, and create probability volumes for use in modeling.

Applications

Interactive variogram analysis

Benefits

The interactive variogram analysis includes options for initial search-cone parameter suggestions and fitting the variogram to the regression curve, with the ability to also build nested variograms. Detailed analysis can be saved for each property for direct use in the modeling processes. Sensitivity plots enable users to compare the impact of each uncertain variable in a risk-analysis context.

Evaluate fractures with the stereonet window, display the rose diagram and filter fractures by type, well, dip angle, dip azimuth.

Features

Import and export vertical proportion curves for specific facies and optionally fit all vertical proportion curves to the histogram for all zones and all facies automatically and all at once
Prepare input data using transformation sequences (input/output truncations, scale shifts, and distribution shape options complemented by tools for trend fitting and removal) prior to petrophysical modeling
Generate variogram maps from your input data to determine major and minor directions of anisotropy
Use the declustering option for data analysis of horizontal or clustered wells to honor global facies and petrophysical proportions
Display rose diagrams and analyze dip and azimuth data in stereonet windows
View simulation summary results using crossplots and histograms in the function window
Create functions from crossplots and create raw crossplots and distribution functions from histograms
