Working with color blends in Petrel®

When working with color blends of any type, it is best practice to interpret directly in GeoTeric to maintain quality and color intensity.  As third-party software differs, quality and visualization will often be impacted following blend transfer.  However, we do understand there is often a requirem...

Working with color blends in Petrel®

Posted by Andrew Pomroy on 19 Mar 2019

When working with color blends of any type, it is best practice to interpret directly in GeoTeric to maintain quality and color intensity.  As third-party software differs, quality and visualization will often be impacted following blend transfer.  However, we do understand there is often a requirement to transfer color blends to Petrel® and therefore we’ve explored how color blends can be visualized and used in Petrel.

GeoTeric 2018.2 - new features

Posted by Andrew Pomroy on 21 Jan 2019

Auditable volumetrics for fast and effective evaluation of hydrocarbon resources

Within the newest release 2018.2, GeoTeric is enhancing the exploration workflow by introducing a ‘Volumetrics’ tool which allows calculation of oil and gas resource estimates at any point during horizon interpretation and editing.  Results can be saved within the project or into an external file which can be updated following further data acquisition and/or refinement of the interpretation.  Continue reading for a brief introduction to the tool and be sure to download GeoTeric 2018.2 today!

Screen anomalies with RMS amplitude

Posted by Luis Gomez on 31 Oct 2018

For a faster way of screening anomalies to confidently interpret your geology, GeoTeric incorporates RMS amplitude calculations in the iso-proportional slicing tool and also allows the creation of a volumetric RMS cube using processes and workflows.  Learn more and follow our step by step guide to create an RMS volume in your GeoTeric project.

Transition of rock properties in Validate

Posted by Ryan Williams on 17 Oct 2018

Within GeoTerics’ Validate module it is possible to define rock properties from well logs to generate geologically accurate models. Once accurate rock properties are defined in a model, it is important to accurately replicate the geological scenario for which the model is testing. In some cases, using defined rock properties is not enough detail to replicate the geological depositional environment. To increase the accuracy of the model design it is possible to transition rock properties from one type to another.

Visualising Fault Trend Orientation

Posted by Randy Hee on 11 Oct 2018

One way to incorporate information from FMI logs into GeoTeric is to classify fault by their trend (orientation along strike).  This will allow the user to quickly correlate the orientation of open fractures/faults from FMI logs to the seismic volume, gaining a better understanding of the direction of these fractures/faults.

Getting started with wedge models in Validate

Posted by Rachael Moore on 04 Sep 2018

GeoTeric 2018.1.2 introduced the ability to create a wedge model in Validate to estimate thickness from the RGB blends. Frequency responds to changes in lithology, which can be modelled using the Validate Layer Model, but also to changes in thickness.  By creating wedge models, interpreters are now able to model thickness changes in an interval and determine which colours represent different thicknesses.

Fault Enhancement - the fine print in Fault Expression

Posted by Peter Szafian on 07 Aug 2018

One of the most popular applications of GeoTeric’s Reveal module is the Fault Expression. Its example driven framework enables rapid optimisation and co-visualisation (CMY blending) of three independent edge attributes ensuring that faults of different sizes and seismic expressions are identified and detected with confidence. 

A great value of the Fault Expression tool is that the effects of the different parameters can be immediately assessed: there is no need for extensive testing and comparisons, because after adjusting the filter footprints, the resulting changes are seen in the preview window. However, there is a set of parameters, which are hard wired and cannot be changed. These are the fault enhancement filters, mentioned in fine print in the Detect tab of Fault Expression. Switching between the different preview swatches, we see that the detected faults are different, even without changing the detection filter parameters. So, what do these numbers in the brackets mean?

Validate Part 2: Fluid Substitution and Rock Properties Settings

Posted by Andrew Pomroy on 25 Jul 2018

This is the second part of a two-part (part 1) blog post focusing on ‘Validate’, GeoTeric’s seismic forward modelling module that recently became available with the release of 2018.1. The tool is meant for interpreters to be able to easily test hypotheses by creating models that can be matched back to frequency decomposition results as well as reflectivity data.

Validate Part 1: Creating a Simple Forward Model to Test Depositional Scenarios

Posted by Andrew Pomroy on 13 Jul 2018

This will be a two-part blog post focusing on ‘Validate’, GeoTeric’s Seismic Forward Modelling module that recently became available with the release of 2018.1. The tool is intended for interpreters to be able to easily test hypotheses by creating models that can be matched back to frequency decomposition results as well as reflectivity data.
This week’s post works through a simple example of testing a hypothesis using Validate. In the next post, we will go over some more advanced topics.

We begin by focusing on the Eskdale reservoir in offshore Australia’s Exmouth Basin. This field is comprised of deepwater channel sands compartmentalized by faults. We’ll be looking at the first exploration well, Eskdale-1 (Fig. 1), which found only residual oil in a 75-meter-thick sand package.

Figure 1: Gamma Ray and acoustic logs over the Eskdale reservoir in the Eskdale-1 well. Note the change in acoustic impedance at the “Intra_reservoir” marker.

Figure 2 shows a map view of the frequency decomposition RGB colour blend draped 10ms below the top of the Eskdale member. The Eskdale-2 well was drilled in a separate fault block and found economic oil, so the task of defining the reservoir extents both in terms of reservoir quality sand and fluid content becomes critical if the field is to continue to be appraised and developed. As evidenced by the map below, GeoTeric’s Frequency Decomposition attributes reveal many aspects of the depositional system. But the question has always been, “what do the colours mean?”. Validate can help answer that question.
