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.

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!

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.
