It never ceases to amaze me how adaptable we all are in our ability to not just keep going despite challenges, but to adjust, succeed, and deliver on our promises to clients and business partners.
Within the Petrosys Group, this is clearly evidenced by the level of productivity that has been achieved by our teams, who like many are working from home and have worked tirelessly to develop and produce new software releases Petrosys PRO 2020.1 and dbMap/Web 2020.1, deliver a range of technical and informative webinars, as well as create multiple helpful videos and product articles.
The high level of appreciation for this creative output has been marked in the 5* support feedback rating we have received from our users throughout 2020. It has similarly been very pleasing to see the increase in demand from clients who have been able to take advantage of the work from home initiative offered and the continued engagement we have had with users across all fronts. Your input on future roadmap developments is crucial and many will recognise the results of this feedback in the recent software releases.
Please keep telling us your business needs and drivers for the future of the software and we will continue doing our very best to deliver.
The oil and gas sector continues to face challenging times causing a demand for technology that can enable efficiency and improve workflows. I’d like to take this opportunity to impart Petrosys’s on-going commitment to the industry. We continue to invest organically and beyond in an effort to help companies do more with resources that are scarce.
Petrosys PRO is renowned for its geoscience integration and connectivity with 3rd party sources and this brilliant work has gone from strength to strength with the help of our partners, in recent months evidenced by the addition of the Ellis Palesocan connector. The excellence of the Surface Modeling module keeps shining through with new functionality such as the Fault Clipping Distance controls, meaning more accurate grid surfaces around fault zones, read more about working with faults in, ‘Mapping with Faults using Autotracked Interpretation‘. While our industry leading Mapping simply just gets better and better, you can now directly display PDFs on the map canvas, take advantage of FMI logs in the log signature map displays, and extract raster images directly into grids – see the latest Dear Steve. ‘Using Colour to Communicate‘ explains in detail about the new perceptually uniform colour gradients added to PRO 2020.1.
The Petrosys Client Portal is also a fantastic resource for users and the team has been busy collating pdfs and videos into useful workflows to allow for easy searching of ‘how-to’ documentation, helping you find what you need faster.
The role of sound data management and data quality is the backbone of all that we do and not only have we made advances in the latest release of dbMap/Web 2020.1 with the expansion of the well log viewer to display multi-value log curves such as FMI data; but also to our Prospects and Leads database PLDB, where users can now import data from REP and new data loaders for production data and well test have been added.
Earlier in the year, Petrosys acquired Interica, a respected data management software company with strengths in analysis of the data landscape around many data sources and applications and data archive/optimisation. It has been inspiring to see how smoothly the teams have managed the integration of Interica into the wider group with version 6.2 of Interica OneView released at the end of June. The new ideas, opportunities, and synergies that develop from the wider collective as we build on the collaboration across all sectors of the companies is exciting, the benefits of which to our clients are highlighted already in the existing capability to support Petrosys project archiving. We are now working on ideas to deepen this R&D synergy for client benefits around data landscapes, 3rd party integration, and capturing key knowledge at important project gates and milestones. We look forward to growing and expanding this shared offering and welcome your input to shape the direction.
The innovation keeps coming with the GLOBEClartias team who are doing some exciting work, for example, the AI based methodology recently released for denoising seismic records, with the new DENOISE_TF module. The latest version of GLOBEClaritas V7.1 is out now, along with completely re-vamped tutorials for the new version. It is easy to see why GLOBEClaritas is fast becoming a leader in seismic processing software through continuous and frequent software releases and new features.
We are also extremely proud of the client feedback received for our GPinfo products, maps, and the great service they deliver on a consistent basis. To me it demonstrates the day-in-day-out commitment to data management excellence and map product quality – we practice what we preach at the Petrosys group when it comes to delivering quality data frequently! I find the quotes from clients both humbling as well as motivating, they drive us to serve, to innovate, and to continue to deliver on a monthly/quarterly and yearly basis. It is clear the products the GPinfo team provide are extremely valuable to existing and prospective investors in the Australia-Pacific region.
From everyone at the Petrosys group, we encourage you to contact us if you need help, we thank you for your continued support and we look forward to the days we can meet again in person.
I hope you, your colleagues, and families keep safe and well. If you have questions or need any help – please just ask me.
Q. Dear Steve… Can I display raster images as a grid in Petrosys PRO?
A. Yes, now you can!
With the release of Petrosys PRO 2020.1, users are now able to display raster imagery with XYZ data as grids in Mapping and, in general, use across the software as part of any workflow. The new functionality will allow users to quickly add and use these types of georeferenced images into their maps and workflows without having to import them into one of the traditional grid formats.
To be able to directly display raster images as grids, two conditions need to be met:
- Images need to be georeferenced
- A ‘digital value’ needs to be assigned to each pixel in the image. This is the value that would be used as ‘z’ when displayed as a grid.
For users to take advantage of this functionality in Petrosys PRO Mapping, all they need to do is to follow the same workflow to display any grid in PRO:
- In Mapping, go to Display > Grid… or click the relevant icon.
- Set the data source to ‘Raster file’.
- Point to the raster image.
- If needed, override the CRS. This option is available as not all raster formats store this info.
- Then, tread as any other grid and set the parameters accordingly. Note you will be able to generate contours ‘on the fly’ from the Contours
A panel like the below one will be presented. Checking and understanding the raster metadata is important as users need to be aware of which ‘band’ contains the relevant info to be displayed.
To query detailed grid statistics, click on the ‘information’ icon on the right side of the statistics section. A panel like the below one will be displayed.
In addition, rasters can also be displayed as grids using any of the display options you would have for any grid: colorfill, values, sun shaded, highs and lows, and even orthocontours.
The use of raster imagery as grids is not only restricted to Mapping but can be used across the software both in Surface Modeling and the 3D Viewer.
In the below screenshots from Surface Modeling, it can be seen that in any workflow where there is the ability to select grids in various formats, the ‘raster file’ has now been added as one of the input options. The ‘Surface Modeling’ application can also now import raster files with non-square cells.
And same goes for the 3D Viewer…
File types supported include DEM, GeoTiff, ECW, Arc BinaryGrid, ERDAS Imagine and BIL files.
Read about more new functionality in the release notes or users can find numerous workflows in pdf or short video format are available in the Client Portal.

Interica OneView provides a clearer picture of the Petrosys PRO Map and Project data landscape
Petrosys acquired Interica in early 2020*, as an oil and gas sector leading, subsurface data management software company, and as Petrosys CEO Scott Tidemann explained, «Collectively we have industry leading 3rd party data connectors and R&D experience with a broad range of oil and gas subsurface knowledge.»
Upstream Oil and Gas Companies generate vast volumes of complex data through the use of diverse petrotechnical application workflows. These applications range from seismic processing and interpretation through to full static and dynamic reservoir modeling, with multiple discipline led workflow applications in between. The analysis, interpretation, and modeling completed through these applications become the Intellectual Property of the Oil and Gas company. This ultimately is the foundation of their value and what differentiates one company from another.
Petrotechnical data volumes continue to grow rapidly. It is critical for companies to design & deploy comprehensive and standardised data management strategies that result in a holistic view across this core and complex data landscape. Torbjørn F. Folgerø, SVP, and Chief digital officer at Equinor recently stated “Our operations generate huge quantities of data—26 petabytes per year, 50 times the US gene database. It’s not improbable that we will reach 2500 petabytes by 2030.” (1)
Interica OneView delivers a unique, single pane of glass view across the entire petrotechnical application environment. Dynamically liberating rich data and metadata from applications, giving immediate insight into application, data, and user footprints. Interica OneView also offers out of the box connectivity to 35 petrotechnical applications from companies such as Schlumberger, Halliburton, Petrosys, IHS, CGG, Paradigm, Eliis, and many more. The metadata and spatial data collected from these applications is normalized to enable querying across all applications, additionally, any application specific metadata to also collected. This enables:
- Live data discovery – quickly ascertain data usage by application or user, detect data duplication across projects, understand quality, and explore data lineage all from a single interface or set of consistent APIs.
- Automated actions – archive projects at agreed milestones and/or migrate projects & data when inactive, or support data migration projects. Build and simulate policies and their effect, based on the collected metadata. For example, to archive all data for a given field or license, to migrate all active Petrel data to file storage and all inactive to object storage or to archive all data relating to users that have recently left the organization.
- Easy Restore – When organisations choose to move or archive these datasets to low cost object/blob storage, they can use the metadata to explore the project content without needing to bring project or dataset back online first. This reduces cost and results in the restoration of datasets users know they need – with confidence.
Current OneView Integration with Petrosys PRO
Interica OneView quickly identifies all Petrosys PRO projects that have been created within an organization before collecting any available metadata, spatial data, and images that are available within the projects. This includes Petrosys PRO reports, map sheets, project summary information, and associated geospatial and CRS data.
Users can quickly see all the data sources that were used to create their Petrosys PRO project, captured from an audit trail available in the summary information. All information is stored in Interica OneView and is continually updated with any subsequent scans.
Users can query their Petrosys PRO projects individually or in the context of other applications and datasets and use the Interica OneView charting, spatial, and query tools to analyse their Petrosys PRO data landscape.
Interica OneView archives your valuable Petrosys PRO maps at key milestones in your project’s lifecycle. These milestones can include: reaching an important conclusion, completion of the project, a major joint venture investment, or as part of reserves redetermination. If referenced data is held externally to the project in applications such as Schlumberger Petrel, IHS Kingdom or other 3rd party systems Petrosys PRO connects to, these references are stored with the archive.
The Interica OneView capability can work in harmony with the Petrosys PRO project crawler – a utility for extracting and collating summary information about large collections of Petrosys PRO files, such as all the grid files in a Petrosys PRO project. Regularly running the project crawler and keeping the associated metadata reports, will enrichen the data knowledge and information archived for Petrosys PRO projects (helpful on future restore) when used in combination with the Interica OneView setup. Read More about the Petrosys PRO Crawlers.
Looking ahead. The roadmap for how these trusted technologies could evolve – input welcome!
The team is working collaboratively on the vision for extension of the present capability of Interica’s Petrosys PRO connector, with a focus on:
- A one button press intelligent map archiving capability – to help archive associated map and workflow data. The focus being to deepen the capture of maps at milestones, key audits, for JV meetings, and similar mission critical processes.
- An automated map archiving capability – tying into the popular Petrosys PRO surface modeling and volumetrics workflows. In particular, this is focused at the capture and management of deterministic and stochastic resource assessments.
- We are also considering the value in a wizard that guides the selected capture and archiving of a series of project maps and milestone information. Both to help feed a “map catalog” understanding of key knowledge and ensure vital data is effectively managed at project milestones.
Naturally, we anticipate making the data landscape, analysis, and archive tools richer through time based on active client needs and inputs. Our team is gathering the desired project needs now to plan the next innovation steps. If you have ideas and requirements to share or are interested to outline business challenges associated with this initiative – please pass them along to the teams.
Contact your account manager and our technical support staff to find out how Interica OneView can further support your organisation’s challenges or to share your input on the roadmap.

Susanna Willan, Petrosys
Improve your mapping standards by taking advantage of the latest scientific colour gradients. We have added a number of perceptually uniform and ordered gradients to new release Petrosys PRO 2020.1, created by Fabio Crameri – a data visualisation scientist.
When assigning a colour gradient to a subsurface map, do you think about how this gradient is interpreted? Or how accessible it is for all users? Or do you apply the prettiest colours (I use this term loosely) and click publish? Research on data visualisation and scientific colour gradients has been carried out for decades and numerous authors have lamented the misuse and overuse of the rainbow colour palette, also known as the jet colour palette.
Despite this, the application of appropriate colour gradients by many geoscientists has lagged behind. I must confess that I was also late to the party. Why is this? Perhaps there has been a misconception that using the full RGB spectrum for subsurface maps will highlight the detail required for interpreting geological structures? On top of this, the rainbow colour gradient has also stubbornly embedded itself as the gradient ‘default’ for numerous software vendors. We are creatures of habit and this visual familiarisation has led to an acceptance of the ‘norm’. All I can say to that is STOP. Explore your data and explore your options, don’t accept the default just because it’s the default. Please read on…
So why is the rainbow colour palette bad for subsurface mapping?
We use visualisation methods to understand trends, patterns and structures in the underlying data. For geoscientists, colour is one of the most powerful techniques for visualising the subsurface geology in depth/time maps. Colour (along with contours) is used to quickly identify structural highs and lows, erosional and depositional features and stratigraphic thickness changes. On top of this, geoscientists use maps to analyse attributes such as porosity and net pay. Therefore, a colour palette should:
- reflect the data distribution in a uniform and ordered manner
- be accessible for those who are colour blind
- be legible in black and white print.
The rainbow gradient does none of these things. Have a look at Figure 1. Do you find yourself focussing on specific parts of the spectrum, such as the sharp contrasts at the cyan and yellow wavelengths? These are caused by a non-linear increase in brightness and result in artificial boundaries forming where none are present in reality.
Figure 1: Rainbow gradient
To illustrate this further I will compare three subsurface grids. Each grid covers the same area at a different scale. They have been displayed with the rainbow gradient and a perceptually uniform and ordered gradient. In the small-scale maps that show the regional structure of the Top Latrobe grid (Figure 2), the rainbow gradient introduces a significant amount of ‘banding’. Within these bands, our eyes are desensitised to smaller changes, especially within green and yellow wavelengths. This hides the detail that is otherwise picked up by the lapaz gradient, such as the sinuous channel that trends NW-SE before reaching the basin.
Figure 2: Top Latrobe regional grid displayed in the rainbow gradient (left) and the lapaz gradient (right).
On the medium-scale and large-scale maps, the rainbow gradient introduces two artificial boundaries to the subsurface. One has formed where the cyan and dark blue hues meet and the second where yellow and red hues meet. These unequal contrasts occur even where the contours indicate that there is little topographical change (Figure 3).
Figure 3: Intra Flounder grid displayed in the rainbow gradient (left) and the bamako gradient (right).
At prospect scale (Figure 4), this distortion makes it harder to discern the size and scale of potential structural traps. As a first pass assessment, I certainly feel more confident identifying the lowest closing contour in the right-hand map. Or rather, my eyes can interpret the subsurface geometry more accurately.
Figure 4: Intra Flounder grid displayed at prospect scale in the rainbow gradient (left) and the batlow gradient (right).
Improve your mapping standards
To avoid data misrepresentation, I would encourage you to look beyond the default colour gradients used by many software vendors. For PRO 2020, Petrosys have added a number of sequential and divergent gradients, created by Fabio Crameri. These gradients are perceptually uniform so they do not distort the underlying data and they are perceptually ordered so you can see which direction the data decreases and increases. They are suitable for people with colour vision deficiencies and they can be read in black and white prints.
So the next time you pick up a Petrosys PRO project, have a look at the new gradients added to our Gradient Selector and test these out to see how accurately they pick up erosional and structural features. Try not to settle for the default, go forth and create some beautiful scientific maps.
Figure 5: New gradients available in Petrosys PRO.
I want to finish with this last tip. In PRO, each new gradient is set as dynamic by default, meaning that it will automatically fit the range of the gradient to the minimum and maximum value in the input data. However, you can also fix the gradient to a user-defined minimum/maximum, or clip the range to the map extent. This is a useful function when setting a small map extent over a large regional grid. The colour gradient will reset when the map extent is moved and will display the detail required for a smaller data range (Figure 6).
