For many geologists, drilling with resistivity tools means losing the ability to make interpretations in-house. Using StarSteer, the first geosteering software with a Resistivity module, this webinar will demonstrate how you can use your data to make vendor-independent and user-friendly resistivity interpretations.
In conventional, heavy oil or carbonate reservoirs, when the Gamma contrast in the target is muted and unsuitable geosteering, or when exiting the target may lead to a sidetrack, additional logs such as Propagation Resistivity may be used.Resistivity interpretation technique is different from GR as it cannot be directly compared with the Typewell due a number of physical effects. StarSteer allows users to easily model boundary/shoulder and proximity effects with polarization horns, as well as the anisotropy of the formation.
StarSteer’s forward resistivity modeling is the fastest on the market due to parallel processing calculations. The Earth Model feature allows users to create a cross-section and populate it with the resistivity properties; additionally, it is the only geosteering software with a resistivity inversion module, regardless of the tool provider. Real-time resistivity logs can be streamed directly into the software to have the distance to boundary calculated for real-time, proactive decisions.

The Petrosys PRO 2020.2 release builds on the collection of new and enhanced features in PRO 2020.1, across Connectivity, Mapping and Surface Modeling. Petrosys PRO 2020.2 delivers the latest new functionality while development and improvements to existing features continue to provide our clients with high value in their software investment. The key highlights of Petrosys PRO 2020.2 are:
Image Augmented Line Tracing in the Spatial Editor
Digitizing contours, faults and other linear features from scanned or published map images has become a lot more productive through the introduction of a ‘raster tracking’ feature that lets the user track lines on an underlying image.
Georeferenced images are opened in the Spatial Editor
With ‘raster tracking’ enabled the tracing cursor looks for lines as it is moved across the underlying image and turns into a ‘hand’ when a line is detected.
Operator can click on point further along the line and they system will auto add the recognized line segment from image being digitized.
Tracking is enhanced by restricting line recognition to a specific colour.
Raster tracking significantly improves line tracing productivity, allowing legacy maps to be converted into better surface models in less time.
Display of PDF’s enhanced with georeferenced & layers
The Display/PDF option has been enhanced to support display of PDFs that contain georeferencing information. These PDFs can now be displayed in the correct spatial locations on the map.
In addition, where a PDF contains layered information, the Display/PDF option now supports the explicit selection of these layers for display. The existing map based PDF display remains available where georeferencing and layering is not captured in the PDF to be displayed.
Now with support for Perforations from the Petrel Global Completions folder.
Development teams and reservoir engineers will benefit from a new Mapping/Display/Wells tab to add Downhole Data to their maps.
Perforations can be displayed along the entire borehole, or between tops; and there is an option to annotate the measured depth at the start and end depth of each perforation.
Ellis PALEOSCAN™ Now supports writing grid data and reading culture data
Petrosys PRO enables data integration and exchange across a wide range of subsurface applications and databases. Our simple and intuitive direct connections allow geoscientists to effortlessly combine data from numerous sources, enhancing the potential for discovering new opportunities.
PaleoScan joined the list of 3rd party applications in Petrosys PRO 2020.1 and this connection continues to expand in PRO 2020.2 with the addition of support for reading polyline Culture data in the Mapping, Surface Modelling and Spatial Data Translator applications.
Culture data stored within PaleoScan project can now be directly displayed on a Petrosys PRO map.
Users have full control over the styling, annotation and attribute filtering and can take advantage of thematic mapping functionality.
In Surface Modelling, PaleoScan Culture data can be used to clip grids and provide boundary outlines for volumetric calculations.
PaleoScan Culture data can be converted into different file formats using the Spatial Data Translator, reducing data management challenges if working in a multi-platform environment.
INTERICA ONEVIEW™ Archiving Intergration
Petrosys PRO now includes a direct link to Interica OneView™. This allows for Petrosys PRO projects cataloged by OneView™ to be archived directly from within Petrosys PRO. Additionally, a quick-link to open your OneView™ instance has been provided for more advanced project cataloging, search, archival, and retrieval tasks.
SEGY Export of Stacking Velocity Data
Petrosys Pro supports reading stacking velocity data from different sources: SEGY files, SDF (Petrosys Seismic Data Files) and text files using various formats, also supports writing stacking velocity data back to SDF and text files.
Writing stacking velocity data back to SEGY is added in 2020.2 to make it possible to use generated SEGY file in third party packages such as DUG Insight.
Output SEGY can be a single 3D SEGY file or a group of 2D SEGY files under a specified folder.
Generated output SEGY files will be in revision is 1 using a 4 byte IEEE Floating numbers, all traces have the same sample rate and sample length.
If the input stacking velocity data is not regular i.e. traces have different sample rates resampling using linear interpolation is done prior to writing to output SEGY file to ensure all traces to have the same sample rate.
Padding is done by using the last velocity value to ensure all traces have the same number of samples.
Petrosys were pleased to be invited to present the paper, ‘Can Elasticsearch help us access large Oil & Gas datasets more efficiently?’ at the recent Society of Petroleum Data Management (SPDM) virtual conference.
A few months ago, our development team were given time to spend on ‘creative innovation’, with the opportunity to work freely on a project of their choice that they felt would offer the most value to our clients. Prompted by some ongoing work with a few clients – we have been using Elasticsearch to overcome the challenges when trying to make sense of decades worth of unstructured reports, documents, and generic files, in an effort to get the data easily into the hands of subsurface technical teams – Data Management Product Manager Brad Rymer decided to investigate different ways of loading data from multiple sources, further evaluating the capabilities of Elasticsearch.
The world’s leading open-source search and analytics solution, Elasticsearch, could help improve the performance and intelligence of Petrosys’s current ability to find, categorise and visualise unstructured data on oil and gas datasets. Delivered at the SPDM conference by Paul Gibb, Petrosys Business Development Manager, we think it made for an insightful presentation.
What is Elasticsearch?
Let’s start off by briefly introducing what Elasticsearch is for those who haven’t heard of it. If you go to their website – https://www.elastic.co/ you’ll see, Elasticsearch helps all industries explore and analyze very large datasets. Elasticsearch is not a replacement for SQL Server or Oracle, it’s a complementary tool specifically designed to do fast searches of large datasets, be it structured or unstructured text, numerical data, or geospatial data.
Without the traditional burdens of relational databases, Elasticsearch is fast and scalable – running on a single server or across multiple machines on multiple nodes to solve large data management challenges.
In summary, Elasticsearch won’t be able to do everything to overcome the challenge, but it will improve the performance and efficiency of working with the large datasets involved.
The problem – Where is all the data?
Petrosys has already developed a crawler to find data, turn it into a series of records, map data types to an object, and extract the content of the files. However, before we look at how Elasticsearch has made this process more ‘intelligent’, let’s go through the problem we’re trying to address and the methods currently being used to solve the issue.
Following many years, decades, of interpretation and analysis, with IT system upgrades, evolving file formats, increased capacity to store more information, mergers and restructuring; we now have unmanageable volumes of data in our industry and there is a risk of critical knowledge being isolated or lost forever.
The challenge for data managers, geoscientists, and engineers is:
to be able to quickly find trusted information
to better understand what data exists and is available
to know if we have duplicates that we can remove to help improve the data resource
to implement a system that does all of the above while reducing the need for people to manually review each record
Managing unstructured data, such as well reports, seismic data acquisition, and processing documentation, in-house or external evaluations, and analysis, commercial reports, presentations, can present a sizeable challenge. Exploration teams can hold tens of millions of files of various formats, in many different folders where ownership and access is complex.
A significant proportion of the data comprises duplicates or working and final versions and the creator/owner of the data may have long since left the company.
For example, imagine you are evaluating a prospect near to the ‘Parara-1’ well which was a successful exploration well. Parara-1 was drilled 15 years ago and over those 15 years, your company has accumulated well reports in Word format, geological presentations in Powerpoint, production data in Excel, and core photographs and reports in PNG and PDF formats (i.e. in a variety of ‘unstructured data’ formats). Parara-1 has also been referenced in many other more regional geological reports which discuss why this well was successful and how this relates to the prospectivity of the region.
Some of the reports are on your ‘go to’ share drive. Some are in paper copies with important geological sketches. Some are in user folders. Some are in file systems used by engineers. Some are on older file systems that are no longer used.
You cannot go and ask the team who planned well Parara-1 because they no longer work at your company. In summary, you have a lot of data about the Parara-1 well that you need access to if you’re going to fully understand how risky/lucrative your prospect is but you have no idea where it all is, if you’ve managed to find it all or if you’re looking at the latest version of each file.
The Solution – Petrosys Intelligent Search
As mentioned, Petrosys has already developed a solution that finds, categorises, and visualises unstructured data. With the addition of Elasticsearch within this cataloguing workflow, shown below in Figure 1, the solution is now being referred to as ‘Petrosys Intelligent Search’. The purpose of Petrosys Intelligent Search is to derive better search results from the various data sources and to see a breakdown of document types.
Figure 1: An overview of the 3 steps of the Petrosys Intelligent Search
read data from various sources
transform the data into common objects, over which you scan the content (using Optical Character Recognition if required)
convert the data into a compatible output format for Elasticsearch
Elasticsearch is then used to work through the data provided and begin the classification and categorisation of documents. At this stage, Data Managers work to improve the data model so that subsequent iterations of the workflow improve the classification and categorisation results. “Elasticsearch is where the indexing, search, and analysis magic happens.”
(often run concurrently with step two) the results of the classification and categorisation of the data can be viewed in the Petrosys Records Management tool and can help inform the continuing development of the data model.
The ‘Intelligent’ part
As a geoscientist, the whole process seems very intelligent to me, but the part of the process that I find particularly powerful is the ‘Machine Learning’ process where the model is continually learning and improving with each iteration. To show this visually, have a look at Figure 2.
Here, we have manually identified a small subset of documents (e.g. well production reports) which represent a good example of particular data types. With these templates identified, a batch of ~150,000 unclassified documents is loaded into the Petrosys Intelligent Search. The documents which the model deems to be similar to the original subset, are classified.
Figure 2: An example of the first iterative search through a dataset
However, as Figure 2 shows, there are still over 50% of the ~150,000 documents that are not classified and even those which are classified are only broken down into a few sub-categories.
Therefore, we need to update and refresh the model before loading the next batch of unclassified documents. These results are shown in Figure 3.
Figure 3: An example of the second iterative search through a dataset
There is now a wider mix of GIS and Seismic data classified and more than 50% of all documents have been categorised.
This iterative updating and improvement of the model continues until the model meets its goals and/or all the files are loaded. Figure 4 shows a further iteration in the model.
Figure 4: An example of the third iterative search through a dataset
Now, if I’m a geoscientist looking for files related to the ‘Parara-1’ well, I could go to my visualising tool and find the data I need to get my hands on. In the example below (see Figure 5) we have used the Petrosys Records Management module to find and access the data.
The simple process for the end technical user is:
Search for the name of the well (either in the title or within the document)
View/select which category of document you are interested in
Add 1 or more files to the download ‘cart’
Figure 5: The Petrosys Records Management (RM) module showing how an end user may find and access the required documents
Seems intelligent to me but I’d be very interested to hear what you think.

Bubble maps are a great way of applying a spatial context to production attributes linked to each well.
In Petrosys PRO you can create bubble maps using data from most of the EP well data stores that connect to PRO. Data from text is also supported, such as CSV and other column based files.
Bubble maps can be created not only from well header data but from formation and zone attributes too. Production rates could be used to scale the size of each bubble and, if you have defined more than one attribute the bubbles will be displayed as pie-charts, with the numeric value of each attribute being used to work out the proportion of the pie.
Aside from the typical production attributes, we can also map facies distributions across a specified zone or formation.
For example, the map below is showing the percentage of fluvial, channel, levee, and crevasse facies within the Top Ness formation. The facies % is computed from a discrete log in Petrel and, if it is assigned to a Petrel zone or formation, it can be mapped in Petrosys PRO.
You can also include a formula to compute appropriate derivatives. For example, you can complement water saturation (SW) with a formula such as (100-SW) for the hydrocarbon saturation. And lastly, bubble sizes can be scaled either on diameter or on the area and compare the sum of the mapped parameters against a user specified reference value and size. Area scaling is preferred for visual correctness.
Quick Tips on Creating a bubble map in Petrosys PRO
Create a bubble map showing facies distribution across your formation interval.
The facies % is computed as a discrete log in Petrel and, as long as it is assigned to a Petrel zone or formation, it can be mapped in Petrosys PRO.
If necessary, create a formula to compute derivatives or find missing values e.g.
Fluvial = 100 – (channel + levee + crevasse)
Choose whether to scale each bubble by an additional variable (e.g. porosity) and set up the scaling parameters to control the relative size of each bubble
Linear or logarithmic
Set reference values

We live in the age of digitization where everything and anything we want to look at or research can be accessed on a screen. Whole libraries of information are available in digital format, whether you want to check the weather, current events, or find a well log from decades ago, the information is just a few clicks away, ready to be viewed in full technicolor on your screen of choice.
The way in which we view and interact with maps of all types and across all sectors of life and industry has changed significantly too. As the self-proclaimed ‘Mapping Gurus’, here at Petrosys, we have a clear interest in how our customers work with maps, which has recently raised the question – why do we need printed maps when digital maps are so readily available?
Like most things this is not a clear-cut question – it really depends on the purpose of the map and the person viewing it. For the typical individual in daily life, a smartphone, Google Maps, and GPS means we can travel from A to B with relative ease, but what about the geologist and geoscientist working in oil and gas?
How the use of maps has changed in oil companies
Maps were formerly the stalwarts of the printed page, however with the continuing speedy growth of technology, viewing any kind of map on the digital screen opens up access to more than just 2D imagery.
In years gone by you could walk into the office of an oil company and see map tables piled high with paper copies of all types of maps. These maps were the stock in trade and companies had entire print rooms specifically designed for the purpose of printing out the varying sizes and editions of the maps as required. We’ll perhaps leave the intricacies of the correct method of folding maps for another discussion…but let’s just say it could be an art-form in itself.
As digital technology has progressed, however, the need to print all these maps has diminished. The dynamic nature of digitization allows digital maps to be edited and displayed within short timeframes and made immediately available for quick distribution. More importantly, the amount of information that can be contained within one map file can be enormous.
Take for instance the Petrosys PRO layered pdf. The information stored in the layers means that one map can have multiple uses within an organization. For example, geoscientists and engineers in a development team can discuss a new drilling target with no need for expensive proprietary software, or even an internet connection.
We also now no longer need to worry about data loss from printed maps – tools available in the Petrosys PRO spatial editor for example are able to convert images of maps into live surface and attribute maps. This facilitates the recovery of data from sources that may have preceded digital mapping or where the digital data management failed to keep up with document filing processes.
And yet, there is still a place for the printed map
The ease with which you can view, at a glance, the complete area of interest being worked on, printed at large scale right there on the office wall is undeniably a major draw. Being able to put a, correctly folded, map in a pocket without worrying about battery life is not to be taken for granted.
Produced annually by Petrosys sister company GPinfo, the Petroleum Permits Map of Australasia is a must have for many oil companies to this day. As the comments from just a few GPinfo customers prove, the printed map for some remains an invaluable tool for daily reference.
Copies of the 2020 GPinfo permit maps arrived this week and are already sprinkled around the office, including the boardroom and meeting rooms. The maps provide an excellent reference to petroleum permit and pipeline locations for Australia, New Zealand, and Papua New Guinea and are of a quality that Bridgeport is proud to support.
Barry Smith, Chief Technical Officer, Bridgeport Energy
The GPinfo Permits Map is a great product. It’s something I refer to almost on a daily basis and of course, it is an extremely useful reference in a whole range of forums, including Joint Venture and Board meetings.
Neil Gibbins, Managing Director, Vintage Energy
GPinfo maps are always in Carnarvon offices and used daily. COVID meant many took them home as a point of reference. In conjunction with the GPinfo GIS database and email alerts on permit changes, GPinfo and its maps are an integral part of daily life at Carnarvon over previous years and we expect to continue this for many years to come.
Stephen Molyneux, Exploration Manager, Carnarvon Petroleum
GPinfo Permit Maps have been part of Finder’s success since the company’s beginnings. They are on the walls of everyone’s office and continually remind us of the scale and potential of the Australian petroleum basins. Thanks, GPinfo.
