The EFA was initiated in 2010 as a memorial to the life and work of Dr. Ed Purdy, an acclaimed geologist who built a reputation as a carbonates specialist during a long career both with Exxon and as an independent consultant. The objectives of the EFA were to update a set of pioneering maps on Africa that Dr. Purdy authored and published in 1989. These were masterpieces of hand-crafted work, combining geology, tectonics, basin outlines, hydrocarbon discoveries and extensive use of annotation and color coding to highlight the known working plays across the continent. The EFA project entailed the digitization and enhancement of these maps as a multiplatform GIS, and was carried out on a pro-bono basis by a group of former friends and colleagues of Dr. Purdy, led by Peter Wigley.
The EFA project is now a multi-platform web-based GIS, and the team will be happy to demonstrate and discuss how it has evolved, plans for the future, and donations to Africa-based charities and academic institutions from the proceeds of the project.
Badly need to load and reinterpret a key seismic line, but all you have are some color powerpoint slides from a long-lost workstation project? Here’s a solution. Version 25 of the Lynx Seismic Scanning & Vectorizing application (SSV), for robust and rapid conversion of analog trace data to SEG-Y, now supports the vectorizing of seismic data from gradational color and greyscale displays. See how it works here…
The iXplor web viewers provide intuitive and secure web-based visualization for digital 2D seismic lines and 3D seismic surveys, digital wireline logs and high-resolution raster images of seismic sections and well logs. The viewers work in all modern browsers on desktop and mobile platforms, with no browser plugins required.
The iXplor Viewers provide a secure mechanism for viewing of confidential, sensitive and valuable digital data by preventing direct access to the digital source data – the end user will only ever see a set of small image tiles which are reassembled in the browser for viewing. As an additional measure, a repeating watermark for all imagery can also be added for all displays.
iSeisview works with industry-standard SEG-Y for 2D lines and 3D volumes
End-user can interactively choose display colors, vertical and horizontal scales and amplitude scales
2D profile viewer shows a standard two-way time display of the seismic trace data

iRasview works with images in PDF, TIFF, JPEG or PNG format; multi-page images can be automatically concatenated
Instant display of high-resolution images, with no scrolling lag
iRasview 1/5 – high resolution scanned composite log image
iRasview 2/5 – multi-page images (eg well composite logs in PDF format) are concatenated
iRasview 3/5 – high resolution image of a scanned seismic section profile
iRasview 4/5 – zoom into high resolution color composite log image
iRasview 5/5 – watermarked display
iXplor Viewer Technology
The iXplor Web Viewers can be deployed on a Tomcat Java application server running on Windows Server.
All the viewers require server-side configuration by an administrator to define the set (or sets) of digital source files which are available for viewing Each dataset includes a set of files on disk and an associated metadata table (in either a PostgreSQL, Microsoft SQL Server or Oracle database, or as a shapefile or CSV files) including geospatial information (if available) for determining locations and intersections. The datasets may be updated dynamically via the admin GUI or REST interface.
The iXplor web viewers are available either as an integrated part of the Lynx iXplor CMS platform for national data archives, as server-side components for an existing E&P web mapping platform, or as part of a hosted Virtual Data Room from Lynx.
If you would like to know more about the Lynx iXplor Web Viewers, please ask us for more details.
The VDR for Trinidad and Tobago’s 2020/21 Deep Water Competitive Bid Round is now offering the opportunity to download four of the 3D surveys for free. Approx. 5,500 sq kms of data acquired in 1998. Access the VDR via https://ttdeepwaterbid2020.com.
The annual HGS-PESGB Africa conference is this year being held online with sessions running on consecutive Thursdays throughout October 2020.
Lynx were pleased to submit a poster presentation for the second session held on 8th October, entitled ‘“EFA Online” – A GIS Portal for Africa Explorationists‘.
This 5-minute presentation provides a demonstration of the Exploration Fabric of Africa (EFA) project, an enormously successful collaborative effort to gather and publish continent-wide maps charting broad knowledge of African exploration results set against a framework of regional geology, tectonics and gravity-magnetics data. Many of these map layers have been recently updated and are now available for viewing via an interactive online web map.
A recorded video of the presentation can be viewed here.
Access to EFA Online is complimentary for all 2020 Africa attendees – please apply here for access.
Lynx iSeisview now has a new ‘cube’ viewer for 3D seismic surveys. This new viewer is enabled by default for 3D surveys, and provides an interactive 3D cube perspective view of the survey, allowing zoom and rotation to view inline and crossline profiles from any angle, with a choice of display styles and scales.
The new cube viewer works in all modern browsers (Google Chrome, Mozilla Firefox, Apple Safari and Microsoft Edge) on desktop and mobile devices, and even (with a few small limitations) in Microsoft Internet Explorer. Use your mouse or touch gestures to rotate, pan and zoom the view of the 3D survey.
The 3D viewer display can be switched dynamically between the new ‘cube’ perspective view and the original ‘flat’ inline or crossline profile viewer. The mouse position in the seismic viewer is updated dynamically on the basemap to reflect current CDP position on both profiles.
Contact us about licensing options for iSeisview, or for more information on the Lynx iXplor Content Management System or Virtual Data Rooms.
Ukraine oil and gas licence bid rounds are coming thick and fast! Hard on the heels of the 6th Dec 2018 announcement of an auction for 10 licences, Ukraine’s State Geological Service announced its intention to put 10 Production Sharing Agreements (PSAs) under the hammer, with the auction date to be announced in mid-February to March. Soon afterwards, on February 2nd 2019, the acting head of the SGS Oleh Kyryluk declared in London that a second tranche of 7 blocks was to be put up for grabs in an online auction of licences, to be held around 2nd May.
Of the offers in Licence rounds 1 and 2, three are in the Carpathian region of West Ukraine, one in the Odessa area bordering Romania and the remaining thirteen in the prolific Dnieper Donetsk depression. Although the PSA round has yet to begin, the PSA block polygons have been published and cover large tracts in the DDD, with more modest areas in West Ukraine.
Lynx has a large and growing library of exploration data from Ukraine, covering the areas of most of these blocks. Our Dnieper Donetsk and Carpathian GIS products contain a wealth of data on fields, reservoirs, geology, wells and prospects and have recently been updated to include data from the latest discoveries and materials released by the SGS since the “opening up” of Ukraine’s subsurface data by an act of parliament last year. For specific areas or requirements, Lynx can build bespoke GIS based projects using data from our own extensive library, including georeferenced and digitized map layers, document translation from Russian and Ukrainian, seismic processing and interpretation together with researching data from the SGS archives.
