Fugro Data Management has released version 6.0 of its Trango Seismic
data management software, with tools to track the history of data, and
with integration with OpenSpirit
Fugro Data Management, the data management division of geosciences and survey company Fugro, has launched a new version of its Trango Seismic 6.0 tool for upstream seismic data management, which allows users to track the parentage or hierarchy of data files (“lineage”) and has integration with OpenSpirit, so it can be used to manage data which is only stored in interpretation packages.
The company is planning similar upgrades in the fourth quarter of 2010 for its software package for well data, “Trango Well Manager”, and its software for geological reports.
The lineage function provides the ability to see all the iterations of what’s happened to a piece of data, says Leonard Hendricks, VP for Trango at Fugro Data Solutions (Canada).
“For example, if you’ve got the original field tapes from offshore seismic acquisitions shoots, then you can see someone did some preliminary work to create a prestack set of files. From there, there was work to create a stack file.”
“Then maybe inversion was performed on it, or another post stack process was built on it. Or perhaps you have gravity or magnetic field data. There could be 2 or 3 different sets of processes.”
The software will record what work was done, when it was done and whhere it is located, he says.
The system is useful if later work shows an error in the process and you want to retrace your steps. If you redo an earlier step, you want to know what files were generated out of the faulty data and make sure they are replaced.
Or maybe one aspect of the data will become more important in the future (for example if it is about a region where major finds have been made or seismic can no longer be shot) and you want to find the ‘parent’ data and work that data or project again.
OpenSpirit
The interface with OpenSpirit enables data to be managed within Trango which are stored within people’s interpretation software. It doesn’t matter which interpretation software they are using, as long as it is compatible with OpenSpirit.
OpenSpirit provides a range of tools to enable different geological and geophysical software packages to interoperate.
Many independent oil companies sometimes only have data in interpretation environments, by using Trango software with the Open Spirit interface they can access all of this data in other systems, and can copy available meta-data, trace outlines and data location into Trango.
Trango indexes all of the data (eg by project or survey name) through OpenSpirit to the interpretation files. This means that everybody in the company knows which interpretation projects exist around the company, what datasets have been loaded into them, and who is working on them.
The company is developing the same capability for its Well Manager tool to manage well data, where there will be a ‘lineage system’ – you can retrieve original logs, and then the interpreted logs after various pieces of processing work have been done.
Via integration with OpenSpirit, you can pull out metadata for the same wells from other software packages, or other software packages can pull data out from Trango via OpenSpirit.
Driving take-up
There are many factors driving an increased interest in data management systems for seismic data.
There is a growth of interest in 4D data (where people want to see how seismic data has changed over time). “A lot of the old files are becoming more important,” he says.
Some companies developed data management systems in-house, and are finding that it might be a good time to bring in a commercial system, he says. Companies sometimes want a more formal data management tool as they get bigger that is commercially maintained with functionality input from many different E&P companies.
Sometimes companies only use public seismic data, and they think they don’t need to bother having data management systems of their own, because they can always get the data from the public source whenever they need it. But then they realise that they are not tracking the work they are doing with the data and what value they are adding to it, and look for a tool like Trango, he says.
Mr Hendricks says that many companies consider a data management tool after they’ve been through an acquisition, for example as a way of organising the data of a company which has been acquired.
Many companies don’t even have a master list of their seismic assets, he says. “We often find customers, the first output they’re looking for, is a map of all the seismic assets they have.”
Everybody has maps, of course, but not complete ones, which show everything you need to understand your company’s seismic data – such as whether the data is licensed, proprietary, or the company only has rights to it for a period of time, or perhaps has exclusive rights for a period of time. “This information is not important in an interpretation package,and therefore not captured in that environment” he says.
But this information can be very useful for many people in the company – particularly if it gives the company a chance to sell licenses to, or trade data which they own but are not currently interested in, with data someone else has which would otherwise cost them a lot of money.
