What is Searchable Coverage?
First off, we have a continually growing database of approximately 380,000 wells of generally surface to basement searchable coverage. Creating this unique database was a very complex and time-consuming task. Completion of just the initial phase took an array of 25 LINUX computers running full time for over three years. An additional year was required to perform the secondary and tertiary conversion functions. The conversion functions use proprietary software programs developed and owned by Unitech. As of January, 2008, the databases are approximately 2 terabytes in size.
While suppliers of digital well logs will brag about their numbers of well log curves, and how big their digital well log databases are, they are quick to change the subject when asked about searchable coverage. This is because, while their well log curve counts may be high, they cannot supply full suites of well log curves over very many wells. For example, one supplier claims to have over 175,000 “digital” wells. Interestingly, their definition of “digital” is a well with at least one digital curve.
They may have 175,000 wells with a digital sonic curve, but only 40,000 wells with all of Sonic, SP, Resistivity, Density/Neutron porosity, and Gamma (full suite). With their database, if you’re searching for anything other than sonic porosity, you would generally be out of luck – that’s the part they don’t tell you.
Other suppliers claim full suite coverage but the problem is that they have only 90,000 of the 300,000+ existing wells so their database has too many “holes” in it to be of much use as a searchable database.
LeadScan uses the original well log images and extracts the available curves from each log. This means that LeadScan has both far greater well coverage, and far more searchable coverage. Nobody else even comes close.
How the Technology Works
The intellectual input of more than 20 geoscientists (engineers, geologists, geophysicists, and petrophysicists) is incorporated in the proprietary analysis algorithms that are the “brains” of the LeadScan software.
In the world of oil&gas, the LeadScan system addresses the fundamental problem of low levels of searchable well log data coverage. While there are millions of wells logs in existence (wells logs are the backbone of the geological discipline), only a fraction of these logs are in a form that allows their numeric values to be read and analyzed by computer.
This means that geologists must process these logs manually and this significantly impedes the entire exploration process. The geoscientific disciplines of engineering, geophysics, and petrophysics are all highly computerized but the geology discipline is still largely a manual process and the lack of searchable data is largely the reason why.
Management believes that LeadScan is the most advanced tool of its type in this area.
Unitech owns 100% of the LeadScan software and database - there are no fees or royalties payable to anyone. Unitech does not license LeadScan to third parties.
