London - 21st March 2016 - Ikon Science researchers have created a significant new technology within the RokDoc® GeoPrediction platform which optimises seismic well-ties in both broadband and conventional seismic surveys allowing for improved geophysical and geological reservoir characterisation. The new module includes wavelet estimation and editing techniques that greatly improve the seismic to well calibration process. The four research sponsor companies acquired the new functionality in early 2016.
The new ‘Advanced WellTie’ module in RokDoc, which has been commercially released today, has been written to ensure that those companies who have acquired superior ‘broadband’ seismic data are able to properly benefit from the additional low and high frequency information in their data which existing wavelet estimation techniques fail to adequately recover. The very low frequencies (2 - 8 Hz) in Broadband seismic which can deliver 2-3 additional octaves of information require appropriately long well log data, which is often unavailable, to enable calibration for rock property inversion and reservoir characterisation. Ikon Science has developed the new methods and functionalities to specifically address this, amongst other issues thus allowing a far greater confidence in the assessment and utilisation of the low frequency content in broadband acquired / processed seismic data.
The Ikon Science principal researchers included Dr Ehsan Naeini, senior research advisor, in collaboration with Professor Roy White of Birkbeck, University of London and Dr James Gunning of CSIRO. The new well-tie module in RokDoc® contains sophisticated yet easy to use methods for wavelet estimation and analysis including new parametric constant phase, multi-tapering in the frequency domain and time domain Bayesian approaches. These techniques have different mathematical foundations thus allowing interpreters to explore a variety of different approaches in order to assess the uncertainty in their seismic data and its impact on reservoir characterisation.
Ikon Science CEO Martyn Millwood Hargrave commented: “These ingenious new methods enable additional high value information to be extracted from existing seismic data with much greater accuracy and confidence, providing more value for less cost. Applied in combination with our revolutionary RokDoc® 3D and JI-FI software, our clients will be armed with the most effective 21st century methods for prediction of rock properties and hydrocarbon reserves available”.
