Broad-band Well Tie & Ji-Fi Lunch & Learn 

The Ikon team looks forward to welcoming you for a delicious buffet lunch, followed by an afternoon of seminal talks from 2 of our experts - Dr Ehsan Naeini and Drs Michel Kemper. 

Read on for more details about both talks, the speakers and the agenda.

Talk 1: Broad-Band Well Tie
By extending the low-frequency content, broad-band seismic data lessens the dependence of seismic inversion on a background model. Despite that, the merging of the inverted seismic with a very low frequency background model poses a new problem: the duration of a well-log synthetic seismogram is often seriously inadequate for defining the sharp spectral decay to zero frequency. To address this issue, a practical approach based on spectral analysis is proposed to determine the low-frequency spectral decay of the seismic well tie wavelet. Furthermore the impact on seismic inversion is demonstrated.

Talk 2: Introducing Ji-Fi - A New State-of-the-art Seismic Inversion System
Seismic inversion is a mixed discrete/continuous problem, which to date is solved continuously only in the great majority of algorithms. Ji-Fi uses the correct physics, i.e. inverts jointly for Facies (discrete quantities) and for Impedances-per-Facies (continuous quantities). The result is a hugely significant increase in inversion quality in our opinion.

Ji-Fi is actually much easier to run than Simultaneous Inversion, as you are not at the mercy of endless LFBM building! Ji-Fi is better and easier; the price you pay is in increased run-times (but reduced set-up and QC times re-pay that handsomely).

Ji-Fi is a new inversion technology, and we are rapidly applying it to various datasets, some of which we will show in the talk.  We anticipate a big uplift in Unconventional plays, as Facies (ductile vs. brittle for Shale gas, tight vs. higher-porosity for Tight Oil, cold vs. hot for Heavy Oil) can be inverted for more accurately than with conventional techniques such as Simultaneous Inversion followed by Bayesian Classification.

Furthermore, a more reliable, Ji-Fi generated Facies image may have a positive impact on a number of subsurface workflows, such a pressure prediction, de-risking of deep offshore prospects, more accurate geological modelling in terms of flow units etc.
