| An example of absolute impedance output from SA Inversion through InSeis. |
Equipoise Software are a London based software company which are a sister company of the very well respected ERC Equipoise, and are very well known for the Petrel / IHS Kingdom plugin Velit, of which boasts a number of features to vastly decrease uncertainty.
Velit is industry standard software, and reduced uncertainty, more efficient workflows and of course Velit’s advanced library of depth conversion techniques have cemented the plugin’s relevance to modern day geophysics as well as petrophysics.
Off the back of the advances made with Velit, Equipoise Software have another plugin which is making headway in the field of seismic inversion. InSeis is a plugin which is intended for usage within Petrel as well as IHS Kingdom, and is an excellent solution for seismic inversion. In today’s world, seismic inversion is a far cry from mostly optional exploration tool which has took a back seat compared to depth conversion. Nowadays, seismic inversion is useful for obtaining far more accurate interpretations and better estimations of reservoir properties.
InSeis is a neat little tool which covers very many forms of seismic inversion, most notably Coloured Inversion and Simulated Annealing Inversion, for every situation. Coloured Inversion on InSeis is rather quick but the results are still comprehensive – easily comparable to far more time and labour consuming sparse spike methods of seismic inversion. Bed resolution is enhanced, as well as minor faulting, fracture zones and discontinuities are better highlighted- which for some projects can be very helpful, offering far more of an insight to the geologist.
Simulated Annealing is made simple in InSeis thanks to the plugin’s model driven approach, which entirely and automatically removes the seismic wavelet, as well as providing an output of high resolution relative impedance, as well as absolute. Since InSeis’ Simulated Annealing is easy to parameterise and run, it completely avoids the problem of needing to be trapped at local minima by using global optimisation.
Inseis is an absolutely revolutionary project, which provides an excellent toolkit for geologists and geophysicists which place value in getting as much of the picture as possible.
