InSeis is a Seismic Inversion Software Plug-In

Coming to Petrel Q1 2016 & available now as part of Kingdom 2015 

Overview

InSeis consists of two different seismic inversions techniques, Colored Inversion and Simulated Annealing Inversion, both of which aim to turn the seismic signal into an acoustic impedance layer model.

Colored Inversion Overview

Coloured Inversion is a fast and lightweight tool that enables interpreters to quickly generate a relative acoustic impedance data type from the reflection seismic data for the purpose of more accurate, more confident seismic interpretation.

Simulate Annealing Inversion Overview

Simulated Annealing Inversion is a more complex procedure resulting in absolute acoustic impedance, which can be calibrated to well log data for generating petrophysical volumes.

Features

Supports single and multi-well analysis Automatic seismic to well phase correction Quality control at each stage of inversion operation Sonic log to time-depth curve and check shot calibration Highly customizable, user friendly interface Simple data requirements Fully integrated with Petrel/Kingdom

 Benefits

The inversion enhances your seismic data making it easier to interpret, increasing interpretation  productivity and accuracy Fast and robust method of generating a seismic inversion data type ideally suited for use by all interpreters Matches seismic data to well log data to produce cleaner data with less noise and less signal instability Neither wavelet nor low frequency macro-model is required Simple for the interpreter to set up and use Ideal ‘quick look’ inversion tool for use prior to more detailed inversion studies

InSeis is branded as Kingdom Seismic Inversion within the IHS Kingdom software

Inversion Procedure

Inversion as a general procedure attempts to explain the results of a set of observations in terms of the parameters of a model for the system from which the observations have been made. The aim of seismic inversion is specifically to transform the conventional seismic reflection responses into a layered model representation that distinguishes different formations.

The model parameters to be determined are the formation properties. Seismic inversion thus aims to replace boundary responses by layer properties. When the seismic reflection signals to be inverted are conventional stack traces – ideally near offset responses – the formation property of the layered model to be estimated is acoustic (P-wave) impedance. Acoustic impedance is the product of rock velocity and density – key parameters that relate to porosity, permeability and other reservoir properties.
