2D Land Joint Inversion of Seismic, Magnetotelluric and Gravity for Pre-Stack Depth Migration Imaging, Nechako Basin, BC

Lead Researcher(s):  M. Sfolciaghi

Project ID:  2009-043

Key Research Organization(s):  WesternGeco - Multi-measurement Depth Inversion Centre (MDIC)

Project Location:  Nechako Basin

Strategic Focus Area:  Energy-Oil and Gas

Summary



This project describes the analysis and processing applied to the Nechako Basin 2-D data set. The processing is aimed at better defining the regional structure of the Nechako basin, which is largely covered by volcanic rock of variable thickness. The processing is based on a joint inversion technique using different geophysical domain such as seismic, gravity and magnetotellurics in order to obtain a better velocity model.

      Geoscience BC Report 2010-16 describes the analysis and processing applied to the Nechako Basin 2-D data set.

      The processing is aimed at better defining the regional structure of the Nechako basin, which is largely covered by volcanic rock of variable thickness. The processing is based on a joint inversion technique using different geophysical domain such as seismic, gravity and magnetotellurics in order to obtain a better velocity model.

      This report contains a technical report describing the analysis and processing applied to the Nechako Basin 2-D data set, as well as nine Pre-Stack Depth Migration (PSDM) datasets in sgy format (filtered PSDM stack, PSDM converted to time stack and PSDM final velocity field files for seismic lines 05, 10, and 15.

      The work was performed by WesternGeco MDIC for Geoscience BC, in WesternGeco’s processing centre in Milan, Italy, from July 2010 to September 2010
