Geophysical inversion using petrophysical constraints
Petrophysical information is sometimes available from well logs, laboratory measurements, etc. It has been shown that incorporation of such information into geophysical inversions can greatly improve the recovered models. However, when the known petrophysical information is not applicable throughout the entire region, the application of petrophysical constraints to geophysical inversions could ...
متن کاملFast-track ‘coloured’ inversion
Inversion of seismic data to Acoustic Impedance is usually seen as a specialist activity, so despite the publicised benefits, inverted data are only used in a minority of cases. To help overcome this obstacle we aimed to develop a new algorithm which would not necessarily be best in class, but would be quick and easy to use and increase the use of inversion products within BPA. This new techniq...
متن کاملTechniques for generic probabilistic inversion
Simple algorithms for probabilistic inversion are proposed, based on iterative sample re-weighting. One of these, iterative proportional fitting (IP F), dates from the 1930's and has been studied extensively with regard to contingency tables. A new algorithm is shown to converge even when IP F is infeasible.
متن کاملJoint inversion of seismic traveltimes and gravity data using petrophysical constraints with application to lithology differentiation
Joint inversion of different geophysical data sets has recently received considerable attention. Different geophysical methods are sensitive to different physical properties and their variations on different scales, and joint inversion provides a way to combine these complementary information contained in each data set by integrating all the geophysical data into a single inversion scheme. The ...
