An 'Inverse CCS Site' in NW Hungary – Geology and Modeling

Proceedings, 2012
The research of natural analogues for future CCS projects is a dynamically growing sector of geoengineering. In our work this newly discovered aspect of a CO2 field is presented. In NW Hungary there is a field utilized for more than 60 years. Thus there is a large amount of data from hydrocarbon exploration, gas measurements, seismic sections, well ...

Depth-Domain Pre-Stack 4D Seismic Inversion in Complex Geology

81st EAGE Conference and Exhibition 2019, 2019
Present industry 4D workflows normally use the co-processing and imaging of baseline and monitor surveys with the same depth-interval velocity model. Standard practice is to re-align the migrated offset or angle stacks vintages with dynamic 1-D Warping and extract amplitude differences for 4D interpretation.

Geology-guided Quantification of Production-Forecast Uncertainty in Dynamic Model Inversion

SPE Annual Technical Conference and Exhibition, 2011
Abstract The presence of a large number of geologic uncertainties and limited well data typically increase the challenges associated with hydrocarbon recovery forecasting. Although recent advances in geologic modeling enable the automation of the model generation process by means of next-generation geostatistical tools, the computation ...

Structurally tailored 3D anisotropic controlled-source electromagnetic resistivity inversion with cross-gradient criterion and simultaneous model calibration

Geophysics, 2019
Geologic interpretation of 3D anisotropic resistivity models from conventional marine controlled-source electromagnetic (CSEM) data inversion faces difficulties in low-resistivity contrast sediments and structurally complex environments that typify the ...

Amplitude Inversion of Depth-imaged Seismic Data from Areas with Complex Geology

Proceedings, 2013
Conventional amplitude inversion assumes that the input migrated image has preserved relative amplitude information and is free from the effects of illumination. Under this assumption, stretching a depth migrated image back to time and applying inversion based on 1D convolutional modeling can produce reasonable results. However, illumination effects in

Inverse Methods to Combine Geology, Geostatistics and Multiphysic Data

Proceedings, 2012
Inverse methods are used to infer model parameters from observed data that are related via random or deterministic functions. Their application to Earth Sciences has expanded more recently to encompass the problem of data and information integration considering the combination of multiple geophysical data surveys, information of multiple properties ...

Progress in Defining Deeper Realistic Geology Using AEM 2.5D Joint Inversion

78th EAGE Conference and Exhibition 2016, 2016
Including interpretations from airborne geophysical surveys to build geological models continues to improve outcomes for deriving more realistic geological representations. It is now highly practical for AEM data to be both forward modelled and inverted using 2.5D numerical approximations.

A Forward Glimpse Into Inverse Problems Through a Geology Example

PRIMUS, 2012
This paper describes a forward approach to an inverse problem related to detecting the nature of geological substrata which makes use of optimization techniques in a multivariable calculus setting. The true nature of the related inverse problem is highlighted.
