... We introduce a new idea to build a generalized training set for supervised machine learning (ML) methods aiming at gravity modelling. We build synthetic models reproducing only faults, which could be seen as the building blocks of each gravimetric anomaly. Here, we discuss preliminary results...

... Effective subsurface CO 2 storage necessitates monitoring and accounting for injected CO 2 . Gravity methods are an enticing appliance for CO 2 monitoring since the change in density observed by the gravity method is directly related to fluid saturation. In particular, three-axis borehole...

The magnetic results are felt to be largely mapping changes in lithology whereas the ZTEM Ground gravity (Anonymous, 2008) was carried out over the appears to be mapping major structures. The magnetic model deposit and surrounding area. These results...

... Gravity maps for both Algeria and Australia, together with the SRTM terrain models are the starting point. Both countries have considerable Quaternary sand cover, making basement mapping more difficult. Geoscience Australia recently released isostatically corrected gravity data grids...

... ABSTRACT Deep learning has achieved a great success in various fields in recent years. As a powerful tool, deep learning is used to interpolate the gravity and magnetic data with block lack of data in this paper. We firstly designed a deep convolution neural network (CNN), and mask dataset...

... ABSTRACT A recent BHP Petroleum exploration program investigated the frontier Northern Beagle Sub-basin, which is part of the greater Northern Carnarvon Basin and is located approximately 300 km offshore in NW Australia. Onboard gravity and magnetic data were acquired as part of the 22130 km...

... ABSTRACT When presented with a gravity data set for any area, two numbers are typically of interest: the resolution and the accuracy. The resolution is the spatial size of the smallest features visible in the data; the accuracy quantifies the reliability of the features in the data. It is well...

... ABSTRACT Carbonate build-up and pinnacles exploration in offshore northwest Borneo has typically relied almost entirely on the interpretation of 2D and 3D seismic data of different vintages. This paper presents the results of integrating high quality gravity acquisition over the region...

... ABSTRACT Gravity signatures at the places near a basin can be used as a lead in estimating the size and depth of deep seated geological features. Generally, gravity values tend to decrease when approaching towards a basin; however, if the basin has deep seated high density materials...

... ABSTRACT The joint inversion for gravity and seismic data based on the matching constraint is presented. We directly introduce the gravity and seismic matching term in the gravity inversion process, which represents seismic data with physical parameters. This can avoid the determination...
