Near-surface structure of the Carpathian Foredeep Marginal Zone in the Roztocze Hills area
(Springer, 2018-04)
Shallow seismic survey was made along 1280 m profile in the marginal zone of the Carpathian Foredeep. Measurements
performed with standalone wireless stations and especially designed accelerated weight drop system resulted ...
Characterization of drilling-related noise and curvelet-based evaluation of seismic-interferometric reflections for imaging of iron-bearing formations in Pilbara,Western Australia
(2021)
Here we analyse ambient noise (AN) data generated during drilling of exploration boreholes
and recorded using a dense array deployed over one of the numerous shallow iron-ore mineralisation
targets in the Pilbara region ...
Structure of a diffuse suture between Fennoscandia and Sarmatia in SE Poland based on interpretation of regional reflection seismic profiles supported by unsupervised clustering
(2021-03-31)
The Paleoproterozoic suture between Sarmatia and Fennoscandia (SFS), two major components of the
East European Craton, extends SW-ward from Russia through Belarus to SE Poland. The exact
character of this suture remains ...
Anisotropy Estimation of Lower Paleozoic Shales from Northern Poland using Microseismic Data
(Institute of Geophysics, Polish Academy of Sciences, 2021)
Downhole microseismic monitoring is a widely used tool for the assessment of hydraulic
fracturing job effectiveness. During the process of fluid injection into the reservoir, new fractures develop due to the induced ...
Variations of permafrost under freezing and thawing conditions in the coastal catchment Fuglebekken (Hornsund, Spitsbergen, Svalbard)
(2022)
Two seismic field surveys were organized in the Fuglebekken coastal catchment of Hornsund, Spitsbergen, Svalbard, to map frozen and unfrozen ground and assess the spatial and temporal state of the permafrost. Surveys were ...
Dispersive seismic waves in a coal seam around the roadway in the presence of excavation damaged zone
(Elsevier, 2021)
Excavation damaged zone (EDZ) is a fractured rock mass in the vicinity of the roadway. Knowing its elastic properties, such as seismic velocity, is crucial for the safety of underground mining. However, the seismic wavefield's ...
Gas-Escape features along the Trzebiatów fault offshore Poland: Evidence for a leaking petroleum system
(Elsevier, 2023-08-08)
New 2D high-resolution seismic and hydro-acoustic data demonstrate the presence of methane in the shallow sediments and its origin in the Pomeranian Bight, south of the Baltic Sea area. Various shallow gas features including ...
Seismic Data Processing Report BALTEC
(Institute of Geophysics, Polish Academy of Sciences, 2020-12)
The BalTec 2D seismic survey was recorded in 2016 by Federal Institute for Geosciences and Natural Resources (BGR) during the German R/V Maria S. Merian cruise MSM52 in the Baltic Sea. Around 3.500 km of multi-channel ...
Full waveform inversion and Lagrange multipliers
(Oxford University Press on behalf of The Royal Astronomical Society, 2024-04-19)
Full-waveform inversion (FWI) is an effective method for imaging subsurface properties using sparsely recorded data. It involves solving a wave propagation problem to estimate model parameters that accurately reproduce the ...
Robust elastic full-waveform inversion using an alternating direction method of multipliers with reconstructed wavefields
(Society of Exploration Geophysicists, 2024-05)
Elastic full-waveform inversion (EFWI) is a process used to estimate subsurface properties by fitting seismic data while satisfying wave propagation physics. The problem is formulated as a least-squares data fitting ...
