Motivation Two major civil infrastructure projects in the United Kingdom required accurate and precise mapping of subsurface porosity and permeability to ensure that underlying sediment formations were suitable for the intended construction. ...
ImpulseRadar Chief Technical Officer Bernth Johansson says, combined with the synchronisation of accurate positional data, each survey line, or ‘swath’, can be precisely aligned to adjacent swaths, optimising the data gathering process for efficient subsurface mapping. “Those new to 3D GPR systems – or arrays, as they’re commonly ...
Key words: Groundwater, passive seismic, Horizontal to Vertical Spectral Ratio (HVSR), paleochannels Introduction Geophysical survey methods are widely used for groundwater resource mapping, and mapping subsurface hydrogeology to assist with determining the best location of water bores and help to provide preliminary volume estimations. ...
A reflection seismic survey was performed in the city of Lausanne (CH) to map geological layers relevant to geothermal energy production. By using a wireless seismic system and a powerful seismic vibrator source we were able to high quality results despite the presence of elevated urban noise levels. The new subsurface maps allow the ...

Passive Seismic Tomography Project Project Area: approximately 1000km2 (4700km2 with the peripheral stations) Seismic Network: 80 stations Recording Period: 5 months The scope of this project was the successful completion of a full Passive Seismic Tomography survey in Asmat – Papua, Indonesia, for subsurface mapping purposes and detection of possible ...
While employed with Conoco, Inc. analyzed and correlated well-log data in order to produce geologic structural maps of subsurface horizons in Louisiana and Oklahoma, for the purpose of oil and gas prospect generation. Analyzed and correlated well-log data in order to map the top of a highly permeable subsurface formation that ...
After multiple unobtrusive readings taken by a Willowstick surveyor, the data is applied to mathematical algorithms and used to create maps and three-dimensional models of the subsurface groundwater paths. ...
In 2006 the company brought in Willowstick, a Utah-based company whose AquaTrack Technology creates accurate, contoured maps of subsurface water paths. Willowstick was charged with helping Chevron engineers discover what was occurring beneath the ground. ...
“You have this spot in time and space you’re looking at and trying to gauge the characteristics of the subsurface. That’s a difficult thing to do.” URS needed a way to positively identify the subsurface characteristics. ...
The purpose of the project was to demonstrate how the AquaTrack technology can be applied to subsurface oil reservoirs which are subjected to water and/or steam flooding and to map the subsurface water paths. ...
Passive Seismic Tomography Project Phase II Project Area: approximately 2000km2 Seismic Network: 76 stations Recording Period: 9 months Number of Seismic Events located/used: 276/263 The scope of this project, which followed a successful Phase I Passive Seismic Tomography survey in the same area, was to provide accurate and reliable 3D P-wave velocity and Vp/Vs models, adequate for ...
Passive Seismic Tomography Project Phase II Project Area: approximately 400km2 Seismic Network: 70 stations Recording Period: 11 months Number of Seismic Events located/used: 1200/1100 The scope of this project, which followed a successful Phase I Passive Seismic Tomography survey, was to provide accurate and reliable 3D P-wave velocity and Vp/Vs models, adequate for ...
A conceptual site model (CSM) was developed based on differential water level responses as well as on subsurface soil sampling,published surface geologic mapping and hydrogeologic cross sections of the Orange County groundwater basin. ...
Passive Seismic Tomography Project Phase I Project Area: approximately 900km2 Seismic Network: 50 stations Recording Period: 11 months Number of Seismic Events located/used: 2500/1860 The scope of this project was to provide coarse, but reliable 3D P-wave velocity and Vp/Vs models, adequate for a reconnaissance stage mapping of an area of about 900km2 around the Delvina Gas ...
