The focus of the detailed underground prospecting, mapping and sampling program was to further evaluate the subsurface geology and identify areas for future drilling, and serve as an important resource for the creation of a 3D geological model of the nickel-copper-cobalt rich property.
Seequent is in the development of visual data science software for understanding subsurface geology, with customers in over 90 countries.
A hydrogeophysical survey using Vertical Electrical Sounding (VES) is adopted to outline subsurface geology and to produce a subsurface model based on the resistivity contrast of layered rocks for evaluating the groundwater accessibility.
For instance, since seismic waves travel at different speeds through different minerals, analyzing the changes in the waves can allow mapping subsurface geology. While other methods are already used to do this sort of seismic tomography, they rely on an artificial source to create the waves, while this natural method could be far more efficient.
Hundreds of thousands of wells have been drilled in the region: there are few places on the planet where the subsurface geology has been better explored and understood.
The film combines real footage with 3D animation, allowing viewers to visualise the complex subsurface geology of Qatar's largest offshore oilfield, which is hidden some 2,500-3,250 feet below the seabed.
A NEOS presentation about the Lebanon project notes that Syria has many onshore discoveries and that there could be similarities between the two countries' subsurface geology. Chris Friedemann, NEOS' chief commercial officer and executive vice president, explains in a presentation of the project that "additional questions [about Lebanon's onshore] of fundamental importance -- including the location of faults, burial and thermal histories and basic basin architecture and morphology -- all remain unanswered.
He says spent nuclear fuel should be stored in a mountain with a crack-free solid igneous rock core located in a remote, seismically-stable area where there has been extensive mining so that the subsurface geology is well known.
Lightning-strike location and attribute map patterns are impacted by zones of resistivity and conductivity, and especially when integrated with other geological and geophysical data can be used to make scientifically based predictions (measured and repeatable) about subsurface geology and geologic features like faults.
Ololade et al., [11], in an integrated survey, employed electrical resistivity imaging to reveal the subsurface geology of an agricultural region where recent spirited efforts to cultivate cocoa showed poor results after initial bright prospects.
For this to happen, we need to enhance our imaging of the subsurface geology.
