Geophysics Analysis & Interpretation

Cut costs with good geophysics

Isolate subtle faults and zones of tectonic stress

 at varying depths in the basement and overlaying sedimentary, including intrabasin faults and buried volcanic rocks, intrusions, lithology contacts, etc.


Map the crystalline basement topography

Map the depth to basement in 3D from data points collected every 3 to 5 meters laterally along flight lines. This innovative approach provides vital information about the basement structure, the location of faults in the basement and their propagation. Basement structures, fault blocks and grabens, steep, brittle, and often seismically sub-resolution faults become evident and the basement fabric is revealed. 



The company consists of a staff of professional and recognized experts:

  • geophysicists
  • stuctural geologists
  • geochemistry - analysis - geologists
  • Seismic integrated with magnetic, gravity and electromagnetic imaging and interpretation
  • mathematicians
  • and computer imaging specialists

Isolate FAULTS, LITHOLOGY CONTACTS and STRUCTURES at Varying Depths – this innovative method is particularly useful for mapping subtle faults, shear zones, porphyries, as well as VMS, conduits, kimberlite signatures, etc and produce depth slices of the identified structures.


Map the crystalline basement topography and depth to basement in 3D from data points collected every 3 to 5 meters laterally – particularly useful in uranium exploration as well as in other exploration projects to better understand the faults propagation to sedimentary layers.


 Map CONDUCTORS, using a new type of airborne survey collecting large amount of data points near surface and deeper, including through very conductive sections. This is the most powerful airborne EM system currently in operation. The TerraNotes advanced mapping of EM produces depth slices of the identified conductors with clear delineation of axe and edges, as wells splays and describes their interaction.


Alteration Zones -- Detailed mapping and interpretation of diverse alteration zones. This approach and technology is also used forDirect Detection of Uranium Mineralization Zones relevant for subsequent field work.


Integrated Multi-Airborne Technology -- This is a new type of airborne survey that combines airborne magnetic, gravity, EM and radiometric in one survey. TerraNotes provides maps integrating the results to facilitate the development of complete 3D geological models.This approach cuts the time between reconnaissance and discovery by 2 to 3 years



NEW TECHNOLOGY


NEW AIRBORNE ELECTROMAGNETIC SURVEY CONFIGURATION
TerraNotes provides mapping for a new type of airborne survey configuration that combines the best of both world: mapping both deep and near-surface conductors at the same time. This is one of the most powerful and accurate time domain configuration on the market at the moment.


FAST INVERSION for LARGE DATASETS

TerraNotes, in collaboration with a well known university, has developed a solution and codes to significantly reduce storage and computational complexity of large linear, dense and ill-conditioned systems. The computational work for a typical iterative scheme is reduced from 0(N2) to 0(NLogN). Efficient numerical inversion schemes can be developed and are capable of dealing with a large scale inversion problem.


Applications for oil and gas exploration, mine exploration, groundwater and environmental applications. 
TerraNotes geophysics provices airborne surveys advanced data analysis, imaging, and interpretation.
