BOREHOLE GEOPHYSICAL SERVICES

Borehole Televiewer Image Acoustic and Optical

TELEVIEWER SURVEYS

We offer high quality optical and acoustic televiewer logging of boreholes, which include the following:

​

  • Borehole structure logging

  • Azimuth and dip of mapped structures relative to the borehole and to true north (oriented core)

  • Aperture of open features such as faults and fractures

  • Primary stress orientation of borehole by mapping dog earing features present along the borehole

  • Televiewer data can compliment visual logging of core by mine engineers and provide a more comprehensive understanding of the structure

  • Inspection of steel and PVC boreholes to identify anomalies/deterioration present along the borehole casing

Borehole Logging Setup

CALIPER SURVEYS

We offer acoustic and mechanical caliper services to provide the following:

​​

  • Borehole diameter​

  • Open fracture locations and widths for structure and potential water inflow mapping

  • Analysis of borehole deformation for stress analysis of the borehole

Borehole Winch Wireline

NATURAL AND SPECTRAL GAMMA

We offer natural and spectral gamma logging to provide the following:

​​

  • Stratigraphic logging of rock and correlation of stratigraphy across a site or regionally for aggregate resource exploration and development

  • Logging within sediment to map presence of sand, gravels, and clay deposits

  • Changes in mineralogy of bedrock for geotechnical or exploration reasons

APPARENT CONDUCTIVITY
AND ELECTRICAL RESISTIVITY

We offer conductivity and resistivity logging for the following:

​​

  • Stratigraphic logging of rock and correlation of stratigraphy across a site or regionally for aggregate resource exploration and development

  • Logging within sediment to map presence of sand, gravels, and clay deposits

  • Changes in mineralogy of bedrock for geotechnical or exploration reasons

  • Mapping of groundwater plumes vertically to aid in delineation and determine depths to set well screens

Full Waveform Sonic FWS Processing

FULL WAVEFORM SONIC LOGGING

We offer full waveform sonic logging for the following:

​​

  • Stratigraphic logging of rock and correlation of stratigraphy across a site or regionally

  • Compression and shear wave velocities of the rock

  • Engineering properties of the rock (Poisson's ratio, Shear Modulus, Elastic Modulus, Young's Modulus)

  • Bond logging of steel casing to ensure they are properly grouted for municipal groundwater wells

Hydrogeological Geophysical Processing

HYDROGEOLOGICAL LOGGING

We offer hydrogeolical logging, including fluid temperature/resistivity, flow meter logging, and water property logging for the following:

​​​

  • Mapping the hydrogeological flow regime present in the borehole

  • Groundwater protection and inspection of municipal groundwater wells

  • Estimating amount of flow from fractures along the borehole

  • Identify potential hydrogeological significant zones that can affect construction or mine development

Borehole Video Logging

VIDEO LOGGING OF BOREHOLES

We offer video logging of boreholes for quick inspections of boreholes to:

​​​

  • Identify large fractures within a borehole

  • Identify construction of and deficiencies within steel and PVC borehole casings

  • Identify zones of water egress into a borehole
