Our Geophysics group has been frequently profiled in the media for outstanding project work and innovative, cost-effective approaches.
Geophysical investigation methods are recommended for their efficient, cost-effective, nonintrusive, and non-destructive nature. WorleyParsons has developed innovative, leadingedge technologies and methods in-house to meet the specific needs of our customers.
Typical applications of surface and subsurface geophysical methods include:
- Exploration for metallic minerals and hydrocarbons
- Mapping overburden thickness in exploration programs
- Steam-zone monitoring for enhanced recovery of oil sands
- Groundwater exploration in fractured bedrock and in stratigraphic and alluvial aquifers
- Delineation of buried gravel deposits
- Geotechnical investigations of dam/berm foundations, including detection of seepage or defects in earth dams
- Tailings pond/dam assessments
- Characterization of pipeline corridors and river crossings
- Site investigations to detect, map, and monitor soil and groundwater contaminant
- Detection of underground cavities and caverns
- Landfill investigations
- Infrastructure investigations, including detection of buried utilities, pipes, and storage tanks
- Archaeological investigations
Our methods include ground-penetrating radar (GPR), magnetic, electromagnetic (EM), electrical resistivity tomography (ERT), very low frequency (VLF), gravity, and seismic reflection and refraction surveys. Borehole techniques include geophysical logging, pushprobe, vertical seismic profiling (VSP), and cross-hole ground-penetrating radar tomography. For large projects, remote sensing and airborne geophysical data support the ground geophysical surveys.
