Geophysics equipment: supporting team BGC in the field

Early this year, BGC opened a new 4,000 square foot warehouse in Calgary with geophysical equipment to support the work of our team on various BGC projects. Many clients are familiar with our use of electrical resistivity tomography (ERT) and seismic refraction techniques to inform the design of trenchless crossings on pipeline projects; but our expertise and equipment extends to a wide variety of other applications.

Our downhole logging experts, offer a wealth of knowledge regarding our standard logging techniques and some of the lesser-known downhole applications, including nuclear magnetic resonance (NMR), distributed temperature sensing (DTS) and discrete fluid sampling.

Equipment in our new warehouse also includes a fleet of unmanned aerial vehicles (UAV), equipped not only for standard photogrammetric work but also for carrying a range of different sensors, including multispectral and thermal cameras and a high sensitivity magnetometer. BGC has certified UAV pilots in house and although we don’t operate crewed aircraft; we are experienced in the processing of airborne EM data for larger scale mapping applications.

BGC not only works on land and in the air, but we also have extensive waterborne capabilities. Our team has a wealth of experience conducting waterborne EM and ERT surveys over freshwater bodies, including for mapping saline seeps discharging into rivers and ponds. We also have side-scan sonar equipment and a marine seismic system which we’ve used for geohazard work along coastal pipeline projects and for some trenchless crossing designs also for pipeline projects.
