Robertson Geo has recently been involved in a project of detailed ground investigation on the seawall and surrounding area of Chesil Cove, Portland, England.
Downhole logging was used to successfully identify any key marker beds in the Kimmeridge clay and to locate basal shear surface and gauge the rate of any ground movement. The dip angle of the bedding was determined and groundwater conditions were assessed.
Tools applied included High Resolution Optical and Acoustic Televiewers, 3-Arm Caliper with natural gamma, Formation Density, Neutron Porosity and the PS Logger. All probes were deployed from one of the Robertson Geo fleet of purpose built logging vehicles using a 4-core 2,000m winch and Micrologger2 system.
