Kaikōura Landslide Investigation, GNS
In November 2016 New Zealand experienced a magnitude 7.8 earthquake, situated 60km south of Kaikōura. Over $1.8billion of insurance claims resulted from this quake and extensive scientific research was undertaken. As part of that research, GNS was investigating earthquake induced landslides and requested RDCL’s geophysics wireline tooling to assist with modelling.
RDCL mobilised personnel and wireline tooling via helicopters onto several landslides near Kaikoura. We ran downhole geophysics tools through drill holes beyond the rupture surface of the landslides so GNS could better understand the mechanisms triggering earthquake landslides. The project required multiple mobilisations and had staff on-call to maximise weather windows across a wild and wet season.
RDCL provides the best wireline geophysics capability across New Zealand and offers a broad range of equipment. GNS required a highly professional, skilled team who could mobilise quickly to maximise schedules in a very tight drilling programme.
