Drill Rigs Committed: 1
Geotech participated with industry partner, Gregg Drilling and Testing Canada, on a near shore geotechnical investigation drill program for the Aurora LNG project off Digby Island in Prince Rupert, British Columbia.
Geotech completed multiple mud rotary near shore boreholes, utilizing a casing advancer system to drill boreholes ranging from 13 meters to 45 meters, in water depths ranging from 6 meters to 30 meters. During the course of the program a multitude of geotechnical testing and sampling was completed, including; standard penetration testing, piston sampling, shelby tube Sampling, Nilcon Vane Shears, and cone penetration testing.
Wind, weather, tides, and working close to the shore and existing infrastructure presented challenges throughout this program. Although faced with these challenges, the drill program was completed ahead of schedule, under budget and with zero incidents.
This program involved a Fraste MDXL drill rig, seacans, anchor winches and ancillary equipment on a 50 m by 15m barge which required significant specialized revisions to satisfy the requirements of the project.
