First Guyanese drilling machine - Successful launch TERRA-JET DJ 10
1st training borehole This first shot for the connection of a DN 90 mm HDPE delivery pipe for a new building, had to cross a river 3m below its bed, i.e. at a depth of 6m. In this particularly soft ground, the speed of the drilling arm moved by TERRA's patented double cylinder direct drive was decisive in making the drilling head 'bounce' and deflect in this very soft ground.
2nd formation drilling This shot was a test for the customer. He wanted to try his DJ 10 in the hardest terrain in his area. This dry and compact laterite was very hard. The 1'800 Nm of torque and the 4 to of thrust combined with the TERRA drilling tools, made this ground friable and allowed the drilling to be carried out without any problems.
3rd training borehole This drilling, for the installation of a DN75 mm HDPE delivery pipe, had as a condition to emerge immediately in the bank of the deep crossed river. While passing at a safety distance of 2 m minimum under its bed. The road along the stream could not be closed to traffic. The 20 m permissible bending radius of the drill rods was exploited and made this job possible and easy. The stream crossed would be 25 m long. This portion of the pilot shot, the most accurate, was inaccessible for detection. Thanks to the good preparation of the site and the drilling plan generated by the TERRA Bore Planner software, the drilling team only had to respect the instructions of the drilling protocol to successfully reach the objective.
