Since 2003 Prime has pioneered underground intersect drilling, in which pilot holes are drilled from both the entry side of a crossing and the exit side of a crossing usually simultaneously with two drill rigs and meet underground in the middle of the track. To date Prime’s track record is a 100% success rate having completed more than 50 intersect projects, setting several world records along the way. Prime has completed intersect projects with heavy gravels on both sides of a crossing, to lower annular pressures in alluvial formations and to complete long reach HDD projects (more than 1,000 meter lengths).
