As with all DeviGyro based survey solutions, quick, comprehensive, high precision, continuous surveying is made possible with the DeviGyro Overshot Xpress (OX). With the added ability to retrieve the core tube during the survey, the OX truly enables surveying to become a part of the drilling cycle and therefore increasing overall drilling productivity.
In combination with the DeviCounter, the OX performs continuous surveys at speeds of up to 100 m/min. Survey data is recorded at a sample rate of 10 shots per second, both while the instrument is lowered down the drill string to attach to the core tube, and while in the process of retrieving the core tube to the collar. Effectively completing 2 independent survey runs as per the Devico standard, to provide additional quality control.
At the completion of each survey all data is passed through an automatic, stringent, at-rig QA/QC process with a comprehensive pass/fail criteria, quickly providing the operator with full awareness of the survey results, and drill hole position. Equipped for the next step in the drilling process.
Though the OX is the ideal borehole surveying solution for both surface and underground diamond core drilling applications, its short 1.2m length eases overall handling and therefore makes it especially beneficial for surveying underground and in other confined space environments.
DeviGyro Overshot Xpress, your choice for minimizing the impact that surveying has on drilling productivity and maximizing bit-on-face time.
