Tracking Systems: Walkover locators and wireline systems
Radiodetection’s itrack tracking and guidance system for horizontal directional drilling machines keeping a bore on track, on time and within budget. The system comprises an itrack Receiver, a DataView unit, one or more DataSonde and Radiodetection’s Borelog software. With a single operator and remote steering, there is no need to dig trenches and roads and rivers can be crossed without costly disturbance to daily traffic using the itrack. Remote steering LED display allows the drill head operator to see where the drill head is and to compensate to keep on track. Accuracy is assured – depth angle and heading are all displayed to the operator. 877.247.3797, www.radiodetection.com
Underground Tools Inc.
Underground Tools’ new sonde housing showcases a ¾-inch thick access door on the sonde housing for superior protection of valuable electronics. The housing is as much as 33-percent thicker than comparable units and features a slightly larger body diameter for greater wear resistance and durability. The housing incorporates a 7-hole Vermeer pattern that is compatible with UTI pilot bits, including UTI Gold Series bits or Vermeer pilot bits. Custom adapters allow the housing to be used with all makes and models of drill rigs. 866.488.3478, www.undergroundtools.com
Sharewell’s new steering tool is a directional guidance system specifically designed for HDD applications that provides both directional survey information and annular pressure while drilling. The system operates with TruTracker to provide critical drilling information including: inclination; tool face; azimuth; position; temperature; and annular pressure. The system can be operated with or without the pressure sensor. When operating with pressure, a special pressure sub is required for the bottom hole assembly. The advantage of a steering tool that monitors the pressure of the annular area of the hole is if the pressure reading decreases, it could indicate a potential frac out; however if it increases, it could indicate a potential formation falling into the bore hole, possibly causing sticking of the assembly in the hole. Steering tool components include the probe, drillers console, interface, computer and printer. 800.637.6461, www.sharewell.com
