Equipment Spotlight: Wireline Locators

September 2010 Vol. 65 No. 9

Wireline tracking technology from INROCK, Underground Tools Inc., Sharewell and Horizontal Technology.

INROCK
The Paratrack Guidance System utilizes an all angle, high resolution system that provides the driller with single guide wire tracking (surface or underground tacking); magnetic field tracking; parallel tracking (underground tracking of multiple parallel bores); intersections (tracking of two separate or multiple boreholes from varying directions); beacon tracking (wireless tracking); and pressure while drilling (measures annular and drill pipe pressures). 713.690.5600, www.inrock.com

Underground Tools Inc.
Underground Tools’ sonde housing showcases a ¾-inch thick access door on the sonde housing for superior protection of valuable electronics. The thick housing 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
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
