APS Technology-AT-BIT INCLINATION AND IMAGE GAMMA RAY TOOL

Operating directly behind the drill bit, the iPZIG at-bit inclination and gamma ray tool provides real-time measurements that reduce directional drilling risk in critical hole sections. The early indication of changes in lithology, delivered by the gamma ray log, helps to accurately land horizontal wells.

Designed to operate as two separate subs, a lower sub, located directly above the drill bit, acquires data and transmits data to the upper sub, located above the drilling mud motor. The upper sub provides communication to measurement/logging-while-drilling systems.

The iPZIG can accommodate flexible bottomhole assembly (BHA) designs, and is compatible with any drilling mud motor. iPZIG provides the closest to the bit sensor offsets available in the industry and is the only tool to provide both gamma and inclination at the bit. These measurements are used to help determine well path placement and determine position in real-time while drilling.
