US/Canada based companies

1. General Electric Energy – Drilling Measurements (GE + Sondex)

This company has involved in the oilfield industry for more than 30 years now. They are manufacturing many oilfield equipment used by leading operators and service companies in the world. At the beginning they only provide the well known positive pulse Tensor MWD system, but due to their acquisition of Sondex few years ago, they now have the negative and electromagnetics MWD systems. Besides MWD tools, GE also provides LWD systems, like Gamma Ray and Resistivity tools. How about the price? That all depends on your requirements, whether you need for directional only, directional + gamma, or directional + gamma + resistivity. Just contact one of their representatives nearby you for more information about the price and the support.

3. CBG Corporation

The Geosteering Resistivity Tool (GRT) is an advanced imaging laterolog device, incorporating four independent receiving electrodes to create an azimuthally-sensitive resistivity measurement. This capability allows the GRT to detect a nearby bed, determine whether it is conductive or resistive, and ascertain Modeled GRT current density its direction and distance. Unlike competing tools, it is not necessary to rotate the GRT to obtain directionally-sensitive resistivity measurements.

Benefiting from its innovative electronic and mechanical design, the GRT provides accurate and reliable operation, combined with low cost and serviceability. Sophisticated self-calibrating measurement circuitry ensures that stability and precision are maintained across the full range of operating conditions. Should it be necessary to service or repair the GRT, its rugged, probe-based construction makes disassembly and reassembly quick and easy. The GRT does not employ any third-party proprietary technology so there are no licensing fees required.

The GRT can be provided as a stand-alone tool, or part of a complete LWD resistivity system, including a surface display, display software, and data communications/control electronics. A mud Pulser can be mounted above or below due to the full 10-wire bus passing through the tool. The GRT is available compatible with Tensor-type systems, and can be readily integrated into other industry-standard tool strings. A built-in Muleshoehelix at the top end of the tool ensures that the Directional Sensor package GRT Maximum Detection Distance is always correctly oriented with the GRT sensors.
