Products and Solutions

With more than 25 years of innovative and reliable products and design solutions for the upstream oil and gas industry, CBG offers a comprehensive line of downhole tools for Measurement While Drilling (MWD), Logging While Drilling (LWD), Wireline and Casing Inspection.

CBG is the leading worldwide supplier of MWD/LWD gamma tools. The probe based NGT-T gamma tool is the industry standard. Originally designed for the first Tensor system in 1993, it continues to lead the way in measuring naturally occurring gamma radiation emitted from the formation surrounding the drill bit.

CBG’s smaller diameter scintillator gamma tools meet design requirements for newer collar mounted applications. The NGT-075 is the smallest diameter scintillator gamma on the market at only ¾” OD. The NGT-CSX and NGT-CSX-B at 1.05” OD, are still small enough to be mounted within the drill collar but with a higher sensitivity.

CBG also supplies directionally sensitive or “focused” gamma tools such as the DGA, DGA-C and the new Dual-Detector, DDG for Azimuthal gamma measurements.

In addition to our catalog of standard CBG gamma sensors, we are ready to work with your engineers to develop custom designed technology solutions to meet your specific requirements. We have designed and currently manufacture nearly 20 custom gamma tools for customers around the globe.

CBG products also include Wireline Natural Gamma Ray and Induction Collar Locators for accurate depth measurements for both open-hole and cased-hole logging applications.

More than simply detecting the presence of casing collars, the patented ICL, Induction Collar Locator also serves as a casing inspection tool. An electromagnetic measurement utilizing the technique of remote field eddy current testing (RFT), measures other mechanical features of the casing such as wall thickness variations caused by corrosion or perforations.

Expanding on the success of the ICL, CBG developed a larger scale version of the tool for large diameter water-well casing inspection, the CITM or Casing Inspection Thickness Measurement tool. It is the only water-well casing inspection tool capable of simultaneously measuring casing weight, internal casing diameter, collars, centralizers, perforations and internal or external corrosion. The CITM provides valuable information on casing irregularities often missed by video mwd surveying tools.

As Directional Drilling continues to push the limits with faster ROP and longer laterals, these tools must also continue to improve to meet these real time data and data rate challenges. CBG goes to great lengths to ensure its products are reliable and up to the challenge with advanced in-house testing. Utilizing the recently installed HASS environmental test chamber, every CBG product is subjected to extensive high temperature and vibration testing to ensure reliable drilling fluid and drilling tools performance and data transmission from the start of the job through its completion.

Enhanced Reliability Tests

Introducing CBG’s latest commitment to insuring the most reliable downhole tools on the market. The recently installed Thermatron HASS chamber enhances our ability to more accurately simulate real drilling environments with simultaneous 3-axis vibration and temperature profiles. Every CBG tool is tested under severe conditions to insure their reliable success during drilling or logging operations. No other equipment supplier takes their products reliability more seriously than CBG.
