Our Geosteering Resistivity Tool made good logs in Carbonate Reservoirs in China. The formations have resistivities over 10,000 ohm.meters, and no other tool (even from the major service companies) was able to measure them accurately. The GRT logged the wells with no problems, and excellent correlation with Wireline Dual Laterolog tools was demonstrated.

CBG Presents Seminar on the Geosteering Resistivity Tool
October 2010CBG and Compass Directional presented a “Lunch & Learn” seminar to more than 50 Geologists and Drilling Supervisors in Calgary this month. The purpose was to introduce the revolutionary new service and to contrast the capabilities of the GRT with conventional Resistivity tools. The GRT is in service and drilling wells in Alberta. Customer feedback is very positive, with successful geosteering leading to better borehole placement.

Geosteering Resistivity Tool demonstrated in Montney Horizontal Well
February 2010A production version Geosteering Resistivity Tool (GRT) was demonstrated drilling a horizontal well in North-West Alberta during July 2009. The tool was run with a GE/Tensor navigation system and a Tolteq Surface System by Atlantic Directional Services Inc., of Calgary, Alberta. Real-time data were relayed through the Pason system to remote locations.
The challenging geosteering job showed how the tool could “see” the approach of the drill-string to a shale boundary, and indicate the direction to drill to stay within a thin reservoir zone. A Resistivity/Gamma log was also generated using the high-resolution data stored in the tool memory.

New Gamma Tool is designed for use in Heavy-weight Collars!
September 2009The NGT-CN “third-generation” scintillator type gamma probe is now available. It will find applications where the NGT-T has been used, but can overcome the loss of counts caused by thicker collars, due to its larger scintillator crystal. It is dimensionally and electrically the same as the older tool, so it is a drop-in replacement.
Our “third-generation” technology consumes 40% less power from expensive lithium batteries while providing almost double the count-rates and retaining CBG’s exceptional temperature stability. More information is available on our NGT-CN webpage.

Geosteering Resistivity Tool finds OIL in Horizontal Well ! ! !
December 2008
A pilot-series Geosteering Resistivity Tool (GRT) was deployed in drilling an onshore/offshore horizontal well in Canada during November/December 2008. The tool was run with a GE/Tensor navigation system over a continuous logging period of 5-1/2 days without a failure by Meridian Directional Services Inc., of Calgary, Alberta. Commercial quantities of oil were discovered in several zones, which are now being completed.Real-time data, displayed by our patented Vector-Resistivity software, proved valuable in steering the well and in analyzing the formation properties. The target formation was Dolomite with a resistivity varying from 10 ohm.meters to more than 10,000 ohm.meters, where Wave-Propagation types of tool are inaccurate. The GRT uses an Imaging Laterolog measurement which can reliably operate over a very wide range of formation conditions. Real-time data was transmitted by mud-pulse telemetry from measured depths greater than 14,000 feet. High-resolution data stored in internal memory was recovered after drilling was complete, and translated into a detailed LAS file using our proprietary software, for analysis by oil-company geophysicists. More tests are planned in the near future. Click to view the field test photo album.
Production has started of the 4-3/4” version of the tool, for delivery in the second quarter of 2009.

GRT to be demonstrated at the Calgary Global Petroleum Show
June 2008CBG will return to the bi-annual show with our Geosteering Resistivity Tool actually operating on the stand. The complete system, including a Tolteq surface display running our unique patented directional resistivity graphics, will be shown. Resistivity information is color-coded and the directional component is referenced to toolface direction. Advance warning of the approach to a reservoir boundary is provided up to four feet away. A driller will be able to use the system to “steer the bit” in real time past shale beds or above oil-water contacts without needing any complex log analysis. The tool is the first to be designed at an affordable price for directional drilling companies.
Of course, we will also show the latest developments in our industry-leading gamma probes, including our new 0.75-inch diameter version!

CBG introduces a new generation of Gamma Tools for MWD/LWD
May 2008The first version of our “third-generation” scintillator type gamma probes is available in a diameter of only 0.75 inches. It will find applications in collar-mounted assemblies, azimuthal (directional) sensors, and small-diameter (under 3.5 inch) MWD systems. Larger diameter versions will be announced in the near future.
Our “third-generation” technology consumes 40% less power from expensive lithium batteries (only 0.28 watts!), while providing increased count-rates and retaining CBG’s exceptional temperature stability. More information is available in the brochure.

Successful test of GRT at GTI Catoosa Test Facility !
March 2008The Geosteering Resistivity Tool successfully logged accurate resistivity data in the Rhonda#9 well, comparing very favorably with the best available wireline log (a Schlumberger SFL). The GRT is an Imaging Laterolog type, with a depth of investigation similar to the LLd (deep laterolog), but with a better borehole response similar to the SFL (spherically focused log). Using the tool in memory mode rather than mud-pulse mode, the log was run and downloaded to a computer in LAS format. It was merged with the SFL log from an offset well for comparison purposes. Click to see actual log in PDF format.
We thank the professional staff at Catoosa for their generous assistance in making the test possible!

CBG Products copied but never equaled
September 2007They say that imitation is the sincerest form of flattery. Well, it isn’t flattery when someone copies your tool design, manufactures it with inferior or low-quality components, and then under-cuts your prices! It hurts even more when customers are surprised to hear that CBG didn’t “copy” the competitor’s product. We have had this experience with our MWD Gamma tool (NGT-T), which we designed originally for Tensor (our neighbors here in Austin, Texas) some twelve years ago. We have since sold over a thousand of them, but for three years Canadian customers at the Calgary Global Petroleum Show have commented that our tool “looks just like one from another Texas company”, and ask if we had copied theirs! All we can say is that several copies of our designs have appeared in recent years, but when you look at our proven performance, competitive pricing, and service record, the others don’t stand up to the comparison. No-one else is investing in the engineering effort to customize designs, or to create new products that develop new markets for the directional drilling community. Look for CBG to lead the industry with the next generation of tools!

New Sales Milestone for Gamma Probes!!!
July 2007CBG has sold more than 1000 of our NGT-T MWD/Geosteering Gamma-ray tools, which are successfully helping drilling operations worldwide. We have also sold hundreds of other types, such as the slim diameter (NGT-CS) and the directional tool (DGA). Of course, we continue to provide full support to our customers with fast-turn repair and calibration services. Other companies have copied our designs, but none have equalled the unique performance and reliability of CBG tools.

Global Petroleum Show, Calgary, Alberta
June 2006CBG participated in the Global Petroleum Show in Calgary, with an expanded booth that introduced the new Geosteering Resistivity Tool, GRT. The GRT which is scheduled to be commercial in early 2008 received a very positive response from all sectors of the drilling industry. Along with a graphical representation of the tool and its response, a new surface display was shown that incorporates directional Resistivity on the standard compass-rose drillers panel. Various gamma ray tools and the CBG Production Logging tools were also displayed.
