Products - Quartz Downhole Gauges

CalScan's Wolverine class of quartz downhole tools provides the oil field industry with superior data, reliability and performance.

The Wolverine is designed to work with the Quartzdyne quartz transducers. It has surpassed industry standards by being the first quartz tool to operate using only one 3.6 volt lithium cell (for temperatures under 150°C) or two cells (for temperatures over 150°C).

The Wolverines accuracy of 0.020% FS is slightly better than the Badger and Mole silicon crystal tools at 0.024% FS, but with significantly better long term stability and resolution. For long term tests at elevated temperatures over 140°C we recommend our Wolverine for this reason.

The Wolverine takes advantage of improved quartz resolution by allowing a sample rate to 1/10th of a second, yet maintains the same resolution as our Badger and Mole silicon crystal tools. This advancement allows the operator to capture fast pressure pulses, for example when fracturing a well, that other downhole recorders would miss.

CalScan Services strives always to build user-friendly products. By integrating the same software package and the same interface box that programs and downloads all the data from our tools, we have made the transition between our tools seamless.

The Wolverine's housing is made of 718 Inconel, the same metal that is often used on the turbine blades on military jet engines. The high temperatures on the turbine blades will cause most metals to oxidize in the presence of oxygen, 718 Inconel was designed not to. As a result its one of the most durable steels in the potentially high temperature and corrosive environment of a well. It is one of the few recommended by NACE 2002 for use in H2S sour conditions. Since we began manufacturing tools we never have had one failure from metal corrosion.

We take all our tools through extensive testing at elevated temperatures in order to provide you with a tool that will stand up to the rigors of the oil field.
