• Description

    DeviFlex™ is a non-magnetic electronic multishot for surveying inside casings and drill strings by simply using the wireline system. Mgnetic disturbances will not influence the tool at all and it is designed for easy to use. Just pump the tool into the hole and pull it out in given intervals. No adjustments are necessary.

    The DeviFlex™ tool consists of two independent measuring systems. Three accelerometers and four strain gauges are used to calculate inclination and change in azimuth. In addition, the DeviFlex™ records and stores gravity vector, temperature, and battery capacity.

    The DeviFlex™ fits casings and drill strings from B-size and up to P-size. You need one instrument and a set of sleeves with various wheel sizes to adjust for different hole dimensions.

    The tool has been proven to work in horizontal as well as vertical holes.

    The DeviFlex™ communicates with a PDA through a USB-modem. The results can be viewed in the DeviSoft Mobile software on the PDA in the ?eld once the data is downloaded from the tool. The data can thereafter be further processed in DeviSoft™, analyzed, plotted and reported to the client or given directly to the client on a memory stick.

    Warranty: The DeviFlex™ is covered by the unique, extended Devico Profit Advantage Warranty (PAW) Programme.
