DeviFlex™ — Non-magnetic system with new Auto-Rotate centralizers for Surveying inside rods with the highest Precision

NEW: Devico is releasing the Auto-Rotate DeviFlex option – adding significant value to the DeviFlex through less manual handling. Survey accuracy is increased and survey time is reduced by more than 50%.

Survey inside your rods — Quick, Fast with high accuracy

If you know how to run your inner tube, you know how to run your DeviFlex. It is THAT easy.

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

No drift or fragile sensors, the DeviFlex is the perfect system for drillers

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, and the results can be viewed on the PDA screen in field once the data is downloaded from the tool. The data can thereafter be further processed in DeviSoft, analyzed, plotted and reported to the Client.
