DeviDrill

The DeviDrillTM is a steerable wireline core barrel, fully compatible with the NQ wireline system.

The Devidrill reduces the cost of exploration drilling programmes by hitting targets quicker and more accurately than with traditional core drilling methods. By making multiple branches from a mother-hole it dramatically reduces time and cost and in addition you get geological information from where you want. No time is lost moving the drill rig, drilling through overburden and drilling further down to where you almost where with the previous hole.

As Devidrill uses a normal drill string so there is no need for additional water pumps, drill strings, or survey instruments. Devico’s survey tools are a fully integrated part of the tool, as they stay on board and measure while drilling. Coring during steering provides a complete record of the geology. It leaves nothing in the hole - except a bend. The curvature or dogleg can be adjusted from completely straight to more than 20 deg/30 meters. However, the recommended curvature from the drill rod manufacturer is 9 deg/30 meters, as any greater deviations will result in extensive wear on the drill rods.

DeviFlex non magnetic multishot.

If you know how to run your inner tube, you’ll know how to run your DeviFlex. It’s 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 constructed to be simple 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 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 will work in horizontal as well as vertical holes.

DeviFlex communicates with a PDA through a Bluetooth modem. The results can be viewed on the PDS screen in the field once the date is downloaded from the tool. The data can then be further processed in DeviSoft where it can be analyzed, plotted and reported to the client.
