Devico - Directional Core Drilling and Borehole Survey Tools


Devico is a world leading company within directional core drilling and borehole planning. Along with high accuracy surveying instruments and continuous core orientation, Devico will ensure that you get the most out of your drilling programs. Devico does not only measure the boreholes, but also corrects them and steers them towards the planned target.

Directional core drilling can significantly reduce the total length of drilling needed in a project. By sidetracking a single mother borehole, multiple targets can be reached with a minimum of drilling, while no time is lost moving the drill rig. The accuracy of the steering process ensures that the targets are hit with high precision and thereby maximizes the information gained from a borehole.

Devico multi-shot survey tools give you reliable descriptions of your borehole trajectories in magnetic and non-magnetic rocks. Natural borehole deviation can be significant, so it is crucial to know where you are drilling for correct estimations of ore bodies and resources. Investing in, or hiring, a long lasting Devico survey tool is money well spent.

DEVIDRILL – DIRECTIONAL CORE BARREL

DIRECTIONAL-CORE-BARREL

The DeviDrill is a steerable, wireline operated core barrel. It has been used with great success both within the mining and construction industries worldwide. The ability to steer a borehole gives great benefits prospecting deep ore bodies, controlling natural deviation, keeping the borehole within given limits or hitting the targets with high accuracy.
The DeviDrill is attached to a normal drill string and is fully compatible with the NQ wireline system. 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. The DeviDrill is hired together with a technician.

DEVITOOL – MULTISHOT BOREHOLE SURVEY TOOL
BOREHOLE-SURVEY-TOOL

Devico's borehole survey tools have a rugged design, and are easy to operate and reliable. The DeviTools record inclination, azimuth, toolface, gravity vector, magnetic field vector and magnetic dip, as well as temperature and battery status. The Standard tool (30mm) fits inside all standard running gear.
The PeeWee is a miniature version (30mm) with integrated running gear perfect for surveying throughout drill bits.

DEVIFLEX – NON-MAGNETIC MULTISHOT SURVEY TOOL

DeviFlex is a non-magnetic multi-shot for surveying inside casings and drill strings by simply using the wireline system. Magnetic disturbances will not influence the survey results because of the tool’s technology. It can be used in a wide range of borehole sizes by performing minor changes in the tool setup. The DeviFlex is a cheap alternative for magnetic environments.

DEVICORE – CONTINUOUS CORE ORIENTATION

The DeviCore is a continuous core orientation system and a high-accuracy instrument that registers the orientation of the core and the inclination of the borehole. An orientation line with known position is scratched into the core as it enters the inner tube, and orientation is thereby provided over the entire core run. The results can be used to determine the dip and strike of bedding, foliation, cleavage, joints, etc.

DEVISOFT – BOREHOLE SOFTWARE FOR PC

The DeviSoft software is used in directional drilling and traditional borehole surveying. The software covers the needs of a directional driller and borehole surveyor. DeviSoft has functions for planning, registering and analyzing diamond drilled boreholes as well as grout curtains and blast holes. The DeviSoft program is included in the survey tool packages.

SURVEY TOOL RUNNING GEAR

SURVEY-TOOL-RUNNING-GEAR

In order to get the best out of your survey instrument you need a running gear. The Devico running gear can handle pressure up to 450bar and is very durable. The running gear comes in 36mm or 38mm diameter.
