Frequently asked questions
Do we require additional mud pumps, drill strings or other equipment to use the DeviDrill?
No, the DeviDrill fits directly on the standard drill string and operates with similar flow rates as the regular N-sized wireline core barrels. During drilling the DeviDrill is rotated by the drill string at normal speed, typically 7-900 RPM, while at the same time steering the hole in a predefined direction and collecting core samples.
How sharply can the drillhole be turned when utilising the DeviDrill?
We recommend an average turn of 9° per 30m drilled, or a radius of about 200 meters, to make the directional drilling efficient while avoiding excessive wear on the drill string.
How much savings can be expected from using DeviDrill?
Savings can come in many forms, including reduction in drilling metres leading to direct time & cost savings and indirect cost savings due to reduced core handling and logging, fewer drill sites leading to cost & environmental savings, and consistent target accuracy leading to cost savings. If you have a project where you believe directional coring could be used, we recommend contacting us. We prepare directional proposals at no cost, making it easy to see the benefit of DCD in your specific case.
