ROUND SHANK BIT FOR OIL EXTRACTION IS RECORD BREAKER

The investigation and exploitation of unconventional sources of oil such as oil sands and oil shale is a matter occupying many industrial countries – all the more so as the oil price rises and conventional sources of oil dwindle. Technical advances and better and less expensive methods of extraction are turning unconventional sources of oil like these into exploitable deposits – even if in this regard we are still at the very early stage ...

There are deposits of oil sand all over the world, with the largest being in Venezuela and Canada. Oil sand deposits could make up around two thirds of global oil resources. In Canada there is thought to be oil sands under an area of over 140,000 square kilometres – an estimated one third of global oil deposits. Experts believe that the sands contain at least 175 billion barrels of crude bitumen that can be extracted using modern technology.

On average you need two tons of oil sand to produce one barrel (159 litres) of crude oil. The average cost of extracting the oil sand is just under 20 dollars a barrel. By the time it is converted into synthetic crude oil, the price climbs to around 40 dollars. As well as sands, clays and water, oil sands consist of hydrocarbons, with the level of hydrocarbon content ranging up to twenty percent. At 12% and above it is deemed to be ‘rich’. Discovering the deposits, though, is only half the job. It is only with suitable conveyor and extraction technology that mining it becomes interesting. When working oil sand, the breakers suffer extremely costly wear and tear caused by the clay and silicon elements that it contains. Betek – globally recognised as innovative consumable parts specialists – develops economic tool solutions for just such machines. The result in this case breaks all records: Betek provides for this task the largest and most expensive round shank cutter bit that the company has ever made!
