Level Measurement Precision In North American Oil Fracking

A newly discovered oil patch in western North America uses Siemens level technology during oil and natural gas extraction. SITRANS LR250 continuous radar for liquid level measurement plus Pointek CLS200 capacitance point level offer a winning combination in this application.

Hydraulic fracturing, or ‘fracking,’ is a process of creating fractures in rock using pressurized fluid. Companies use this technique to extract substances like petroleum or natural gas.

This North American oil company pumps fracturing fluid – in this case, water – into a drilled hole until the pressure formed is strong enough to fracture the rock. Once the rock cracks, operators inject a ‘proppant’ into the fracture, typically sand. The proppant keeps the crack open once the pressure is reduced.
