Quantum Downhole Systems Inc. is a Calgary-based company that specialises in fixing underpressured horizontal oil and gas wells using concentric coiled tubing technology. Their three main systems remove obstructions, clean away wellbore materials like sand and fines, and measure production data to help wells produce more effectively. With over a decade of experience and field-proven results in more than 1,350 wells across western Canada, the USA and Alaska, they work on multi-frac cleanouts, heavy oil applications, and drilling remediation. Consider referring wells with production problems caused by wellbore blockages or material build-up, particularly in underpressured or depleted horizontal wells.
