DrillStream's Abrasive Jet Drilling technology promises to change the face of the drilling industry. Abrasive Jet Drilling technology with steel abrasives has been around for decades, and has been proven to deliver substantial increases in ROP. The density of drilling fluids containing up to 10% steel concentration is extremely high, and both pressure profiles and equivalent circulation density can be very volatile. DrillStream's unique and proprietary recirculation capability reduces the amount of abrasives circulated throughout the entire well by an order of magnitude. While the additional solids still require due consideration, the unique technology moves these issues firmly into the realm of the practical.
