In extended reach drilling (ERD) applications or long horizontals, pore pressure (PP), fracture gradients (FG), and well geometry can combine to create a narrow operating window. Numerous operational problems – including surge pressures, pressure spikes, poor hole cleaning or barite sag – can compromise your ability to drill the well safely and efficiently.

The DELTA-DRILL™ low-pressure-impact drilling fluid is a non-aqueous mud system engineered to extend drilling in narrow pressure windows, providing you with an Intelligent Fluids Solution to minimize risks while delivering on your operational goals.


Advanced formulation

Featuring an advanced formulation of specialized clay and polymers, the DELTA-DRILL low-pressure-impact fluid creates a non-progressive gel structure that reduces hydraulic impact with a rapid-set/easy-break profile. It maintains fluid integrity even when operations are paused and mitigates pressure spikes when circulation resumes—protecting the formation from surge pressures.


Viscosity clutch

The DELTA-TEQ fluid manages hydraulic impact by maintaining the right viscosity in the right areas of the well for optimal hole cleaning and penetration rates without putting excess pressure on the formation. Like a “viscosity clutch,” it engages viscosity at low shear rates and disengages at high shear rates for true optimization.
