Learn how the unique gel structure of DELTA-TEQ drilling fluid mitigates your drilling risks.

When you are operating in challenging offshore wells, pore pressure (PP), fracture gradient (FG), and complex geometry can combine to create a narrow operating window. Numerous operational problems – such as excessive surge pressures, pressure spikes due to pump initiation pressures, complicated equivalent circulating density (ECD) management, and the inability to effectively control drilling parameters – can result in catastrophic events.

The DELTA-TEQ™ low-impact drilling fluid is a non-aqueous formulation engineered to extend drilling in narrow windows, helping you meet your objectives and minimize risks.

Advanced design

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

Viscosity clutch

In addition, the DELTA-TEQ low-impact drilling fluid has the unique ability to manage 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.

High-temperature formulation

In more extreme drilling environments, the DELTA-TEQ™ XT low-impact drilling fluid extends the operational range of our proven DELTA-TEQ fluids by providing superior cuttings suspension and protecting against sag in hostile, high-temperature environments.
