Reduce downhole losses, increase flow rates, and extend the critical drilling window
In high-value offshore wells, you use drilling fluids with low equivalent circulation density (ECD) to protect the formation. But, low-ECD fluids are still susceptible to barite sag and surge pressures. Once a well starts taking losses, the cost of pushing more fluid—and the hidden cost of a slower rate of penetration (ROP) and increased non-productive time (NPT)—can get out of control.
DELTA-TEQ™ low-impact, non-aqueous drilling fluid outperforms typical low-ECD drilling muds to help you avoid losses and extend the drilling window.
Low hydraulic impact
The low hydraulic impact of DELTA-TEQ drilling fluid absorbs pressure spikes and surges. This protects the wellbore, helps stop losses, and keeps you consistently in the drilling window. Sag-resistant properties keep solids suspended, even when the fluid column is static. So you retain fluid integrity if you have to shut off the pumps and pause operations.
Advanced formulation lets you use the DELTA-TEQ fluid system in both drilling ad liner runs without risking formation damage from surge and swab pressures. The result is an intact wellbore and a reduction in overall costs. The unique formulation delivers consistent performance across a wide range of temperatures, and is easily modified and adjusted to suit regional environmental requirements and regulations.
The core advantages of using DELTA-TEQ drilling fluid in high-value, offshore wells include:
- Reducing downhole losses and NPT
- Increasing flow rates and ROP
- Extending the critical drilling window
