RWSS Real-Time Wellbore Strengthening Solution

Vertechs RWSS enhances wellbore stability in real time by introducing ULIA Ultra Low Invasion Additive, a non-permeable plugging material, into the drilling fluid. It forms a pressure-bearing barrier near the wellbore, sealing microfractures and micropores while drilling, reducing losses and improving drilling safety.

ULIA is a patented, polymer-free material with an optimized particle-size distribution and surface treatment. It is thermally stable up to 180°C and compatible with all types of drilling fluid systems, including water-based, oil-based, synthetic-based, and formate systems.

The patented HPIT High-Pressure Invasion Tester tracks drilling fluid sealing and pressure resistance in real time, supporting on-site evaluation and optimization.
