Prevent Formation Damage & Improve ROP
By modeling pressure profiles before and during drilling, UBDPRO helps prevent overbalanced conditions that can cause formation damage, lost circulation, and reduced production. LINQX engineers can customize your software to streamline workflows and keep your wells producing—request a demo today.
When precision pressure control is the difference between a successful well and costly downtime, UBDPRO is the trusted hydraulics calculator for underbalanced drilling (UBD) and managed pressure drilling (MPD) operations.
This powerful underbalanced drilling hydraulic modeling tool helps drilling and completion engineers design, simulate, and optimize compressible fluid hydraulics while maintaining precise bottomhole pressure control.
Your Go-to MPD Hydraulics Tool
UBDPRO goes beyond conventional models with advanced two-phase flow modeling, gas injection rate optimization, and annular ECD modeling, giving you the insight needed to:
- Prevent formation damage in sensitive reservoirs
- Maintain stable choke pressure during drilling and tripping
- Improve rate of penetration (ROP) in hard rock drilling with air/mist fluids
- Ensure effective cutting transport in complex trajectories
Designed for Engineers in the Field and Office
Built for drilling and completion engineers and operations supervisors who need accurate, fast answers for complex MPD and UBD operations.
- In the field: Use UBDPRO as your MPD hydraulics calculator to adjust choke settings and injection rates in real-time
- In the office: Run pre-job two-phase flow simulations to design safer, more efficient drilling programs
Whether you’re designing a foam breakdown to mist sequence or preventing gas migration in a depleted zone, UBDPRO gives you the accuracy and control you need.
