Leidar® Control System

Robust real-time controller for controlling bottomhole pressure, specialized for automated managed pressure drilling (MPD) and underbalanced drilling (UBD).

Straume® Hydraulics Simulator

Highly configurable multi-phase well simulator with full pressure and flow dynamics, capable of simulating most MPD/UBD/DG operations and contingency scenarios.

Bivrost Cloud Portal

Cloud portal for storing, viewing and reporting everything from simulation to field data.


Real-Time monitoring system for MPD and UBD drilling operations.


Remotely or locally control a shutdown of pumps, valves and other process-related equipment.

High Performance Actuators

Actuator solutions made to ensure high performance in dynamic control of almost any type of valves.

Kelda dpVertical

For estimating density. Typically placed in the vertical section on inlet or outlet.

Kelda dpFlow

For estimating flow, two-phase ratio and valve plugging. Typically used upstream and downstream of each choke leg.

Kelda UPS

With an uninterruptible power supply (UPS), the system can continue to estimate and keep downhole pressure constant during a full rihg blackout. The Leidar Control System is designed to have all critical sensors and actuators on UPS and traps pressure even if pump encounters a full stop directly.

Kelda Sensor Collection

Kelda can aid in selection, delivery and integration of fit-for-purpose sensors for any job, including pressure, temperature, level, flow, density, velocity and proximity sensors.
