Leidar® Control System

Robust real-time controller for high-performance bottomhole pressure control in automated managed pressure drilling (MPD) and underbalanced drilling (UBD) operations.

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.


Cloud based influx loss management envelope (IME) using rigorous PVT models.

High Performance Actuators

High-performance and precision rod-style electric actuator ideal for dynamic pressure control in hazardous areas.

Kelda dpVertical

Robust sensor for continuous density in and density out measurements in drilling operations. Unique capability to measure density in case of gas in the mud. Typically, installed on standpipe to measure density of the drilling fluid pumped down the drill string, and upstream choke manifold to measure return flow density in MPD operations. Particularly suited for low-footprint permanent installation on drilling rigs, both new builds and retrofit.

Kelda dpFlow

Custom-made for Kelda, 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 rig 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.


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

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.
