Dynamic simulations provide unique insight into well hydraulics during drilling operations and well control scenarios. Simulators are an invaluable tool to improve understanding of advanced MPD operations, well control, and HPHT challenges in general. Kelda's advanced software solutions offer comprehensive training tools for HPHT/MPD fundamentals and well control, enhancing the skills and knowledge of drilling crews.

Advanced hydraulics simulations

LeidarSim is a highly configurable high-end multiphase well simulator with full pressure and flow dynamics, rigorous fluid definitions – including multi-fluids, capable of simulating most MPD/UBD/DGD operations and contingency scenarios such as influx handling.

Highlights:

State-of-the-art multi-phase drift-flux model
Non-linear fluid rheology, such as Herschel-Bulkley
Compressible and expansive drilling mud
Non-linear PVT for gas phase phase

Using advanced, realistic dynamic simulators, one can replace in-casing operational training of MPD crew with simulator-in-the-loop (SiL) training using the actual MPD control system. This enables crew training of operational procedures like connections and tripping off critical rig time and without risk. With a multiphase simulator, the crew can also practise critical well control scenarios that are not possible on a real well. Kelda's simulators provide comprehensive training tools for MPD crews to enhance their operational skills and safety.
