Drillbench 2025.1 is Available Now
Tuesday, 08 July 2025
Drillbench™ 2025.1 introduces major new functionalities, including support for mud-gas separator (MGS) modeling to simulate rig safety equipment during well control events, interactive kick intensity adjustments for reservoir pressure management, and enhanced reservoir modeling with options for linear productivity index (PI) and reservoir model definitions. The release also includes an upgrade to the Olga™ dynamic multiphase flow simulator for improved drilling solutions and adds back pressure management as an option in managed pressure drilling simulations, enabling users to manipulate annulus pressure for well control.
Drillbench 2025.1 introduces MGS modeling, using the separator functionality from the Olga simulator, to simulate the behavior of key rig safety equipment during well control events. It enables users to configure a vertical separator tank, define flare and mud outlet lines for gas venting and liquid discharge, and calculate frictional pressure losses and separator internal pressure. The module provides real-time estimation of mud level, automatic detection of liquid seal breaches, and level regulation logic to prevent instabilities. Users receive notifications for underfill conditions when the mud outlet is closed due to low liquid levels.
Kick intensity in Drillbench 2025.1 functions as it did in Drillbench 2022.1, allowing users to specify additional kick intensity for the reservoir during interactive mode. Users can enable and define kick intensity through a checkbox and field, and adjust it during simulation by pausing, updating, and restarting the simulation. This feature permits changes in kick intensity to dynamically affect reservoir pressure.
The reservoir model in Drillbench 2025.1 maintains the same functionality as in Drillbench 2022.1, enabling users to switch between linear PI and a reservoir model using a radio button to define flow characteristics. When selecting the reservoir model, users must input permeability if the influx phase is gas, and both permeability and oil volume factor if the influx phase is oil, with the default oil volume factor set to 1.0.
The Olga simulator has been upgraded to the current version, Olga 2025.1.
Enhance the simulation by adding back pressure as a managed pressure drilling (MPD) option In Drillbench 2025.1, back pressure in an MPD setting and is represented as annulus pressure at the surface within the simulation mode. Users can adjust this back pressure during interactive simulations, through the simulation control interface, enabling them to increase annulus pressure to achieve an over-balanced well and stop influx. Additionally, the back pressure can be modified in the run configuration table, providing flexibility in managing drilling conditions.
The product is suitable for use by production, process, and flow assurance engineers, and those involved in multiphase flow simulation.
