Successfully drilling challenging wells requires an in-depth understanding of the hydraulics during all phases of the operation. The drilling process is highly dynamic and complicated to model; thus, much of the dynamics have traditionally been neglected. However, with diminishing operational margins, the impact of dynamic effects is growing. Coupled with increasing well construction costs, modeling the dynamics becomes essential and strategically important.

Simulations performed in Drillbench dynamic drilling simulation software are key feature to replicate a real drilling operation and provide accuracy not possible with simpler steady-state models. Drillbench software provides a user-friendly tool that targets all drilling engineers involved in challenging wells. The software is built around the well-control workflow, covering pressure control, well control, and blowout control.

Drillbench 2025 new features

New functionality in 2025.2

Drillbench? 2025.2 includes an upgrade from Olga? dynamic multiphase flow simulator 2025.1 to Olga simulator 2025.2.1, which resolves stability issues reported by users in certain complex flow scenarios. In addition to the engine upgrade, this release introduces new plotting capabilities, workflow enhancements for Drillbench dynamic well control and Drillbench blowout control, and targeted bug fixes across all modules—including resolution of several issues that were previously documented in the Known Issues section.

Upgrade to Olga 2025.2.1

The Olga simulation engine used in both Drillbench dynamic well control and Drillbench blowout control has been upgraded from version Olga 2025.1 to Olga 2025.2.1. This upgrade accumulates improvements from two intermediate engine versions between the previous and current release, in addition to the targeted stability fixes described in the release overview. Relevant improvements include corrections to multi-phase flow calculations in counter-current scenarios—such as kick migration and u-tubing events—improved robustness for certain pipe geometries and fluid conditions that could previously cause unexpected simulation failures, and improved handling of fluid properties at phase boundaries. For simulations started from a previously saved state, unnecessary reductions in simulation time step at startup have also been eliminated.
