Schlumberger Drillbench 2022.2.0 Build 1214

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.

Recent enhancements

-Integration of well paths directly from the Petrel platform.

-Reading pore and fracture pressure from the Techlog platform.

-Support for dual gradient drilling with a subsea pump.

-Improved modeling of managed pressure drilling.

-Strengthened dynamic surge and swab calculations.

-Rigsite Kick—a standardized kick sheet for operational rigsite use, based on robust well control modeling and simulation.

With challenging wells becoming commonplace, more advanced simulation tools are required to plan and operate them with an acceptable risk. Increased complexity decreases margins, making accurate transient models even more important.

Drillbench Blowout Control, powered by the OLGA multiphase flow simulator, enables drilling teams to perform dynamic analysis of possible blowout rates; kill rates in different scenarios (through the drillstring or relief wells), including required pumping volumes and duration; and pressure loads.

In addition to relief well planning, Drillbench Blowout Control is valuable for training, operational follow-up, post-analysis, and reporting.

Drillbench Blowout Control technology provides proven solutions for contingency planning, operational support, and environmental risk assessments.
