54 DECEMBER 2023 WorldWide Drilling Resource® See us at Groundwater Week ~ Booth 1031 Advancements in Geothermal Drilling Simulation Adapted from Information by thinkPR Provider of advanced drilling simulation technology, Drilling Systems, which is part of training, technology, and simulation solutions leader 3t Energy Group, launched a next-generation DrillSIM Downhole Model to support realistic training for geothermal applications. The model has been implemented for the first time at the Drilling Simulator Celle (DSC), a research facility of Clausthal University of Technology (TUC), in Germany. Building on the operational success of the DrillSIM simulator, this next-generation downhole model will further enhance research and development capabilities of new and existing DrillSIM simulators to allow delegates to practice complex operations such as directional drilling, kick tracking, and stuck pipe, in a highly realistic and detailed virtual environment. Its new and improved key features include additional real-world data modeling, an advanced thermal and dynamic design, drill string vibration, a complex 3D well path, and increased focus on the transport of cuttings commonly found in deep drilling operations. Supported by funds of the Federal Ministry for Economic Affairs and Climate Action in Germany, this collaborative research project saw DSC elaborate the basic principles and mathematical formulation of the model which is based on simulations and experiments. This allowed Drilling Systems to develop and provide the DrillSIM API (Application Programming Interface) which allowed students to write and integrate programs to alter the behavior of the simulator. Working closely with TUC, Drilling Systems worked to advance the functionality of the API, building upon and strengthening the capabilities of the DrillSIM Downhole Model to support more complex and detailed operations. Harits Alkatiri, Ph.D. candidate at the university remarked, “We’re excited to be able to offer our students enhanced training that has the ability to simulate drilling operations of deep geothermal wells. With the ability to include possible problems one might encounter in such operation (caused by e.g. certain temperature development, kick, cutting transport, or even tool failures) in a high degree of detail, we are able to analyze and optimize such complex operation.” The DrillSIM downhole model allows operators to develop and run drilling and well control exercises while providing a graphical 3D representation.
