NSI Technologies (NSI) is pleased to announce that it will be presenting its new “cloud-based” version of the industry leading three-dimensional hydraulic fracturing design software, StimPlanTM. StimPlan is a complete and integrated software solution for hydraulic fracture design, analysis and optimisation. With a comprehensive integrated toolkit and the industry’s most rigorous geometry models, StimPlan helps operators worldwide maximise their well performance while lowering expenditure and reducing their environmental footprint, however complex their reservoir or fracture treatment design. Taking advantage of cloud-based parallel processing allows StimPlan to radically decrease the time required to run the multiple simulations required to achieve design optimisation. Post-frac benchmarking studies show that rigorous hydraulic stimulation design and treatment optimization helps both reduce operational problems and significantly improve well performance. Through optimizing the hydraulic fracture treatment, StimPlan? helps operators not only increase production but also drive down well costs through savings in proppant, pumping, and water disposal.? With an ever-increasing emphasis on minimizing the environmental impact of oil and gas exploitation, StimPlan? also helps ensure environmentally responsible hydraulic fracture operations. “For the last four years, NSI has been developing the new cloud-based version of StimPlan, including intensive beta testing over the past year,” said Dr. Michael Smith, NSI President. “We are thrilled to provide the industry with a set of engineering tools that will simplify the workflows associated with designing hydraulic fractures in complex, unconventional reservoirs, and will significantly improve the ability to optimise reservoir economics.”? Easy Data Handling and Analysis – StimPlan? incorporates easy tools for importing, editing, and analysis of all the log, pressure, and rate data required for fracture design. Comprehensive databases for fluid and proppant data are also available. Pre- and post-frac analysis tools include well test analysis, minifrac analysis, step down test analysis, and production decline analysis. Rigorous Fracture Geometry Modeling – A range of fracture geometry simulation options are available within StimPlan?, from quick-look pseudo *D methods to fully *D gridded methods for more complex problems. The advanced fully *D finite element simulation ensures that fracture geometry is rigorously modeled, giving more accurate geometry estimates, particularly in complex multi-layered formations. Automated Treatment Schedule – No one has time to create a pump schedule through trial and error. StimPlan? can calculate this as part of the design process, resulting in a reduction in the time required to generate and select an effective treatment schedule. Post-Frac Production Analysis – Post-frac production can be predicted using a range of analytical methods. Alternatively, for more accurate predictions of well performance gains, pre- and post-frac production can be modeled using the *D numerical reservoir simulator integrated into StimPlan?. Economics and Fracture Optimization – The StimPlan? fracture optimization module integrates fracture geometry modeling, reservoir simulation, and economics to provide detailed production and economic evaluation. This helps maximize well performance and profitability from a planned treatment.
