_ Hydraulic fracture modeling has become increasingly broad and interdisciplinary as it intersects with reservoir, production, well construction, geoscience, and data analytics. Modeling is used to run what-if scenarios for optimization and engineering design, synthesize diagnostics to characterize the subsurface, understand tradeoffs between variables, and improve our understanding of physical processes. Outstanding papers over the past year have addressed topics such as casing deformation, well spacing, frac-design optimization, proppant transport in the well or in fractures, integrating diagnostics from field trials, and exploring the effects of lateral length on production. While numerical simulation tools remain the dominant paradigm, an increasing number of papers are hybridizing data analytics and physics-based approaches. For many problems, data-driven approaches are applied. Technology developers face competing priorities—a desire for maximum physical realism along with a desire for large simulation domains, geological detail, fast runtimes, and rapid data integration. Because of these tradeoffs, a variety of solutions have emerged, each of which features relative strengths and weaknesses. Practically, the appropriate selection of tool depends on the availability of data and the degree of physical understanding (Starfield and Cundall 1988). In all cases, tool selection and design should be driven by the practical and theoretical problems that need to be solved.
