Multi-Stage, Multi-Wellbore Hydraulic Fracturing Simulation in Naturally Fractured Reservoirs Using Cohesive Zone Model

Microseismic surveys have demonstrated the abundance of natural fractures where shear slippage occurs due to hydraulic fracturing. These natural fractures and their intersection with hydraulic fractures significantly complicate the optimization of hydraulic fracturing strategies especially in shale resources with multiple simultaneous or sequential stimulation stages. The clusters’ hydraulic connection within a stage may substantially influence the hydraulic fracture propagation pattern considering the highly variable perforation efficiencies of clusters. These complexities promote the proposed developments in our poro-elastic cohesive zone models for hydraulic fracturing in Abaqus.

SECURE, WEB-BASED ACCESS TO SIMULATION

As the world’s top OEMs can attest, simulation products are not created equal. Accurate, reliable, real-world results require a validated, proven simulation software package with years of research and development invested. These premier simulations demand significant computational hardware resources that are difficult and expensive to maintain. Simulation has become an absolute necessity to remain competitive in product design and engineering. To best optimize designs and contain development costs, engineers worldwide seek access to premium simulation software which, until now, may have been too costly to deploy internally.

DIGITALLY ACCELERATING ADDITIVE MANUFACTURING

While Additive Manufacturing (AM) has opened up possibilities for product design that were not even contemplated before, the industry still struggles with unknowns: part distortions, residual stress, and microstructure defects. The 3DEXPERIENCE platform provides a digital thread from design to simulation to production. Within this framework, engineers can perform detailed thermal-mechanical analyses to predict complex physics, such as microstructure, as-built material properties, and buckling. A faster eigenstrain-based simulation method is also available to obtain distortions for part compensation iterations. These simulation tools were awarded first place in residual stress prediction by the recent NIST AM Benchmark, and have been validated for a range of process types and materials.

PowerINSIGHT

As simulation capabilities have continually increased, the quantity of data produced exceeds the capacity of engineers to extract meaningful information in a timely manner. Little time is available for thorough analysis in increasingly tight design schedules. A wealth of information is barely examined by engineers leaving tremendous value on the table. Even if precious time is taken to extract meaningful results, sharing this information across and between organizations takes significant additional time and effort. This can often cause either product development delays or suboptimal product quality.

IMPROVING THE PRODUCT DESIGN & DEVELOPMENT PROCESS THROUGH SIMULATION

Unique, inherently transient Lattice Boltzmann-based physics allows SIMULIA’s PowerFLOW to perform simulations that accurately predict real-world conditions. Using the PowerFLOW suite, engineers evaluate product performance early in the design process prior to any prototype being built—when the impact of change is most significant for design and budgets.

Considering Print Direction in Topology Optimization to Minimize Overhang Constraints

One of the main design aims in automated product design especially for additive manufacturing (also called 3D printing) is to obtain designs having no need for support structures with respect to overhangs as shown below.

PowerTHERM

Thermal management is a critical aspect of vehicle design. When designing with ever-tight packaging and thermally sensitive electronics and plastics for weight reduction, components can exceed safe operating temperature limits and there is potential for systems to fail. Additionally, conditions can degrade nearby components leading to catastrophic durability, safety and warranty issues. Vehicle systems (such as the engine, transmission, HVAC, or power steering) have significant energy requirements and the related thermal efficiency has a direct impact on fuel economy, performance and passenger comfort. Careful analysis of cooling airflow, component placement and thermal shielding is required to avoid costly late-stage design fixes - or worse, failures in operation.
