FLAC, FLAC3D, & UDEC for Geomechanics & Reservoir Engineering

The main objective of this course is demonstrating the implementation of numerical modeling and geomechanics simulation in reservoir engineering. The course focuses on the practical applications of numerical modeling for simulation and analysis of geomechanics problems such as wellbore stability, geothermal analysis, flow analysis, and hydraulic fracturing.

Course Outline

Several topics including elasticity and plasticity of the rock medium, constitutive models, stress distribution, and permeability considerations will be discussed. The simulation procedure of isotropic and transversely isotropic medium and faults and discontinuities will be presented. Commercial programs for geomechanics modeling will be introduced, and finite difference, finite element, and distinct element methods for numerical modeling will be described. Different software tools including FLAC, FLAC3D, and UDEC will be considered for conducting simulations.

Topics covered include:

• Introduction to numerical modeling in geomechanics
• Introduction to finite element, finite difference, and distinct element modeling using FLAC, FLAC3D, UDEC, and 3DEC
• Constitutive models used for conventional and unconventional reservoirs
• Practical application of two-dimensional stress/strain wellbore stability analysis using FLAC
• Practical application of three-dimensional stress/strain wellbore stability analysis using FLAC3D
• Three-dimensional modeling and analysis of inclined wellbores using FLAC3D
• Wellbore stability analysis under drilling mud pressure using FLAC
• Flow analysis and permeability considerations
• Practical application of hydraulic fracturing and fluid injection into porous medium using UDEC
• Discontinuity and faults modeling in underground reservoirs
• Geothermal analysis of underground reservoirs using FLAC

Testimonials

Bela S., Reservoir Engineer, Germany

"It was really helpful to learn about the usage of the widely used numerical software packages in the industry and how they can handle praxis-oriented geomechanical problems on a theoretical basis."
