Overview
Get a detailed representation of your reservoir's structure, stratigraphy, and rock properties with 3D static geomechanical modeling from GaffneyCline™ energy advisory.
Our modeling experts combine 1D geomechanical models with 3D structural data and other information to build a detailed 3D geomechanical model of your field.
As a first stage, the 3D static geomechanical model will be based on 3D structural grids, maps, and logs in line with the structural models. Our systematic approach to building your model includes:
- Using statistical techniques such as inverse distance interpolation, kriging, or Gaussian simulations to interpolate and extrapolate geomechanical properties from 1D models into a 3D space.
- Leveraging seismic interval velocities and well-log data to populate the structural grid with physical and mechanical properties such as density, velocity, porosity, Young’s modulus, and Poisson’s ratio.
- Including faults in the structural model to create a realistic geometry that is consistent with reservoir simulation geometry.
- Calculating horizontal stresses within the 3D structural grid based on the local pore pressure and overburden values in combination with modeled absolute or effective stress ratios.
- Using the properties in the populated 3D structural model to construct the 3D geomechanical model using transforms derived for the 1D models.
The result is a 3D static geomechanical model with realistic lateral and vertical variations in mechanical properties and, where applicable, stresses and pore pressures. This model will serve as a valuable geomechanical analysis tool in applications where standard stretching techniques do not apply.
