  5. Correlation of present day stress vector and faults (plate boundaries) Africa http://peterbird.name/publications/2006_South_Africa

  6. “Vector” correlation between anisotropy, a, and curvature c

  8. AASPI 2014 Workplan – Integrating Microseismic • Microseismic source characterization and correlation with stratigraphy/seismic attributes • Fault plane solutions Full moment tensors? • Quantifying value of multiple monitor wells • Error as a function of number of monitors and SNR • Effect of Double Difference locations vs. number of monitors and SNR • Uniqueness of VTI velocity models, we all know that the correct VTI model gives us better locations, but what about incorrect VTI models? • A new approach for attribute based ‘productivity maps’

  9. Productivity Productivity Relative Curvature Cutoff

  10. Emerging trends & Algorithm development • 3D Supervised Facies Classification (Tao Zhao, Atish Roy, V. Jayaram) • Applications : Sweet Spot Identification, • Generating Classification maps • EUR prediction & Mapping Production Data • Techniques Investigated : • Distance Metrics in GTM, SOM (Atish Roy) • Support Vector Machines (Tao Zhao) • Transformations or Blind Source SeparationTechniques (V. Jayaram) • Applications : Dimensionality Reduction & Cluster Analysis • Techniques Investigated : • Noise Adjusted Principal Components (Atish Roy) • Independent Component Analysis

  11. Emerging trends & Algorithm Development • Statistical Parameterization of Well Data (David Lubo, V. Jayaram) • Applications : Reservoir Characterization, • Correlating Well data to Seismic Attributes • Techniques Investigated : Gaussian Mixture Models (David Lubo) • Markov Models • Non-Linear Regressors (Melia da Silva, V. Jayaram) • Applications : Establishing quantitative relationships between • fracture intensity and curvature, • Correlating Production Data to Seismic Attributes • Techniques Investigated : Gaussian Mixture Regression • Kernel Regression • Texture Analysis (Marcus Cahoj, V. Jayaram) • Applications : Geology Interpretation, Fault Identification • Techniques Investigated : Gabor Energy Vs. GLCM

  12. Average fracture intensity vs. curvature Faulting Fracture saturation Fracture generation This is NOT a linear correlation Elastic deformation (White, 2013)
