  2. AASPI 2012 Workplan: Multiplatform software deployment (Linux and Windows7)

  3. AASPI 2012 Workplan • Image processing/algorithm development • Continued development/calibration of azimuthal intensity algorithm • Incorporation of LUM and other robust statistics into sof3d, sof_prestack, and image_filt3d • Q estimation from phase component of spectral decomposition • Introduction of supervision into SOM and GTM – Atish Roy • Dip-sensitive spectral decomposition • Spectral balancing across offset and azimuth volumes • 2D histogram and interactive painting – Toan Dao • 3D color display or graphical rendering of curvature intensity, strike and normal to plane • Implement flexure attribute as roughed out by Dengliang Gao

  4. 2-D Manifold through the n-D data 2D Reference Map Maximize the likelihood that the data fit the model

  5. GTM clustering

  6. AASPI 2012 Workplan • Calibration to Geological Control • Mississippi Lime, Woodford Shale: correlation of attributes to fractures using outcrops and horizontal image logs – Trey White, Nabanita Gupta • More clay models and curvature calibration – Debu Paul, Trey White • Mississippi Lime/Tripolite: Correlation of attributes and elastic inversion to porosity seen in core and image logs – Ben Dowdell • Vera Cruz, Mexico: correlation of attributes and elastic inversion to depositional environment, fractures, and porosity – Araceli Romero • Barnett Shale, Fort Worth Basin: Correlation of elastic inversion to shale facies before and after hydraulic fracturing – Roderick Perez

  7. AASPI 2012 Workplan • Calibration to Production Data • Mississippi Lime – high water production in Osage Co., Geochem footprint and fractures between Mississippi Lime and Arbuckle? – Trey White and Sarah • Barnett Shale, Fort Worth Basin: Correlation of production logs in horizontal wells to surface attributes – John Henry Alcazate • Diamond M, Permian Basin: Correlation of production to seismic attributes – Oswaldo Davogustto • Correlation of EUR to proximity of karst and fractures; Correlation of EUR to macroscopic attribute ‘fabric’ – Alfredo Fernandez • Correlate EUR to anisotropic intensity, λρ-μρ, curvature, etc. via neural networks (dGB software) – Meliada Silva • λρ-μρ mapping of fractured rock and bypassed pay; measurement of spectral changes between reflection from and transmission through fractured rock - Roderick Perez

  8. Correlation of production (EUR) to proximity to karsts, lineaments, “textures”

  9. AASPI 2012 Workplan • Seismic Processing Algorithm Development • Detailed interval velocity analysis for resource plays – Bo Zhang • Detailed interval velocity analysis to preserve long-offset data for improved λρ-μρ, ρ, and anisotropic measures sensitive to TOC – Bo Zhang • 2C by 2C prestack time migration will Alford rotation: Diamond M , Permian Basin – OswaldoDavagustto • Diffraction imaging – Shiguang Guo • Necessary utilities including Swan-type residual moveout, high-res Radon, etc. – Kurt Marfurt and Tim Kwiatkowski

  10. AASPI 2012 Workplan: High resolution velocity analysis for interpretation and prestack data conditioning Migrated gathers Original migration velocities Preconditioned gathers sof_prestack NMO_reverse Migrated gathers with moveout Non-stretched gathers NMO_mp (non crossing) FCA_velocity Detailed velocities Vint “attribute” (every sample) VRMS_to_Vint (Simplex?) Isotropic Picking Anisotropic Picking

  11. AASPI 2012 Workplan Constrained least-squares migration for anisotropy improved fracture imaging Time-processed shot gathers Migration velocities Diffraction image? Demigrated shot gathers CLSM with (1-cosθ) obliquity factor CLSM with cosθ obliquity factor Migrated gathers Dip and azimuth • cosθ stack dip3d
