Welcome from all of us

CREWES Overview Advanced research and education in geophysical exploration in partnership with the resource industry Specifically, to develop multicomponent seismic methods to image and monitor the subsurface and its fluids

The University’s Multicomponent Mandate The 3C’s: to create, communicate and conserve knowledge possibly 4C: to commercialize

People & Funding 7 faculty investigators, 12 research geophysicists and support staff 40 graduate students CREWES group budget (2003): $1,400,000/year 27 industrial sponsors @ $35k/yr NSERC (Gov’t of Canada) support $450,000/year Other research funding: $200,000/yr

CREWES Strategy 3D reservoirs – ultimately need 3D analysis P-wave imaging is usually best (fast, sharpened, in depth, and anisotropic) P-S analysis for lithology & imaging special cases Integrate VSP, well logs, & rock physics Research where there’s need & opportunity Plan, acquire, process, & interpret real data

SEISMIC LITHOLOGY & FLUID IMAGING CREWES Focus SEISMIC LITHOLOGY & FLUID IMAGING FIELD OPS. & INSTRUMENTS PHYSICAL MODELING NUMERICAL MODELING BOREHOLE & HIGH-RES. SIGNAL PROCESSING INTERPRET. & CASES

CREWES Special Interest Plains (Blackfoot, Red Deer, Swift Current – lithology, coal-bed methane, inversion) Heavy Oil (Cold Lake, Pikes Peak, Jackfish) – shallow imaging, lithology, thermal monitoring Arctic (Mackenzie Delta, Devon Island) – permafrost, methane hydrates, fixed/floating ice Marine 4-C (White Rose, Sable, GoM, N. Sea) – OBC/S technology, reverb/multiples Structural areas (Copithorne)

Challenges & Research Areas from CREWES survey 2002 3 3C VSP analysis 3 Decon / phase for PS 3 PS Statics 3 Sub-gas imaging 4 Velocity model building 5 PP and PS Correlation/Interpretation 5 Joint Vp, Vs, ρ estimation (inversion) 5 Depth imaging (2D & 3D) 5 Multiple removal (PZ, 4-C)

6 Receiver (and source) vector fidelity 8 Q estimation & filtering increased resolution in PP & PS for lithology and fluids 8 Anisotropy analysis (VTI, azimuthal, γ) Fracture characterization
