SEISMIC PETROPHYSICS Rock Physics Modeling Prediction away from wells Seismic Rock Physics, LLC. COURSES 6 5360 5380 In different areas, seismic may show different type of amplitude anomalies. These anomalies are caused by local changes in rock properties. The investigation of what causes these anomalies is important because it can prove hydrocarbon source, reservoir presence, and trap. However, similar-looking anomalies can also be caused not only by the presence of hydrocarbon, but also by changes in lithology or thickness. We build Taylor- made QI workflows to solve specific problems. Our workflows may include: ▪ Well-log conditioning for rock physics analysis and seismic inversion ▪ Estimation of Shear wave velocity and density from P-wave velocity based on lithology and rock microstructures. ▪ Upscaling of well-log data to seismic data ▪ Depth trends analysis ▪ Seismic Rock Physics to parameterize acoustic and simultaneous elastic inversion ▪ Extended Elastic Impedance analysis ▪ Wedge modeling using horizontal and slanted layers ▪ Full waveform synthetic seismograms for isotropic and anisotropic media ▪ AVO analysis for probable geologic scenarios in the well and away from the well ✓ What reservoir properties can be discovered using measured seismic amplitudes? ✓ How can we estimate rock properties from seismic amplitudes and travel times? The following is a list of possible geological features that affect rock elastic properties significantly. ✓ Fractures ✓ Mineralogy and TOC ✓ Porosity ✓ Rock Microstructure ✓ Textural features: Sorting, cementation, grain, and pore size and shape) ✓ Fluid type ✓ Fluid volumes ✓ Fluid distribution in pore space ✓ Fluid properties ✓ Salinity ✓ Brittleness ✓ Stresses ✓ Pore Pressure ✓ Temperature Depth (m) Y (m) X (m) 2000 PR 0.1 0.2 0.3 0.4 6 12 18 Poisson ratio Ip (km/s g/cc) 0.1 0.2 0.3 0.4 4 8 12 Poisson ratio Is (km/s g/cc ) 2.4 2.6 2.8 6 12 18 Density (g/cc) Ip (km/s g/cc ) Ip (km/s g/cc) These courses are uniquely designed comprehensive state-of-the-art instructions in rock physics and seismic petrophysics. These courses will equip you with the necessary tools to start applying rock physics. They are intended for Geologists, Geophysicists, Petrophysicists, and Engineers to provide grounding in understanding relationships between geophysical measurements and rock properties, with emphasis on the integrated interpretation of seismic, well logs, and laboratory data. They are not exclusively a theoretical courses, but orientation on the necessary theories will be provided. ✓ Rock Physics Fundamentals ✓ Fluid Substitution ✓ Seismic Petrophysics ✓ Static/Dynamic Mechanical Properties ✓ Pore Pressure and Fracture Gradient

Seismic Rock Physics LLC. is an oil-servicecompany based in Texas, USA.Rock Physics helps E&P companies to de-riskprospects and analyze uncertainties inresource estimation during seismicinterpretation. The understanding of therelationships between rock properties andseismic signature help to define if thediscrimination of reservoir properties can beachieved using only amplitude with offsetanalysis or also a specific kind of seismicinversion technique.

The activities related to rock physics studiesinclude different tasks, depending on thegoal of the project. They usually comprise theintegration of laboratory, well, and seismicdata. The purpose of rock physics is to betterunderstand the seismic response of targetreservoirs and of the overlying andunderlying formations. Based on a rockphysics feasibility study, in one or severalwells, we should be able to define whichseismic attribute or inversion method areoptimal for: the characterization of targetformations, identification of shallow hazards,pore pressure prediction, and estimation ofmechanical properties for geomechanics.
