Widely used to look for fractures and discontinuities, and thus useful in any resource play, attributes including curvature, phase congruency and energy ratio can be computed from stacked seismic volumes. The Attributes package is a collection of advanced, multi-trace (spatial) attributes that can be derived from seismic volumes. These properties are increasingly supplied as an end-product to reservoir engineers for optimizing well placement in shale plays. Embedded in the seismic utilities module, these tools calculate volumes of properties such as Young’s Modulus, Brittleness and Closure Stress Ratio from pre-stack inversion results. HRS-9 now includes ready-made tools for computing volumes of geomechanical properties, of particular benefit for well and completion planning in resource plays. Geomechanical properties through the entire seismic volume In a subsequent release later in 2014, Hampson-Russell will add the ability to extract sampled attributes from seismic volumes along horizontal well paths. This functionality is vital for the many horizontal wells that are typical of shale and steam-assisted gravity drainage (SAGD) projects. Horizontal well plotting on seismic sectionsĪny well log attribute for horizontal wells can now be overlaid on seismic volumes and displayed as a log curve or colour infill. ProMC now includes an interactive graph of Vp/Vs ratios which is displayed while picking horizons on PS volumes so that the interpreter receives instant interactive feedback on whether or not the PS horizon picking is correct for faster and more accurate interpretation.įurther refinement to the joint inversion of PP and PS volumes is provided through a new option for an automatically computed, variable Vs/Vp ratio (Gamma). Multi-component interpretation involves identifying key geologic markers on the PP wave and PS wave datasets but deciding which PS horizons match individual PP horizons can be challenging.

It also analyzes azimuthal variations in AVO amplitudes to infer the intensity and orientation of natural fracture swarms.įast and accurate multicomponent interpretation ProAZ can generate common-offset/common-azimuth and common-angle/common-azimuth gathers. It builds on HRS-9, launched in 2012, by offering geoscientists new capabilities focusing on unconventional resources.Īzimuthal AVO for fracture identificationĪ completely new module named ProAZ will increase the effectiveness of well planning in fractured reservoirs and unconventional resource plays by helping interpreters map fractures and other forms of anisotropy. CGG has released HRS-9/R2, an upgrade to its intuitive and interactive Hampson-Russell HRS-9 reservoir characterization software suite.
