Hampson-Russell has been providing innovative geophysical software since ? 1987. ? AFI (AVO Fluid Inversion) * estimates the uncertainty in the fluid predictions from AVO. We designed the program as a seamless add-on to the AVO program. AFI uses Biot-Gassmann fluid substitution, Monte Carlo simulation and Bayesian estimation to build fluid probability maps. You then use these maps to make a quantitative analysis of the probability of exploration success. AVO - Analysis & Modeling * AVO analyzes the fluid content of reservoir rocks through a combination of visual, analytical and modeling processes using both pre-stack seismic and well log data. AVO is started by Geoview and can use the View3D application to view its attribute maps. EMERGE * EMERGE predicts reservoir properties using seismic attributes and well log data. The seismic attributes can either be internally or externally derived, and the target can be any measured or calculated log such as porosity, density or water saturation. Typical external seismic attributes are inversion results from STRATA or AVO attribute volumes ISMAP * ISMAP is a mapping tool that statistically compares and analyzes mapped data. Typical data inputs are a combination of dense, 'fuzzy' data such as seismic attribute maps, and sparse, accurate data such as well log values. PRO4D * PRO4D provides a framework to analyze and interpret time-lapse datasets. Time-lapse, or 4D seismic monitoring, relies on the comparison of 3D surveys that are recorded at different phases of the production process. In many cases, changes in the seismic response can show production-induced changes in the fluid saturation, pressure or temperature in the reservoir rocks. PROMC * PROMC is a software package designed to make multi-component interpretation and modeling highly accessible. Conventional P wave seismic data responds to changes in lithology and fluid content, while Shear wave data is largely insensitive to fluid changes. This means a combination of P and S wave data can provide additional information and reduce uncertainty in lithology prediction by separating lithology from fluid responses. However, we must correlate the P and S wave data prior to interpretation and this is often a difficult process. STRATA * STRATA is a program used to perform both post-stack and pre-stack seismic inversion. In the classic post-stack domain, STRATA analyzes 2D or 3D post-stack seismic volumes to produce an acoustic impedance volume. In the pre-stack domain, STRATA analyzes angle gathers or angle stacks to produce volumes of acoustic impedance, shear impedance and density.
