FIGURE 2 Location of 3-D Survey Area and Permian Basin Geologic Setting data. Stage and completion information is used to define productive zones for integrating with the geoscience data. The initial step in integrating the geoscience and engineering data is to extract 70 THE AMERICAN OIL & GAS REPORTER 3-D seismic attributes along each wellbore at or near the stage locations using a statistical sampling method. Next, the extracted attributes are correlated with a range of production metrics, completion data and well data to determine the degree to which variables are correlated. This also allows the interpreter to understand the individual relationships each variable has with production and what type of transformation may be needed in the multivariate analysis. The goal for this stage is to leverage the integration, allowing the statistics to highlight the meaning of various relationships between production and seismic attributes. The result of multivariate analysis is to identify the KPIs and determine the optimal transformation required for each attribute. Finally, the KPIs are combined to create a 3-D seismically-calibrated predictive model and maps of production (or indeed any other response metric). Based on the input data available, the process also can determine engineering best practices, and can facilitate additional steps to validate the models. The integrated WPPA workflow can be repeated and the models can be carried forward throughout the life of a particular reservoir or field to identify ideal landing points for laterals and completion zones to optimize production.
