Introducing CMMI Measurement and Analysis Practices into Scrum-based Software Development Process

Abstract

The McMurray Formation of northern Alberta in Canada con- tains multiscale complex geologic features that were partially formed in a fluvial-estuarine depositional environment. The in- clined heterolithic strata deposited as part of fluvial point bars contain continuous centimeter-scale features that are important for flow characterization of steam-assisted gravity drainage pro- cesses. These channels are common, extensive, and imbricated over many square kilometers. Modeling the detailed facies in such depositional systems requires a methodology that reflects heterogeneity over many scales. This article presents an object- based facies modeling technique that (1) reproduces the ge- ometry of multiscale geologic architectural elements seen in theMcMurray Formation outcrops and (2) provides a grid-free framework that models these geologic objects without relating themto a grid system.The grid-free object-basedmodeling can be applied to any depositional environment and allows for the completepreservation of architectural information for consistent application to any gridding scheme, local grid refinements, downscaling, upscaling, drape surface, locally variable azimuths, property trend modeling, and flexible model interaction and manipulation. Features millimeters thick or kilometers in extent are represented very efficiently in the same model.
