This is achieved by introducing a design-time object modeling construct called a dynamically configurable type (DCT) that supports the subdivision of an object into a plurality of subsets of semantics and allows dynamic merging of these semantic subsets together in different combinations in order to allow the resultant object to exhibit different semantics over time to serve different purposes.

A model system for simulating the performance of a subterranean well, starts with a base model wherein input logging data, pressure transient data and PVT data is introduced into the base model. A numerical interpreter then calculates the predicted performance of the well. A match system compares actual performance data with calculated performance data based on the base model through reiterative loop for modifying the base model to provide a match between the actual performance data and the predicted performance data to optimize the base model.

Methods and systems for integrating process perspectives and abstraction levels into business process modeling are described. In one example embodiment, modeling business processes for an enterprise can include selecting a segmented view of an enterprise meta-model.

A business process model is created using a set of visual modeling tools, which are limited by the segmented view. A business policy having some relevance to the process being modeled can be selected for annotation to the business process. Once completed, the business process model is transformed into a machine-readable representation and stored in a repository.

A computer implemented method for modeling of faulting and fracturing uses “small scale rules” to produce large-scale results. One part of the method is a user interface for inputting deformations, preexisting faults and fractures, and material rock properties. The second part of the software is the code that solves the motion of each point or node in the subsurface volume defined by the user interface. The model may be defined in one of three modes: an aerial mode, in which the model is 2-dimensional with the material and a substrate on a horizontal plane; a cross-sectional mode similar to the aerial mode except that the nodes are in a vertical cross section and gravity is included in the model; and a 3-D model that is an extension into a third dimension of the 2-D model and deformation may be applied to the bottom and four sides of the material region.A modified over-relaxation approach, wherein the over-relaxation is concentrated in those nodes where the greatest movement occurs, is used to solve for the deformation. This significantly speeds up the computation time. The model is “conditioned” to increase the likelihood that the deformation pattern resulting from the simulation of the deformation will at least duplicate an observed large-scale deformation. As an aid to the simulation, an “anticipate” step provides a quick solution to the deformation without including the effects of faulting.
