Abstract: Techniques are described for automatically generating a reporting model based on a relational database storing multidimensional data in accordance with a relational database schema. A model generator may, for example, produce a base reporting model from the database schema, and subsequently generate a user reporting model by importing the base reporting model. The model generator updates the user reporting model in response to modifications requested by a user, and maintains an activity log to record the modifications. The model generator regenerates the base reporting model and the user reporting model in the event the database schema changes, and reapplies the modifications from the activity log to the user reporting model to automatically update the user reporting model. The database schema may be a relational star schema as described herein.

Abstract: Methods and systems for automatically reporting delay incurred in a model is disclosed. The delay may be incurred in a part or in an entire portion of the model. Delay incurred in each component of the model is determined and reported to users before executing the model. The delay of each component of the model may be determined based on intrinsic information of the component. If the intrinsic information of the component does not provide information on the delay of the component, the component may be simulated to determine the delay of the components. The model may be automatically compensated for the delay. The delay is reported prior to the execution of the model, and compensated for without executing the model.

Abstract: Method for optimizing the development of an underground reservoir, wherein a geological model is updated using dynamic data and well tests. A reservoir model is constructed by performing a geological model scale change. Dynamic data are simulated from this reservoir model. Influence zones are identified within the geological model where the well tests induce a pressure variation during well testing. Well tests are then simulated for each influence zone. An objective function measuring the difference between the simulated data and the measured data is calculated. The geological model is then modified so as to reduce to the maximum the objective function using a geostatistical parametrizing technique. Finally, development of the underground reservoir is optimized by evaluating, by means of a flow simulator, the reservoir production for various production schemes. Application: notably oil reservoir development.

Abstract: The present invention provides a numerical analysis model data generating program, method, and system for generating numerical analysis model data, which is used for numerical analysis, on the basis of three-dimensional shape data of a structure that is an object of analysis. Three-dimensional shape data defining the structure is inputted. Holes included in the inputted three-dimensional shape data are extracted, and the size of each of the holes is calculated. If the size of a given hole is smaller than a predetermined size, the hole is filled. Thus, numerical analysis model data is generated. According to the present invention, when the numerical analysis model data is generated, a relatively small amount of analysis model data can be generated without adversely affecting the accuracy in numerical analysis.
