A method of integrated modeling using multiple subsurface models includes receiving multiple sets of input values associated with a hydrocarbon formation of the Earth. The method also includes receiving a network model that includes one or more assets configured to distribute a flow of hydrocarbons from the hydrocarbon formation to a processing facility. The method further includes generating the multiple subsurface models based on the multiple sets of input values, wherein each subsurface model comprises a set of input values of the multiple sets of input values, and wherein each subsurface model represents a production of the flow of hydrocarbons from the hydrocarbon formation. The method also includes applying the multiple subsurface models to the network model to generate an integrated model comprising multiple production rates of hydrocarbons via the one or more assets over time. The method further includes identifying at least one asset to adjust based on the integrated model.

The invention relates to a method for exploiting a geological reservoir which may be a reservoir storing gas (for example CO.sub.2). The exploitation (EX) of the geological reservoir is carried out according to an exploitation scheme (SE) defined on the basis of a reservoir model (MR) with the reservoir model being matched (CAL) in relation to dynamic data (DD). According to the invention, the reservoir model (MR) is made representative by a multiple-scale parameterization, with at least two reservoir models (MR1, MR2) that have a different number of mesh cells.

An aspect of combining simulation models includes a processor configured to process information relating to a plurality of simulated models. The processor collects the information to be processed related to the simulated models in at least one memory having metadata relating to the simulated models. The processor has a transformation component generated using a schema mapping tool. The transformation component detects and corrects any incompatibility between a first and a second simulation model by obtaining metadata relating to the first simulation model and the second simulation model from the memory.

System and methods for performing look-ahead and look-around (LALA) inversion are provided. Measurements of formation properties accumulated by a downhole LALA tool are obtained during different stages of drilling a wellbore through layers of an underground formation. A distribution of formation properties measured for the layers behind a current layer is determined. A formation model for look-ahead inversion is defined based on the determined distribution of formation properties behind the current layer. Measurements of the current layer's formation properties collected by the downhole LALA tool are obtained. A distribution of formation properties for one or more layers ahead of the current layer is estimated based on the formation model and the measurements of formation properties obtained for the current layer. The estimated distribution includes a gradient transition of formation properties between the current layer and the one or more layers ahead of the current layer.

A method for developing a virtual testing model of a subject for use in simulated aerodynamic testing comprises providing a computer generated generic 3D mesh of the subject, identifying a dimension of the subject and at least one reference point on the subject, imaging the subject to develop point cloud data representing at least the subject's outer surface and adapting the generic 3D mesh to the subject. The generic 3D mesh is adapted by modifying it to have a corresponding dimension and at least one corresponding reference point, and applying at least a portion of the point cloud data from the imaged subject's outer surface at selected locations to scale the generic 3D mesh to correspond to the subject, thereby developing the virtual testing model specific to the subject.

Methods are provided for: (i) measuring the position of the blade stagger angle axis for one or more blades of a row of blades attached to a rotor, (ii) measuring the blade tip stagger angle for one or more such blades, and (iii) measuring the blade tip axial displacement for one or more such blades. The methods use forward and rearward blade tip timing datasets for successive rotations of the blades from two axially spaced blade tip timing probes. The forward probe is forward of the rearward probe along the axial direction of the rotor. The blade tip timing datasets allow the times of arrival of the blades at the respective probes to be measured. The methods also use a once per revolution dataset for the successive rotations of the blades. The once per revolution dataset allows the angular velocity of the blades to be measured.
