A method for optimizing hydraulic fracturing simulates the geomechanical interaction between regional stress and natural fractures in a reservoir. An equivalent fracture model is created from data on the natural fracture density, regional stress and geomechanical properties of the reservoir, so that points in the reservoir are assigned a fracture length and fracture orientation. The horizontal differential stress and maximum principal stress direction at points in the reservoir are then estimated by meshless particle-based geomechanical simulation using the equivalent fracture model as an input. The meshless particle-based geomechanical simulator uses the derived initial geomechanical condition to simulate the sequence of hydraulic fracturing and derive the resulting strain and J integral that can be used to estimate the asymmetric half fracture lengths and initial propped permeability needed by hydraulic fracturing design and reservoir simulation software to optimize wellbore and completion stage positions.

Neural Network Loadflow (NNL) computation method is invented involving input vector composed of net nodal injection of real and reactive powers and diagonal elements of conductance and susceptance matrices multiplied by the squared voltage magnitude components of the flat-start normally used as initial solution estimate guess for loadflow solution by conventional NRL or SSDL methods. Training, and testing / validating input-output data sets are generated by applying uniform and non-uniform scaling factors applied to base case loads at PQ-nodes, resistance and reactance of transmission line branches. These scale factors are increased until loadflow solution by conventional methods such as Newton-Raphson Loadflow and Super Super Decoupled Loadflow methods diverge. Divergence of loadflow methods are due to node voltage, node angle, and numerical instabilities. Voltage magnitude and phase angle values in the solution before divergence are respective stability limits and voltage magnitude and phase angle values in loadflow solution provide direct measure to the respective stability margins. Also Suresh's diakoptiks based feature selection technique is presented for ANNs calculating one node variable with one neuron each in their output layers.

A method for optimizing hydraulic fracturing and refracturing simulates the geomechanical interaction between regional stress and natural fractures in a reservoir. An equivalent fracture model is created from data on the natural fracture density, regional stress and elastic properties of the reservoir, so that points in the reservoir are assigned a fracture length and fracture orientation. The horizontal differential stress and maximum principal stress direction at points in the reservoir are then estimated by meshless particle-based geomechanical simulation using the equivalent fracture model as an input. Regions in the reservoir having low differential stress based on the simulation can then be selected for initial hydraulic fracturing. Regions in the reservoir having high differential stress based on the simulation can then be selected for refracturing.

The technique of the invention sets a control start revolution speed Nstart to decrease with an increase in driver's power demand P* and with an increase in vehicle speed V (step S130), and motors an engine (steps S150 to S190). When a revolution speed Ne of the engine reaches the setting of the control start revolution speed Nstart, operation control of the engine starts (step S220). Such settings are ascribed to the following reasons. Setting a relatively small value to the control start revolution speed Nstart is preferable to trigger an early start of operation control of the engine and ensure quick output of power from the engine. In order to ensure reduction of vibrations of initial explosion and resulting reduction of potential vibrations arising at the time of starting the engine, on the other hand, setting a relatively large value to the control start revolution speed Nstart is preferable. The driver's sensitivity to the vibrations is lowered with an increase in vehicle speed V.
