Abstract: The present invention concerns a method for predicting the time evolution of a parameter for a set of wells, the method comprising selecting one or more prediction algorithms from a catalog, building, for each well, a prediction model on the basis of the selected algorithm(s) and of input data relative to each well of the set, the prediction model of each well being built with the first prediction algorithm for which a conformity criterion is fulfilled considering an order of use of the selected algorithms, validating the prediction models built for each well, and prediction of the time evolution of the at least one parameter for a well on the basis of the validated prediction model obtained for said well and on the input data of said well.

Abstract: A method for evaluating an underground reservoir production scheme accounting for uncertainties is disclosed having applications, for example, to the development of petroleum reservoirs. Flow simulator input parameters characterizing the reservoir and the production scheme are selected. An approximate analytical model allowing the reservoir responses to be predicted is constructed. A desired degree of accuracy Dp is defined, this degree of accuracy Dp measuring the difference between the responses of the model and those of the simulator. The degree of accuracy Dp(M) of the predictions of the model is calculated. Simulations are selected which are performed, pertinent for adjustment of the model. The simulations are carried out for each response simulated by the simulator and the analytical model is adjusted by means of an approximation method.

Abstract: Method for evaluating an underground reservoir production scheme taking account of uncertainties. Flow simulator input parameters characterizing the reservoir and the production scheme are selected. An approximate analytical model allowing the reservoir responses to be predicted is constructed. A desired degree of accuracy Dp is defined, this degree of accuracy Dp measuring the difference between the responses of the model and those of the simulator. The degree of accuracy Dp(M) of the predictions of the model is calculated. A design of experiments is constructed so as to select simulations to be performed, pertinent for adjustment of the model. The simulations selected by the design of experiments are carried out, then, for each response simulated by the simulator, the analytical model is adjusted by means of an approximation method. This operation is repeated until the desired degree of accuracy Dp is reached.

Abstract: A latch mechanism secures a computer component to a chassis; the mechanism includes a base that is attached to the computer component, a latch handle pivotably mounted on the base, the latch handle being capable of pivoting away from the base. An actuator arm is pivotably mounted to the latch handle so that when the latch is pivoted away from the base, the actuator arm will also move away from the base. A cam plate is also pivotably mounted on the base and is capable of rotating with respect to the base. The cam plate includes at least one notch adapted to cooperate with the chassis so that as the cam plate is rotated, the notch selectively engages and disengages with the chassis.

Abstract: The present invention provides chassis for housing at least one processor, the chassis includes at least one compartment adapted to receive a processor, a connector for coupling the at least one processor to the chassis when the processor is installed in the at least one compartment. The connector includes a first component attached to the processor and a second component attached to the chassis and adapted to be mated with the first component, the connector may also be adapted to provide data and power connections between the chassis and the processor when coupled. Additionally, the first component aligns and mates with the second component during the insertion of the processor into the compartment without any visual alignment of the first and second components of the connector.
