64 | Method for controlling the development of an oil or gas reservoir | EP98303548.6 | 1998-05-06 | EP0881357A3 | 2002-02-06 | Stephenson, Stanley V. |
Development of an oil or gas reservoir is controlled using a neural network and genetic algorithm program to define a neural network topology and the optimal inputs for that topology. The topology is defined from identified and selected parameters (1) associated with the formation or formations in which actual wells are drilled in the reservoir, and (2) associated with the drilling, completion and stimulation of those wells, and (3) associated with the oil or gas production from the wells. Subsequent drilling, completion and stimulation of the reservoir is determined and applied based on hypothetical alternatives input to the topology and resulting outputs. |

The invention concerns a sensor arrangement for controlling vehicle ventilation systems which recirculate or deliver air in dependence on the pollutant concentration in the air outside the vehicle. The sensor arrangement comprises a gas sensor element (52) whose electrical resistance decreases when reducing gases occur and increases when oxidizing gases occur. The arrangement further comprises an evaluation unit (51) whose output is connected to the ventilation system control device. In order to simplify the sensor technology of such a sensor arrangement and to configure the evaluation system such that it is less expensive, this sensor arrangement is designed so that the rise in a gas sensor signal input into the evaluation unit when the reducing gas concentration increases is quantitatively and approximately equal to the fall in the gas sensor signal input into the evaluation unit (51) when the oxidizing gas concentration correspondingly increases; so that the evaluation unit (51) determines from the gas sensor signal input thereinto the rise or fall in the gas sensor signal per unit of time; and so that the evaluation unit (51) generates a switching signal to change over the ventilation system to recirculation as soon as the determined rise or fall in the gas sensor signal per unit of time quantitatively exceeds a threshold value. | ||||||
