| Summary: | The crude oil component fractions consists of oil, gas and water. The oil and gas industry
requires an efficient technology that ensure that oil produced meet the standard
requirement and the market needs. Therefore, it is vital to classify the oil according to its
flow regime. Crude oil is transferred from offshore to onshore using pipes. ECT system is
applied to measure the capacitance value inside the pipe. The capacitance value
measurement represents the permittivity distribution of the oil flow. The capacitance data
generated from the ECT system will be classified according to the flow regime. In order to
enable the simulated ECT data to be classified, Artificial Neural Network (ANN) is
implemented. MLP Neural network and the Levenberg Marquardt algorithm is
implemented to create a desirable network. The simulated ECT data is divided into three
groups namely, training data, validation data and testing data. These data will be used to
train the MLP in order to get an optimum network. The best trained MLP is chosen based
on its “intelligence” in classifying unseen data correctly. Two factors investigated in
choosing the best network are the number of hidden neurons used and the size of training
data. These two factors will determine whether the network has reached its optimum
“intelligence” and has the potential to classify the oil according to its flow regime. |
