Abstract:
© 2020 Elsevier Ltd Field testing data from five different wells using load cell sensors were analysed to investigate their possible application for estimating geothermal two-phase fluid enthalpy. Two different data analysis approaches - measuring the liquid phase velocity and estimating the dryness fraction - were examined. The liquid velocity was predicted successfully using the cross-correlation technique. However, liquid velocity cannot be used alone to measure the fluid enthalpy without slip ratio and void fraction. It was only possible to calculate the dryness fraction estimate from the weight of the pipeline for one data set due to measurement noise and the results were found to be of low quality. The remaining technical challenges and recommendations are discussed.
