Temporary Deployment of Multiphase Flow Measurement to provide Well Performance Data: A Case Study

摘要

This paper details the preparation and temporary deploymentrnof a Multiphase Flow Meter (MPFM) for a series of multi-raternwell tests carried out on high gas-liquid ratio (GLR)rnproduction wells.rnThe MPFM incorporated specific design features to permitrnaccurate measurement of liquid rates in high Gas VoidrnFraction (GVF) production streams and was prepared as a skidrnmounted unit for ease of deployment, hook-up andrndemobilisation.rnMPFMing was chosen in order to eliminate the need to flare orrnrecompress depressurised fluids. This permitted the wells to bernflowed at flowrates similar to their normal production rates,rnwhich maximised the benefit of the data obtained, without thernneed to deploy expensive and space consuming additionalrnequipment.rnThe ease and speed of deployment and hook-up demonstratesrnthat such equipment can provide well performance datarnsimilar to that collected by a conventional temporary well testrnspread.rnCumulative well performance curves generated from the datarncollected showed good correlation with production station datarnsupporting previous conclusions regarding the accuracy ofrnMPFM’s. The maintenance of this accuracy in the difficultrnhigh GVF flow regime vindicates the use of the particularrnequipment model and design chosen.rnThe small footprint, reduced crew size, and elimination ofrnflaring makes this system an attractive option for testing onrnunmanned facilities, in environmentally sensitive areas andrnwhen space constraints appear prohibitive.
