Correlation of Flowmeter Velocity with Fluid Phase using the Flowing Survey Data of Well SK-2D

Abstract

With the aim of further evaluating the many beneyts that the electronic Temperature-Pressure- Spinner (TPS) logging tool can provide, this paper attempts to correlate the spinner responses fluid velocity) recorded with the phase of the jluid during a TPS survey of a discharging well. TPS data of well SK-2D in the Mindanaol Geothernial Project, Philippines was used in this study.

Wellbore simulation wns performed in SI(-2D to determine the fluid phase while discharging at dvferent well openings, The wellbore simulator used can only handle single feed zone which is located at the bottoni of the wellbore. Since SK-ZD is a niulti-feed well, a simulation procedure is proposed that accounts for the different production zones observed using the single feed wellbore simulator. With this method, a good match of the flowing temperature and pressure data, the massflow and enthalpy data was obtained. The simulation results (Le. dryness, velocity, enthalpy, and density) were then correlated with the recorded spinner responses. Finally, a procedure for correlating the spinner responses with the fluid phase is suggested.
