1. A method, comprising:
shutting in a well and connecting a pressure control system and a tool body to an adapted tubing hanger plug;
installing the pressure control system, the tool body, and the adapted tubing hanger plug into a borehole;
opening the borehole for a fluid flow;
measuring a first flow rate of the fluid flow with a spinner;
generating one or more temperature spikes using a thermal generator;
measuring a time for the one or more temperature spikes to travel from the thermal generator to a temperature probe;
calculating a second flow rate of the fluid flow based, at least in part, on the time;
measuring one or more physical properties of the fluid flow with one or more sensors disposed within an electronics section of the tool body;
closing a surface safety valve and a subsurface safety valve;
retrieving the adapted tubing hanger plug and the tool body from the borehole; and
downloading data for analysis of the first flow rate, the second flow rate, and the one or more physical properties.
