Systems and a method for well testing using a tubing hanger deployed apparatus are disclosed. The method includes shutting in a well and connecting a pressure control system and a tool string to an adapted tubing hanger plug; installing the pressure control system, the tool string, and the adapted tubing hanger plug into a borehole; opening the borehole for a fluid flow; measuring a flow rate of the fluid flow through the borehole using a flowmeter; and measuring physical properties of the fluid flow with sensors on the tool string. The method further includes closing a surface safety valve and optionally closing a subsurface safety valve; retrieving the adapted tubing hanger plug and the tool string; and downloading data for analysis of the flow rate and physical properties measured.

Well testing method using tubing hanger deployed apparatus

A method includes shutting in a well and connecting a pressure control system and a tool body to an adapted tubing hanger plug. The pressure control system, tool body, and adapted tubing hanger plug are installed into a borehole, which is then opened for fluid flow. A flow rate of the fluid flow is measured with a spinner. Temperature spikes are generated using a thermal generator, and a time for the temperature spikes to travel from the thermal generator to a temperature probe is measured. A flow rate of the fluid flow is calculated based on the time. Further, physical properties of the fluid flow are measured with sensors disposed within an electronics section of the tool body. Surface and subsurface safety valves are closed, and the adapted tubing hanger plug and the tool body are retrieved from the borehole. Data is downloaded for analysis.

Actual distributed temperature sensing (DTS) data and pressure data are received in response to a stimulation treatment applied to a hydrocarbon field. A pre-stimulation model is built that includes reservoir parameters, which generates simulated DTS and pressure data as a function of the reservoir parameters that include a permeability parameter and a skin parameter. In response to determining that a thermal match between the actual DTS and pressure data and the simulated DTS and pressure data is not obtained, the reservoir parameters are updated. In response to determining that the updated reservoir parameters do not match a performed pressure transient analysis (PTA), the reservoir parameters and the pre-stimulation model are updated, and the simulated DTS and pressure data are re-generated based on the updated pre-stimulation model.
