Abstract

Claims (35)

1. A method for well testing using a tubing hanger deployed apparatus, comprising:

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 outside a borehole and installing the tool string and the adapted tubing hanger plug into the borehole;

opening the borehole for a fluid flow;

measuring a flow rate of the fluid flow through the borehole using a flowmeter;

measuring physical properties of the fluid flow with sensors on the tool string;

closing a surface safety valve;

retrieving the tool string; and

downloading data for analysis of the flow rate and physical properties measured.

2. The method of claim 1 , wherein the physical properties measured are a pressure, a temperature, a density, and a fluid phase of the fluid flow.

3. The method of claim 2 , wherein the density of the fluid flow is used to determine a water cut.

4. The method of claim 1 , wherein a truck-mounted crane is used to lower the tool string into the borehole.

5. The method of claim 1 , wherein the flowmeter comprises a fullbore spinner and an inline spinner.

6. The method of claim 1 , wherein the adapted tubing hanger plug has a centralized hole to allow full flow with a perforated joint.

7. The method of claim 1 , wherein a calibration is performed to determine an average velocity of the fluid flow.

8. The method of claim 1 , further comprising extracting the adapted tubing hanger plug and the tool string from the borehole.

9. A system for a tubing hanger deployed apparatus, comprising:

an adapted tubing hanger plug configured to allow full flow through of fluids from a borehole to a surface;

a flowmeter configured to measure a flow rate of a fluid in the borehole;

a pressure control system configured to prevent an uncontrolled flow of liquids from the borehole;

a tool string configured to carry sensors into the borehole;

a plurality of sensors configured to measure pressure data, temperature data, fluid density data, and fluid phase data;

a memory section configured to record the pressure data, the temperature data, the fluid density data, and the fluid phase data; and

an electronics section configured to control sensor measurement and recording operations,

wherein the electronics section is configured to determine a water cut based on the fluid density data.

10. The system of claim 9 , wherein the flowmeter comprises a fullbore spinner and an inline spinner.

11. The system of claim 9 , wherein the sensors comprise a pressure sensor, a temperature sensor, a density sensor, and a fluid phase sensor.

12. The system of claim 9 , wherein a truck-mounted crane is used to lower the tool string into a borehole.

13. The system of claim 9 , further comprising a wireless communication system between a surface facility and the memory section.

14. The system of claim 9 , wherein a battery pack supplies power to the sensors.

15. The system of claim 9 , wherein the adapted tubing hanger plug is a standard plug adapted to allow a fluid flow through the standard plug.

16. The system of claim 9 , wherein the flowmeter is calibrated outside a borehole.

17. The system of claim 9 , wherein the adapted tubing hanger plug has a centralized hole to allow a fluid flow with a perforated joint connected below the adapted tubing hanger plug and above the tool string.

18. The system of claim 9 , further comprising a winch, wherein the winch at the surface may generate mechanical power and transmit power and communications to the tubing hanger deployed apparatus through a wireline.

19. The system of claim 9 , further comprising a programmable controller to control the sensors.
