Abstract

A method for determining an amount of a liquid energy commodity stored in a tank comprises the steps of: receiving, at a central processing facility, volume capacity information associated with the tank and storing the volume capacity information in a database; receiving, at the central processing facility, one or more images of the tank; analyzing the one or more images of the tank to determine a liquid level for the tank; calculating the amount of the liquid energy commodity in the tank based on the determined liquid level and the volume capacity information retrieved from the database; and communicating information about the amount of the liquid energy commodity in the tank to a third-party market participant.

8. A method for determining an amount of a liquid energy commodity stored in a tank with an external floating roof, comprising the steps of:

receiving, at a central processing facility, volume capacity information associated with the tank and storing the volume capacity information in a database;

receiving, at the central processing facility, one or more images of the tank;

analyzing the one or more images of the tank to determine a liquid level for the tank, including a determination of a height of the external floating roof of the tank relative to a top of the tank;

communicating information about the amount of the liquid energy commodity in the tank to a third-party market participant.

9. The method as recited in claim 8, wherein the determination of the height of the roof of the tank relative to the top of the tank includes modeling the top, the roof, and a base of the tank as parallel elliptical planes.

10. The method as recited in claim 8, wherein the tank has an arm that extends between the roof and a wall of the tank, and wherein the determination of the height of the roof of the tank relative to the top of the tank includes measuring an angle of inclination of the arm.

11. The method as recited in claim 8, wherein the determination of the height of the roof of the tank relative to the top of the tank includes an analysis of one or more shadows generated by the tank.

21. The method as recited in claim 8, in which the images include photographic images, infrared images, or both photographic images and infrared images.

22. The method as recited in claim 8, in which the liquid energy commodity is selected from the group consisting of crude oil, natural gas liquid derivatives, and refined petroleum products.

28. The method as recited in claim 8, wherein the one or more images of each tank are received from a satellite imaging system.

12. A method for determining an amount of a liquid energy commodity stored in a tank with a fixed roof, comprising the steps of:

periodically conducting an inspection of the tank from a remote vantage point and without direct access to the tank, including collecting one or more images of the tank;

receiving, at a central processing facility, volume capacity information associated with the tank and storing the volume capacity information in a database;

receiving, at the central processing facility, the one or more images of the tank from the inspection;

analyzing the one or more images of the tank to determine a liquid level for the tank, including a determination of a height of a liquid level within the tank relative to a top of the tank based on the one or more images of the tank;

calculating the amount of the liquid energy commodity in the tank based on the determined liquid level and the volume capacity information retrieved from the database; and

communicating information about the amount of the liquid energy commodity in the tank to a third-party market participant.

23. The method as recited in claim 12, in which the images include photographic images, infrared images, or both photographic images and infrared images.
