Abstract

A system and methodology facilitates the handling of oilfield material. The oilfield material is stored in at least one silo which enables use of gravity to feed the oilfield material to a blender or other suitable equipment. Each modular silo is transportable and may be engaged with a support structure via a pivot connection. Once engaged, the silo is pivoted to a raised, upright position on the support structure. The oilfield material is then moved to an interior of the silo, and gravity may be used to feed the oilfield material to a blender or other equipment in a controlled manner.

First claim

What is claimed is:

1. A method, comprising:
providing a silo with an enclosed interior for holding an oilfield material;
positioning the silo in a lateral position on a trailer;
backing the trailer toward a support structure to engage a portion of the support structure with a portion of the silo,
connecting the silo and the support structure together via a first connection while the silo is in the lateral position;
erecting the silo from the lateral position to an upright position on the support structure while the silo and the support structure are connected, the silo, in the upright position and the support structure defining a passage thereunder;
at least partially filling the silo with the oilfield material; and
moving a portable blending system into the passage defined by the silo and the support structure, wherein the support structure defines the height of the passageway prior to connecting the silo.

2. The method as recited in claim 1 , wherein the support structure defines a plurality of silo receiving areas designed to support at least two silos in an upright position; and further comprising repeating providing, positioning, backing, connecting, erecting, and at least partially filling for each of the at least two silos.

3. The method as recited in claim 1 , further comprising locating load cells on the support structure to measure the amount of oilfield material in the silo.

4. The method as recited in claim 1 , wherein the first connection comprises a pivot connection formed with a plurality of pins received in a plurality of pin receivers.

5. The method as recited in claim 1 , further comprising using expandable bases on the support structure to stabilize the silo.

6. The method as recited in claim 1 , wherein providing comprises enclosing a vertical conveyor in the enclosed interior to lift proppant related material from a lower end of the silo to an upper discharge end of the silo.

7. The method as recited in claim 1 , wherein erecting comprises pivoting the silo from the trailer into a desired configuration on the support structure.

8. The method as recited in claim 1 further comprising providing alignment guides on the support structure for aligning the trailer while backing the trailer toward the support structure.

9. The method as recited in claim 1 , wherein providing comprises providing the silo with a supporting silo frame.

10. The method as recited in claim 9 , wherein the silo frame supports an outer housing of the silo.

11. The method as recited in claim 1 , wherein the first connection comprises pivot connectors positioned to allow engagement and connection of the silo with the support structure while the silo is in the lateral position.

12. The method as recited in claim 1 , further comprising performing a fracturing operation and utilizing the silo and the portable blending system to provide oilfield material for the fracturing operation.

13. The method as recited in claim 1 , wherein the support structure comprises a support frame integrated into a trailer chassis.

14. The method as recited in claim 13 , wherein the support structure comprises a support base underneath the support frame, the support base having a first side and a second side, and wherein the support structure further comprises a first expandable base on the first side of the support base, and a second expandable base on the second side of the support base.

15. The method as recited in claim 1 , wherein the support structure comprises a base, and wherein the first connection comprises a plurality of first pivot members mounted on the base.

16. The method as recited in claim 15 , wherein the first connection comprises a plurality of second pivot members positioned at a rear of a trailer for transporting the silo, and wherein the plurality of first pivot members of the first connection are mounted on the support structure at a height which enables engagement with the plurality of second pivot members of the first connection when the silo is in the lateral position on the trailer.

17. The method as recited in claim 1 , wherein the support structure holds the silo above the blending system such that the silo overlaps at least a portion of the blending system.

18. The method as recited in claim 17 , wherein the support structure holds the silo at a sufficient height in the upright orientation to enable the portable blending system to be positioned in the passage during unloading of the oilfield material from the silo.

19. The method as recited in claim 17 , wherein the support structure includes a support base, and wherein the blending system is integrated into and supported by the support base.

20. The method as recited in claim 1 , wherein the support structure has a second connection spaced a distance from the first connection, and wherein the silo has a silo connection configured to connect with a support connection when the silo is in the upright orientation.

21. The method as recited in claim 20 , wherein the support structure has a base, and wherein the first and second connections are connected to the base, and wherein the silo and the support connections have different elevations relative to the base.
