Automated multi-silo aggregate management
Methods of managing aggregate inventory. The methods include utilizing a dynamic protocol for an oilfield operation with aggregate from chambers of a multi-silo system wherein each chamber accommodates a single aggregate type throughout operations. However, the chambers also have a dynamic classification as either active, idle or reserved depending on the stage of operations. Once more, even though each silo may accommodate multiple chambers, unique techniques may be utilized to obtain real-time inventory information for each chamber via weight measurement of entire silos.
1. A method of managing aggregate at an oilfield with a mobile multi-silo system, each silo of the mobile multi-silo system having multiple chambers therein, the method comprising:
establishing a dynamic protocol for an operation at the oilfield utilizing at least one aggregate;
assigning each chamber a static designation for accommodating a given aggregate type throughout the operation at the outset of the operation;
discharging at least one aggregate from at least one of the chambers to a mixer disposed below each of the chambers of the mobile multi-silo system;
running the operation at the oilfield with at least one aggregate from the mobile multi-silo system filled according to the static designation and the dynamic protocol;
determining an amount of aggregate in each chamber based on weight information determined by a weight determining mechanism while running the operation;
classifying each chamber with a dynamic classification based at least in part on the determined amount of aggregate in each chamber, the classification dependent upon the dynamic protocol while running the operation; and
refilling a chamber in accordance with the dynamic protocol in light of the dynamic classification to enable running of the operation substantially continuously.
2. The method of claim 1 wherein classifying comprises classifying each chamber as one of idle and available for loading, idle and available for filling, active and loading, active and unloading and reserved to prohibit loading and unloading.
3. The method of claim 2 wherein classifying a chamber as reserved comprises:
confirming that the chamber is available for activating at a later point in time; and
confirming that another chamber of the same designated aggregate type is both available for activating at a present time and unavailable for activating at the later point in time.
4. The method of claim 1 wherein the assigning of the static designation to each chamber comprises operator manual entry thereof at an interface screen of a unit with a processor having the dynamic protocol stored thereon.
5. The method of claim 1 wherein the assigning of the static designation to each chamber comprises operator selection of a file at an interface screen of a unit with a processor having the dynamic protocol and the file stored thereon.
6. The method of claim 1 wherein the assigning of the static designations comprises assigning multiple chambers of the mobile multi-silo system the same aggregate type.
7. The method of claim 1 further comprising:
filling each chamber with an aggregate type; and
storing information regarding each filled chamber and aggregate type at a processor for the running of the operation.
8. The method of claim 7 wherein classifying a single chamber of a silo as active prohibits classification of any other chamber of the silo as active.
9. The method of claim 1 wherein the running of the operation at the oilfield comprises:
mixing the at least one aggregate in the mixer to form a slurry for the operation; and
performing a stimulation application in a well at the oilfield with the slurry.
10. The method of claim 9 wherein the at least one aggregate is proppant and the stimulation application includes fracturing downhole in the well.
11. A method of managing aggregate at an oilfield with a multi-silo system, each silo of the multi-silo system having multiple chambers therein, the method comprising:
establishing a dynamic protocol for an operation at the oilfield utilizing at least one aggregate;
assigning each chamber a static designation for accommodating a given aggregate type throughout the operation at the outset of the operation;
determining an amount of aggregate in each chamber based on weight information determined by a weight determining mechanism while running the operation;
classifying each chamber with a dynamic classification based at least in part on the determined amount of aggregate in each chamber, the classification dependent upon the dynamic protocol while running the operation; and
running the operation at the oilfield with at least one aggregate from the multi-silo system according to the dynamic protocol, the static designation, and the dynamic classification.
12. The method of claim 11 wherein classifying comprises classifying each chamber as one of idle and available for loading, idle and available for filling, active and loading, active and unloading and reserved to prohibit loading and unloading.
13. The method of claim 12 wherein classifying a chamber as reserved comprises:
confirming that the chamber is available for activating at a later point in time; and
confirming that another chamber of the same designated aggregate type is both available for activating at a present time and unavailable for activating at the later point in time.
14. The method of claim 11 wherein the assigning of the static designation to each chamber comprises operator manual entry thereof at an interface screen of a unit with a processor having the dynamic protocol stored thereon.
15. The method of claim 11 wherein the assigning of the static designation to each chamber comprises operator selection of a file at an interface screen of a unit with a processor having the dynamic protocol and the file stored thereon.
16. The method of claim 11 wherein the assigning of the static designations comprises assigning multiple chambers of the multi-silo system the same aggregate type.
17. The method of claim 11 further comprising:
filling each chamber with an aggregate type; and
storing information regarding each filled chamber and aggregate type at a processor for the running of the operation.
18. The method of claim 17 wherein classifying a single chamber of a silo as active prohibits classification of any other chamber of the silo as active.
19. The method of claim 11 wherein the running of the operation at the oilfield comprises:
mixing the at least one aggregate in the mixer to form a slurry for the operation; and
performing a stimulation application in a well at the oilfield with the slurry.
20. The method of claim 19 wherein the at least one aggregate is proppant and the stimulation application includes fracturing downhole in the well.
