Apparatus, systems, and methods for automated separation of sand from a wellbore slurry

1. A method for a sand separation system, the method comprising:

mounting two or more energy generators to a sand separator of a known type,

wherein the sand separator of the known type is adapted to separate sand from a wellbore slurry,

wherein the sand separator of the known type defines an internal region in which the separated sand is adapted to accumulate, and

wherein mounting the two or more energy generators to the sand separator of the known type comprises:

vertically spacing apart the two or more energy generators along a height of the sand separator of the known type, and

mounting the vertically-spaced-apart two or more energy generators to the sand separator of the known type outside of the internal region;

mounting two or more energy sensors to the sand separator of the known type,

wherein mounting the two or more energy sensors to the sand separator of the known type comprises:

vertically spacing apart the two or more energy sensors along the height of the sand separator of the known type, and

mounting the vertically-spaced-apart two or more energy sensors to the sand separator of the known type outside of the internal region;

imparting, using the two or more energy generators, energy to the sand separator of the known type,

wherein imparting the energy to the sand separator of the known type comprises administering one or more impacts against the sand separator of the known type using one or more strikers, each of the one or more strikers comprising a solenoid;

detecting, using the two or more energy sensors, a response to the energy imparted to the sand separator of the known type,

wherein the response detected by the two or more energy sensors comprises a vibrational response caused by the one or more impacts administered against the sand separator of the known type by the one or more strikers;

and

determining, using one or more computers, an unknown sand level of the separated sand accumulated in the internal region of the sand separator of the known type, the one or more computers being adapted to communicate with the two or more energy sensors and the two or more energy generators;

wherein the one or more computers, the two or more energy sensors, the two or more energy generators, or any combination thereof are pre-tuned based on:

known sand level(s) in:

the sand separator of the known type, and/or

another sand separator of the known type,

and

detected response(s) to energy imparted to:

the sand separator of the known type when the sand separator of the known type is filled with the known sand level(s), and/or

the another sand separator of the known type when the another sand separator of the known type is filled with the known sand level(s);

and

wherein the one or more computers determine the unknown sand level of the separated sand accumulated in the internal region of the sand separator of the known type based on:

the vibrational response detected by the two or more energy sensors and caused by the one or more impacts administered against the sand separator of the known type by the one or more strikers, and

the pre-tuning of the one or more computers, the two or more energy sensors, the two or more energy generators, or the any combination thereof.

2. The method of claim 1 ,

wherein mounting the two or more energy generators to the sand separator of the known type outside of the internal region comprises non-invasively mounting the two or more energy generators to the sand separator of the known type; and

wherein mounting the two or more energy sensors to the sand separator of the known type outside of the internal region comprises non-invasively mounting the two or more energy sensors to the sand separator of the known type.

3. The method of claim 1 , wherein the one or more computers, the two or more energy sensors, the two or more energy generators, or the any combination thereof are pre-tuned based on:

the known sand level(s) in the sand separator of the known type; and

the detected response(s) to the energy imparted to the sand separator of the known type when the sand separator of the known type is filled with the known sand level(s).

4. The method of claim 1 , wherein the one or more computers, the two or more energy sensors, the two or more energy generators, or the any combination thereof are pre-tuned based on:

the known sand level(s) in the another sand separator of the known type; and

the detected response(s) to the energy imparted to the another sand separator of the known type when the another sand separator of the known type is filled with the known sand level(s).

5. The method of claim 1 , wherein the sand separator of the known type is a vertical sand separator.

6. The method of claim 1 , wherein the sand separator of the known type is a spherical sand separator.

7. The method of claim 1 , wherein the sand separator of the known type is a cyclonic sand separator.
