Abstract

According to one aspect, data identifying a component is received, wherein the component is part of a system associated with a wellhead. A location at which the component is positioned relative to one or more other components is identified. The useful remaining operational life of the component is predicted based on at least an operational parameter specific to the location, and the operational history of the component or one or more components equivalent thereto. According to another aspect, a model representing at least a portion of a proposed system associated with a wellhead is generated, the model comprising a plurality of objects, each of which has a proposed location and represents an existing component. The useful remaining operational life for each object is predicted based on an operational parameter at the corresponding proposed location, and data associated with the respective operational history of the existing component.

First claim

What is claimed is:

1. A method, comprising:
receiving, using a computer, data identifying a first component in a first plurality of components,
wherein the first plurality of components is part of a system associated with a wellhead,
wherein the first component has a useful remaining operational life,
wherein receiving the data identifying the first component comprises receiving data associated with a first reading of a first identifier that is coupled to the first component, and
wherein the first reading is part of a first plurality of readings to be taken in a first predetermined order, each place in the first predetermined order corresponding to a respective location of one component in the first plurality of components;

identifying, using the computer, a first location at which the first component is positioned relative to one or more other components in the first plurality of components,
wherein identifying the first location at which the first component is positioned comprises determining the place in the first predetermined order at which the first reading was made;

receiving, using the computer, data associated with a first operational parameter specific to the first location;
receiving, using the computer, data associated with an operational history of the first component or one or more components equivalent thereto; and
predicting, using the computer, the useful remaining operational life of the first component based on at least:
the first operational parameter, and
the operational history of the first component or one or more components equivalent thereto.

2. The method of claim 1 , wherein the system associated with the wellhead is a system for pumping fluid to the wellhead.

3. The method of claim 1 , wherein receiving data associated with the first reading of the first identifier further comprises:
positioning at least one reader in the vicinity of the first component;
reading the first identifier using the at least one reader to thereby obtain the first reading; and
transmitting the data associated with the first reading to the computer.

4. The method of claim 3 , wherein the first identifier comprises an RFID tag; and
wherein the at least one reader is an RFID reader.

5. The method of claim 1 , wherein the first operational parameter is selected from the group consisting of a fluid flow rate through the first component, a fluid pressure within the first component, a volume of media within the first component, a volume of proppant within the first component, a volume of sand within the first component, and a time period during which fluid is to be pumped through the first component.

6. The method of claim 1 , wherein the first operational parameter specifies a value or range of values; and
wherein receiving data associated with the operational history comprises:
receiving data associated with measurements of one or more wear life attributes of the first component or one or more components equivalent thereto taken against time and under one or more operational parameters, the one or more operational parameters having the same, or different, values or ranges of values than that specified by the first operational parameter; and
storing the data associated with the wear life attribute measurements and the one or more operational parameters made thereunder; and
querying the stored data.

7. The method of claim 1 , wherein predicting the useful remaining operational life of the first component comprises:
determining a wear trend for the first component based on at least the first operational parameter and the data associated with the operational history of the first component or one or more components equivalent thereto; and
predicting the useful remaining operational life of the first component using the wear trend.

8. The method of claim 1 , further comprising:
(a) receiving, using the computer, data identifying another component in the first plurality of components, wherein the another component has a useful remaining operational life;
(b) identifying, using the computer, another location at which the another component is positioned relative to one or more other components in the first plurality of components;
(c) receiving, using the computer, data associated with another operational parameter specific to the another location;
(d) receiving, using the computer, data associated with an operational history of the another component or one or more components equivalent thereto;
(e) predicting, using the computer, the useful remaining operational life of the another component based on at least:
the another operational parameter, and
the operational history of the another component or one or more components equivalent thereto; and

(f) repeating (a)-(e) until the respective useful remaining operational lives of all the components in the first plurality of components have been predicted.

9. The method of claim 1 , further comprising:
receiving, using the computer, data identifying a second component in a second plurality of components,
wherein the second plurality of components is part of the system associated with the wellhead, and
wherein the second component has a useful remaining operational life;

identifying, using the computer, a second location at which the second component is positioned relative to one or more other components in the second plurality of components;
receiving, using the computer, data associated with a second operational parameter specific to the second location;
receiving, using the computer, data associated with an operational history of the second component or one or more components equivalent thereto; and
predicting, using the computer, the useful remaining operational life of the second component based on at least:
the second operational parameter, and
the operational history of the second component or one or more components equivalent thereto.

10. An apparatus, comprising:
a non-transitory computer readable medium; and
a plurality of instructions stored on the non-transitory computer readable medium and executable by a processor, the plurality of instructions comprising:
instructions that cause the processor to receive data identifying a first component in a first plurality of components,
wherein the instructions that cause the processor to receive the data identifying the first component comprise instructions that cause the processor to receive data associated with a first reading of a first identifier that is coupled to the first component,
wherein the first reading is part of a first plurality of readings to be taken in a first predetermined order, each place in the first predetermined order corresponding to a respective location of one component in the first plurality of components,
wherein the first plurality of components is part of a system associated with a wellhead, and
wherein the first component has a useful remaining operational life;

instructions that cause the processor to identify a first location at which the first component is positioned relative to one or more other components in the first plurality of components,
wherein the instructions that cause the processor to identify the first location at which the first component is positioned comprises instructions that cause the processor to determine the place in the first predetermined order at which the first reading was made;

instructions that cause the processor to receive data associated with a first operational parameter specific to the first location;
instructions that cause the processor to receive data associated with an operational history of the first component or one or more components equivalent thereto; and
instructions that c
