Abstract

Well completion design data for completing plural stages of a well completion operation is accessed. Predicted component life intervals for each of a plurality of components of a frac fleet are accessed. Remaining component life intervals for each of the plurality of components of the frac fleet are determined based on the predicted component life intervals. A continuous completion event for the well completion operation is set based on the remaining component life intervals for each of the plurality of components. The continuous completion event includes a continuous pumping block identifying one or more contiguous stages from among the plurality of stages during which the well completion operation is performed with the frac fleet, and a maintenance block identifying one or more of the plurality of frac pumps to be subject to predetermined maintenance operations upon completion of the one or more contiguous stages of the continuous pumping block.

First claim

What is claimed is:

1. A method comprising:
accessing well completion design data for completing a plurality of stages of a well completion operation, the well completion operation being performed with a frac fleet including a plurality of frac pump transports, each frac pump transport including a plurality of frac pumps, and each frac pump including a plurality of components;
accessing pump maintenance data associated with the plurality of components, the pump maintenance data including usage data of a plurality of historical well completion operations performed by the frac fleet;
analyzing the pump maintenance data to generate a maintenance prediction model, the maintenance prediction model being configured to output for each of the plurality of components, a predicted component life interval as a function of an operating condition of the well completion operation, and actual component life intervals and associated metrics of replaced components corresponding to the component, wherein the associated metrics include, for a given replaced component (i) a maintenance event metric indicating whether the given replaced component was replaced due to a preventative maintenance event or a failure maintenance event, and (ii) operating conditions during a life of the given replaced component, the operating conditions specifying frac job design metrics indicating pumping parameters associated with the given replaced component, wherein the predicted component life interval is measured in one of a number of pump strokes and a number of barrels pumped,
determining for each of the plurality of components of the frac fleet, a remaining component life interval based on the predicted component life interval and a tracked current component life; and
scheduling a continuous completion event for the well completion operation based on the remaining component life interval for each of the plurality of components, the continuous completion event including a continuous pumping block and a maintenance block, the continuous pumping block identifying one or more contiguous stages from among the plurality of stages during which the well completion operation is performed with the frac fleet, and the maintenance block identifying one or more of the plurality of frac pumps to be subject to predetermined maintenance operations upon completion of the one or more contiguous stages of the continuous pumping block.

2. The method of claim 1 , further comprising determining an estimated pump count value for completing each of the plurality of stages of the well completion operation based on the well completion design data.

3. The method of claim 2 , wherein the maintenance block identifies the one or more of the plurality of frac pumps in response to determining that the remaining component life interval of at least one of the plurality of components of each of the one or more of the plurality of frac pumps is within a predetermined threshold of estimated pump count values for completing the one or more contiguous stages of the continuous pumping block.

4. The method of claim 3 , wherein the predetermined maintenance operations include a maintenance event for the at least one of the plurality of components of each of the one or more of the plurality of frac pumps.

5. The method of claim 2 , wherein the remaining component life interval for each component and the estimated pump count value for each stage are measured as one of a number of pump strokes and a number of pumped barrels.

6. The method of claim 1 , wherein the plurality of components include, for each of the plurality of frac pumps of the frac fleet, a plurality of valves, a plurality of seats, a plurality of seals, a plurality of packings, a plurality of packing rings, a plurality of packing nuts, a plurality of plungers, and a fluid end assembly.

7. The method of claim 1 , wherein the well completion design data includes data for performing a hydraulic fracturing operation for each of a plurality of wells, and wherein each stage of the plurality of stages of the well completion design data performs the hydraulic fracturing operation for one of the plurality of wells.

8. The method of claim 1 , wherein the operating condition indicates a type of fluid pumped downhole during the well completion operation.

9. The method of claim 1 , wherein the tracked current component life is based on sensor output, and indicates a state of usage of the component across multiple well completion operations of the frac fleet.

10. A system for performing predictive block maintenance, the system comprising:
a frac fleet including a plurality of frac pump transports, each frac pump transport including a plurality of frac pumps, and each frac pump including a plurality of components;
memory; and
one or more processors operatively coupled to the memory, the memory comprising instructions that, when executed by the one or more processors, cause the one or more processors to:
access well completion design data for completing a plurality of stages of a well completion operation with the frac fleet;
access pump maintenance data associated with the plurality of components, the pump maintenance data including usage data of a plurality of historical well completion operations performed by the frac fleet;
analyze the pump maintenance data to generate a maintenance prediction model, the maintenance prediction model being configured to output for each of the plurality of components, a predicted component life interval as a function of an operating condition of the well completion operation, and actual component life intervals and associated metrics of replaced components corresponding to the component, wherein the associated metrics include, for a given replaced component (i) a maintenance event metric indicating whether the given replaced component was replaced due to a preventative maintenance event or a failure maintenance event, and (ii) operating conditions during a life of the given replaced component, the operating conditions specifying frac job design metrics indicating pumping parameters associated with the given replaced component, wherein the predicted component life interval is measured in one of a number of pump strokes and a number of barrels pumped,
determine for each of the plurality of components of the frac fleet, a remaining component life interval based on the predicted component life interval and a tracked current component life; and
schedule a continuous completion event for the well completion operation based on the remaining component life interval for each of the plurality of components, the continuous completion event including a continuous pumping block and a maintenance block, the continuous pumping block identifying one or more contiguous stages from among the plurality of stages during which the well completion operation is performed with the frac fleet, and the maintenance block identifying one or more of the plurality of frac pumps to be subject to predetermined maintenance operations upon completion of the one or more contiguous stages of the continuous pumping block.

11. The system of claim 10 , wherein the memory further comprises instructions that, when executed by the one or more processors, cause the one or more processors to determine an estimated pump count value for completing each of the plurality of stages of the well completion operation based on the well completion design data.
