Frac Pump Maintenance Scheduling for Continuous Pumping Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic fracturing operations face logistical challenges such as equipment downtime, environmental impact, and inefficiencies due to lack of predictive maintenance for frac pumps, leading to unscheduled maintenance and reduced operational efficiency.
Innovation Solution
A method and system for predictive block maintenance that uses a maintenance prediction model to determine component life intervals and set continuous completion events, allowing for scheduled maintenance and simultaneous maintenance of multiple components, thereby reducing downtime and increasing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maintenance scheduling is used for frac pumps, then equipment reliability is maintained through regular maintenance, but operational productivity decreases due to unscheduled downtime and non-productive time
Solution Approach 1:
The system performs preliminary maintenance actions by predicting component life intervals before actual failures occur. The maintenance prediction model analyzes component usage data and operational conditions to schedule maintenance during planned downtime between well completions, preventing unscheduled failures that would cause non-productive time and extend equipment downtime.
2Productivity
If predictive maintenance is implemented to reduce downtime, then productivity increases, but system complexity increases due to maintenance prediction models and data tracking requirements
Solution Approach 1:
The maintenance prediction model operates autonomously by automatically collecting component usage data from sensors and operational records, analyzing the data to predict remaining component life intervals, and generating maintenance schedules without requiring complex external intervention. The system serves itself by identifying when maintenance is needed based on actual component wear patterns rather than fixed schedules.
3Productivity
If continuous pumping blocks are extended to maximize operational efficiency, then productivity increases, but equipment reliability decreases due to prolonged operation without maintenance
Solution Approach 1:
The system dynamically adjusts maintenance scheduling parameters based on actual component usage data and operational conditions. Instead of fixed maintenance intervals, the maintenance prediction model calculates variable remaining component life intervals that reflect actual wear patterns, allowing continuous pumping blocks to be extended when components are operating within safe parameters while triggering maintenance when predicted intervals are approached.
4Loss of time
If maintenance is performed on multiple frac pumps simultaneously, then non-productive time is reduced through parallel maintenance operations, but coordination complexity increases
Solution Approach 1:
The system merges maintenance operations for multiple frac pumps by identifying components across different pumps that are due for maintenance within similar time windows. The maintenance prediction model generates coordinated schedules that allow maintenance crews to service multiple pumps simultaneously during the same maintenance window, consolidating what would otherwise be separate maintenance events into unified operations.

AI summary
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.
