Abstract
Methods and systems pertaining to generating a startup or other operating order of pumps of a pumping system for performing a subterranean formation fracturing operation, and/or another pumping operation, and for coordinating distribution of flow rates to the pumps for performing the pumping operation.
Claims18
A method (500) comprising:
- generating (502) a startup order of pumps (150) of a pumping system (135) for performing a subterranean formation (106) fracturing operation;
- determining (528) that a pump order list does not include enough pumps for pumping fracturing fluid for the fracturing operation;
- and then
- iteratively, until the pump order list includes enough pumps for pumping fracturing fluid for the fracturing operation:
- identifying (530) a next one of the pumps that is not on the pump order list and that is available for pumping fracturing fluid for the fracturing operation;
- and
- adding (532) the identified next available fracturing fluid pump to the end of the then-current pump order list;
- and
- coordinating (504) distribution of flow rates to the pumps.
