Abstract
A method of fracturing may comprise: varying a plurality of operational parameters of wellbore servicing equipment; observing a response of the wellbore servicing equipment; generating a model of the wellbore servicing equipment based on the response; and changing at least one of the plurality of operational parameters based at least in part on the model.
Claims18
A method of fracturing comprising:
- pumping a wellbore treatment fluid into a subterranean formation using wellbore servicing equipment comprising a plurality of pumps;
- varying a plurality of operational parameters of the wellbore servicing equipment;
- observing a response of the wellbore servicing equipment;
- generating a model of the plurality of pumps based on the response;
- changing a horsepower output of two or more of the plurality of pumps based at least in part on the model to form an updated plurality of operational parameters such that a rate of wellbore treatment does not change more than about 10%;
- pumping the wellbore treatment fluid into the subterranean formation using the wellbore servicing equipment wherein the wellbore servicing equipment is operated at the updated plurality of operational parameters;
- and
- updating the updated plurality of operational parameters of the wellbore servicing equipment based at least in part on the model, such that the plurality of pumps are operated such that mechanical vibrations are avoided wherein the model is utilized to predict oscillation frequencies in manifold and discharge lines and the operational parameter of the wellbore servicing equipment is changed to reduce the oscillation frequencies in manifold and discharge lines.
