Abstract
A method of controlling a pumping sequence of a fracturing fleet at a wellsite. A managing application executing on a computer in the control van can retrieve the pumping sequence from a local or remote storage computer. The managing application can establish an electronic communication link to receive sensor data from a plurality of fracturing units. The managing application can control the plurality of fracturing units with a stage script with multiple sequential instructions for a pumping stage of a pumping sequence while receiving one or more periodic data sets from the plurality of fracturing units wherein the data sets are indicative of the current state of the pumping stage of the pumping sequence.
Claims20
A method of controlling a pumping sequence of a fracturing fleet at a wellsite, comprising:
- loading, by a managing application executing on a computer at the wellsite, a pumping sequence;
- establishing electronic communication between the managing application and a plurality of fracturing units located at the wellsite;
- retrieving, by the managing application, one or more periodic datasets from at least one sensor associated with each of the plurality of fracturing units, and wherein the one or more periodic datasets are indicative of a current operation of each of the plurality of fracturing units;
- starting a stage script, by the managing application, with multiple sequential instructions for a pumping stage of a pumping sequence;
- controlling, by the managing application, the plurality of fracturing units in accordance with the stage script;
- receiving, by the managing application, at least one operational exception from one or more of the plurality of fracturing units;
- and
- in response to receiving the operational exception, isolating, by the managing application, one or more fracturing units by an instrumented package via an automated exception sub-script.
A method of controlling a pumping sequence of a fracturing fleet at a wellsite, comprising:
- loading, by a managing application executing on a computer at the wellsite, a pumping sequence;
- establishing electronic communication between the managing application and a plurality of fracturing units located at the wellsite;
- retrieving, by the managing application, one or more periodic datasets from at least one sensor associated with each of the plurality of fracturing units, and wherein the one or more periodic datasets are indicative of a current operation of each of the plurality of fracturing units;
- starting a stage script, by the managing application, with multiple sequential instructions for a pumping stage of a pumping sequence;
- controlling, by the managing application, the plurality of fracturing units in accordance with the stage script;
- receiving, by the managing application, at least one operational exception from a fracturing pump;
- and
- in response to receiving the operational exception, isolating, by the managing application, the fracturing pump by i) reducing a pumping load to zero and ii) closing an isolation valve on an instrumented package via an automated exception sub-script.
A method of controlling a pumping sequence of a fracturing fleet at a wellsite, comprising:
- loading, by a managing application executing on a computer at the wellsite, a pumping sequence;
- establishing electronic communication between the managing application and a plurality of fracturing units located at the wellsite;
- retrieving, by the managing application, one or more periodic datasets from at least one wellbore sensor or wellhead sensor, and wherein the one or more periodic datasets are indicative of a wellbore environment;
- starting a stage script, by the managing application, with multiple sequential instructions for a pumping stage of a pumping sequence;
- controlling, by the managing application, the plurality of fracturing units in accordance with the stage script;
- receiving, by the managing application, at least one operational exception from a fracturing unit, a wellbore sensor, or a wellhead sensor;
- and
- in response to receiving the operational exception, starting, by the managing application, a second set of fracturing units by i) beginning a pumping load from zero and ii) opening an isolation valve on an instrumented package via an automated exception sub-script.
