BJ Energy Solutions, LLC,...


1. A hydraulic fracturing unit assembly to pump fracturing fluid into a wellhead, the hydraulic fracturing unit assembly comprising:a chassis;
a gas turbine engine connected to the chassis, the gas turbine engine comprising:a compressor positioned to compress air;
a combustor section positioned to receive compressed air from the compressor and fuel, the combustor section positioned to combust at least a portion of the compressed air and fuel to provide heated combustion gas;
a compressor turbine shaft connected to the compressor such that the compressor turbine shaft rotates with the compressor;
a compressor turbine connected to the compressor turbine shaft such that the compressor turbine shaft and the compressor turbine rotate a first rotational speed;
a power turbine positioned downstream relative to the compressor turbine such that the heated combustion gas causes the power turbine to rotate at a second rotational speed; and
a power turbine output shaft connected to the power turbine such that the power turbine output shaft rotates with the power turbine at the second rotational speed, the compressor turbine shaft and the power turbine output shaft being rotatable at different rotational speeds;

a transmission comprising:a transmission input shaft connected to the power turbine output shaft such that the transmission input shaft rotates at the second rotational speed; and
a transmission output shaft positioned to be driven by the transmission input shaft at a third rotational speed;

a hydraulic fracturing pump positioned to pump fracturing fluid into the wellhead, the hydraulic fracturing pump comprising a pump drive shaft connected to the transmission output shaft such that the transmission output shaft drives the pump drive shaft at the third rotational speed;
one or more speed sensors associated with one or more of the compressor turbine shaft, the power turbine output shaft, or the pump drive shaft, the one or more speed sensors being configured to generate one or more rotational signals indicative of one or more of the first rotational speed, the second rotational speed, or the third rotational speed; and
a fracturing unit controller in communication with one or more of the gas turbine engine, the transmission, or the hydraulic fracturing pump, the fracturing unit controller being configured to:receive one or more target signals indicative of one or more of a target pressure associated with the fracturing fluid pumped into the wellhead or a target flow rate associated with the fracturing fluid pumped into the wellhead;
receive one or more fluid flow signals indicative of one or more of an actual pressure associated with the fracturing fluid pumped into the wellhead or an actual flow rate associated with the fracturing fluid pumped into the wellhead;
receive the one or more rotational signals;
control, based at least in part on one or more of the one or more target signals or the one or more fluid flow signals, one or more of the first rotational speed, the second rotational speed, or the third rotational speed; and
at least partially control, based at least in part on the one or more rotational signals, the third rotational speed of the pump drive shaft.
