Distributed fluid injection system for wellbores

A resource exploration and recovery system comprising:

• a surface system including a fluid source;
• a subterranean system including a casing tubular extending into a wellbore of a formation, the wellbore including a vertical section and a horizontal section including a toe portion and a heel portion;
• and
• a fluid injection system extending into the second system from the first system, the fluid injection system comprising:
• a first fluid line including a first end, a second end, and an intermediate portion, the first end connected to the fluid source, the second end of the first fluid line including a first connector portion;
• an electric submersible pump (ESP) coupled to the first fluid line and arranged uphole of the first connector portion;
• and
• a second fluid line including a first end section, a second end section, and an intermediate section, the second fluid line extending along the horizontal portion and includes a plurality of fluidically connected fluid injectors arranged along the intermediate section, the first fluid line and the second fluid line being run into the wellbore with the ESP to perform wellbore operations, the first end section of the second fluid line including a second connector portion, the first connector portion of the first fluid line being selectively disconnectable from the second connector portion of the second fluid line allowing the first fluid line and the ESP to be withdrawn from the wellbore while the second fluid line and the plurality of fluidically connected fluid injectors remain downhole, the first connector portion being selectively reconnectable to the second connector portion of the second fluid line to continue wellbore operations after being withdrawn.

A method of injecting fluids into a horizontal section of a wellbore comprising:

• introducing a fluid injection system including an electric submersible pump (ESP) into a vertical section of the wellbore, the ESP being fluidically connected between a first fluid line and a second fluid line;
• guiding a portion of the second fluid line of the fluid injection system into the horizontal section of the wellbore;
• performing wellbore operations by injecting a fluid through the first fluid line, into the second fluid line and through a plurality of fluidically connected fluid injectors arranged along the portion of the fluid injection system;
• disconnecting a connector coupled between the ESP and the second fluid line of the fluid injection system in the horizontal section;
• withdrawing the first fluid line and the ESP from the wellbore;
• re-introducing the first fluid line and the ESP into the wellbore;
• and
• re-connecting the connector joining the ESP with the second fluid line to commence further wellbore operations.
