Method and system for power generation

A method comprising:

• receiving, at an inlet of a flowline, a reservoir fluid from a well of a geological formation, wherein the flowline comprises a first flow path between the inlet and an outlet of the flowline and a second flow path between the inlet and the outlet, in parallel with the first flow path;
• regulating, via a choke valve disposed in the first flow path, a pressure differential of the reservoir fluid between the inlet and the outlet;
• and
• generating, via a turbine disposed in the second flow path, power, based on a flow of the reservoir fluid, induced by the pressure differential, through the turbine, wherein generating the power comprises generating, via a generator mechanically coupled to a rotor of the turbine, electrical power;
• adjusting, via a second choke valve disposed along the second flow path, a flow rate of the reservoir fluid through the turbine;
• and
• directing a second flow from a secondary flow line of the second flow path and prior to the second choke valve to the turbine, wherein the rotor of the turbine comprises a plurality of turbine blades, wherein each turbine blade of the plurality of turbine blades comprises one or more eyelets;
• excreting the second flow from the one or more eyelets of each blade of the plurality of turbine blades, thereby generating a boundary layer in front of each turbine blade, relative to the flow of the reservoir fluid through the turbine, wherein the boundary layer is configured to reduce a frequency, severity, or both of impacts of particulate matter in the reservoir fluid on the plurality of turbine blades.

A system comprising:

• a flowline comprising an inlet, an outlet, a first flow path between the inlet and the outlet, and a second flow path between the inlet and the outlet, in parallel with the first flow path, the flowline configured to receive, at the inlet, a hydrocarbon fluid at a first pressure from a well in a geological formation and output, at the outlet, the hydrocarbon fluid at a second pressure, wherein a difference between the first pressure and the second pressure comprises a pressure differential, and wherein the hydrocarbon fluid comprises particulate matter;
• a turbine comprising a rotor disposed in the second flow path, the rotor configured to rotate based on a flow of the hydrocarbon fluid through the second flow path, wherein the flow is induced by the pressure differential;
• a choke valve disposed on the first flow path and configured to regulate the pressure differential;
• and
• a nozzle valve disposed along the second flow path and configured to accelerate, via a nozzle within the nozzle valve, the flow and split the flow into a bypass flow and a turbine flow, wherein the turbine flow is output from the nozzle valve to the turbine after the nozzle and at an angle with respect to a direction of output of the nozzle, wherein the turbine flow comprises a lesser concentration of the particulate matter than the bypass flow.
