Artificial lift system and an associated method thereof

A method comprising:

• installing a reciprocating driver comprising a driver-shaft in a well bore;
• installing a reciprocating pump comprising a pump-shaft in the well bore;
• and
• applying a first force to the reciprocating pump, to detachably engage the pump-shaft to the driver-shaft.

A method comprising:

• powering a reciprocating driver disposed in a well bore, wherein the reciprocating driver comprises a driver-shaft;
• driving a reciprocating pump disposed in the well bore via the reciprocating driver, wherein the reciprocating pump comprises a pump-shaft detachably engaged to the driver-shaft;
• and
• pumping a production fluid from the well bore to a surface unit via a tubing, by driving the reciprocating pump.
