Plug in pump for inverted shroud assembly

A well fluid production assembly comprising:

• an upper production tubing string suspended in a cased well;
• a shroud connected to a lower end of the upper production tubing string;
• a motor assembly secured to and extending below the shroud and having a shaft end protruding into the shroud;
• a pump assembly lowered into the shroud, and stabbingly engaged to the shaft end of the motor assembly;
• an anti-rotation member in the shroud that is engaged by a pump in the pump assembly to prevent rotation of a housing of the pump, the pump having an intake in the shroud and a discharge on upper end;
• a lower production tubing string within the shroud and connected between the pump assembly and the upper production tubing sting;
• a hanger securing to the shroud and having an upper end connected to the upper production tubing string and a lower end connected to the lower tubing string;
• and
• an inlet in sidewall of the shroud at upper end for admission of well fluid to the pump assembly.

A method for producing well fluid from a well, comprising:

• a) securing a motor assembly to and below a lower end of a shroud such that a power shaft end protrudes into the shroud;
• b) making up a full length of the shroud and suspending in a cased well the shroud with the motor assembly attached thereto;
• c) securing a pump assembly to a lower end of a lower production tubing string and lowering the pump assembly on the lower production tubing string into the suspended shroud;
• d) stabbing a lower end of the pump assembly into the shaft end of the motor assembly;
• e) attaching an upper end of the lower production tubing string to an upper end of the shroud and to an upper production tubing string;
• f) lowering the shroud on the upper production tubing string to a desired depth in the well;
• g) operating the motor assembly to rotate the pump assembly, flowing well fluid through an inlet in the shroud to an intake of the pump assembly, and pumping well fluid through the lower and upper production tubing strings.
