Abstract:
1. A method of pumping a fluid into a string of tubing suspended from a wellhead within casing in a well, wherein the well contains a pump located at a lower end of the string of tubing that is rotated by a string of rods extending through the tubing to a motor assembly mounted to the wellhead, comprising: (a) closing a lower end of an elastomeric hose and pumping a fluid into the hose while the lower end of the hose is closed to create internal pressure in the hose to increase rigidity of the hose; (b) inserting the hose through a port in a sidewall of the wellhead and causing the hose to deflect and move downward from the port into the tubing alongside the string of rods; and (c) increasing the internal pressure in the hose to a level sufficient to cause the lower end of the hose to open, and discharging the fluid into the tubing.
