Abstract
A method of lubricating a fluid production pump may include mixing a polarized lubricant with water to produce a diluted lubricant. The method may additionally include creating a flowpath within the fluid production pump. An initial volume of the diluted lubricant may be circulated within the flowpath to allow the diluted lubricant to react with components of the fluid production pump and form a protective barrier on the components of the fluid production pump. The method may further comprise repeatedly introducing a periodic volume of diluted lubricant into the fluid production pump according to a predefined lubrication schedule.
Claims7
A treatment regimen for an oil or gas producing well, the treatment regimen comprising the steps of:
- reconfiguring a pump of the well to a closed loop flow path from a normal flow path by utilizing a tube to connect an exit line of the pump to a feed line of the pump;
- introducing 100 ppm to 5000 ppm of a polarized lubricant based on a water cut of a production volume of the well per day into the pump wherein the polarized lubricant comprises a polar compound having a positive charge;
- recirculating the polarized lubricant in the pump in the closed loop flow path;
- mixing the polarized lubricant with a production fluid comprising oil and water during the recirculation step;
- returning the pump into the normal flow path from the closed loop flow path by removing the tube from the exit line of the pump to the feed line of the pump;
- and
- intermittently introducing the polarized lubricant into the pump.
