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.
Claims8
A diluted lubricant for a fluid production pump, the diluted lubricant comprising:
- a polarized lubricant formed from a plant based fluid and including an emulsifier;
- and
- water;
- a ratio of water to polarized lubricant being in the range of 1:1-13:1.
An artificial lift system for pumping a liquid out of a ground comprising:
- a pump;
- a lubricant reservoir of diluted polarized lubricant.
A treatment regimen for a 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;
- introducing 100 ppm to 5000 ppm of a lubricant based on a production of the well per day into the pump;
- recirculating the lubricant in the pump in the closed loop flow path;
- mixing the lubricant with the production fluid during the recirculation step;
- returning the pump into the normal flow path from the closed loop flow path;
- and
- intermittently the lubricant into the pump.
