CHEMICAL INJECTOR FOR PLUNGER LIFT
This patented system consists of a typical chemical pump, chemical chamber fitted atop a modified lubricator cap, all on the surface and a modified plunger available in any configuration currently on the market. The entire system has only 4 moving parts, not including the plunger. This system is capable of transporting liquid chemicals each plunger cycle. The entire system can be installed with common tools typically, during the shut-in segment of the well cycle. Field trials in two different wells in So. Louisiana over 168 days showed a reduction in metal loss (corrosion coupons before and during field trials) of 17% in one well and 3% in another well.The system incorporates non-metallic components to reduce metal loss caused by abrasion. The system can be set up to deploy multiple chemicals with a single system, i.e., corrosion inhibitors, foaming agents, oxygen scavengers, biocides, etc. The system is more efficient than capillary strings and much more economical to install and operate. It works in wells with packers in place and requires no service rig to install. There is no interruption in production during installation. The entire system, installed cost less than one application where chemical laden diesel is "bull headed" down the tubing, installation of a velocity string or batch treating down the "backside".
