Abstract
An injection method of use for treating a production fluid from a wellhead. An injection system comprising a chemical tanks, a skid assembly, a bacteria monitor, and a control panel. An actuated three-way valve selectively opens and closes to allow a portion of the production fluid into the bacteria monitor. The injection system adapted to selectively open the actuated three-way valve to receive a portion of the production fluid from the wellhead, receiving a portion of the production fluid from the wellhead, monitoring a chemical composition of the production fluid, selectively adding a mixture of chemicals from one or more chemical storage tanks into the production fluid, injecting the resulting mixture back into the wellhead, and monitoring the production fluid and modifying mixtures from the one or more chemical storage tanks and/or closing the actuated three-way valve according to a desired mixture.
