Injection Wells in California

 Crucial Backbone of Oil Production

How it Works

Injection wells have been used for decades in California to assist in oil production – to increase oil recovery and safely dispose of water produced with oil and gas.

When oil is pumped from underground, it comes out co-mingled with water – called “produced water.” That water is either treated and used for enhanced oil recovery (EOR) or disposed of by injecting it back underground. A small portion is treated and provided for agricultural purposes, providing a critical source of irrigation water during the drought. This water must meet specific water quality standards and permit requirements dictated by local regulators.
