Here’s an interesting aspect of the natural gas business you may not have heard about before (we hadn’t). As you may know, not all gas produced gets used immediately. Some gas gets stored, typically in underground caverns, and later extracted for use when needed. Buyers (like utility companies) contract with storage fields to park the gas they’ve purchased until they need it. What you may not know is that not 100% of the molecules that go in come back out again.
