Our first well · Schnitzer #2 · Alfalfa County, Oklahoma

The life of one orphaned well, from 1982 to its plug in 2025.

It produced gas for three decades, passed through six operators and was left leaking on the state’s orphan list. We found it in 2025, measured it, took it on and plugged it. This is its record, from the state filings and our own field file.

Three decades of dry gas from the Oswego, then nothing.

The well was drilled in October 1982 by an independent operator from Midland, Texas, and first gas went to sales on 3 November that year. It was perforated in the Oswego formation at 5,492 to 5,540 feet in the Anadarko Basin and never produced oil. Over its life it made about 160 million cubic feet of gas, and no production was reported after December 2013.

First gas was in November 1982, and the well was plugged in September 2025.

How a producing well becomes the state’s problem.

Each sale moved the eventual plugging bill to a new owner. Two operators took the well on after the gas had stopped, and the last of them, formed in 2018, no longer exists. By 2022 the well was on Oklahoma’s orphan list, leaking from a pinhole in the wellhead adaptor.

About 52 litres of methane a minute, measured as found.

We found the leak in May 2025, on a survey made with the landowner’s permission. Our engineering manager, a Professional Engineer, then led four sets of high-flow measurements between May and August 2025, with every valve left closed, and the readings averaged about 52 litres per minute.

Plugged on 4 September 2025, and verified independently.

We took on the well as its operator of record, which made us responsible for plugging it. ORR Energy Services, a Tulsa plug-and-abandon crew, ran the rig and cement, and we restored the site afterwards. TAQ Energy verified the work independently.

What the plug stopped
27 million L

of gas a year, which is what a leak of about 52 litres a minute adds up to for every year it stays open.
