By Amanda Leon, founder of OilMoney.io. Houston-raised, came up in the Houston marketing team of Vallourec, and has run Unrth, a brand and growth studio for oil and gas and industrial companies, since 2017, with her boots on client locations in Midland and Odessa. Last reviewed November 5, 2026.
We read every notice in the Texas Workforce Commission's WARN list from January 2020 through late October 2026, 2,278 unique filings, and picked out the oil and gas employers one by one. That left 161 notices covering 24,138 workers. 103 of those notices and 15,735 of those workers came in 2020 alone. The most recent oil and gas notice on the list is Baker Hughes in Houston, filed July 1, 2026, for 174 workers. Every filing is listed below by year.
What a WARN Notice Is
The federal Worker Adjustment and Retraining Notification Act generally requires larger employers to give 60 days' notice before a plant closing or mass layoff. The U.S. Department of Labor explains the rules, and in Texas the notices go to the Texas Workforce Commission, which publishes them by year. A notice is the employer's own filing, so it tells you the employer, the site, the county, the number of workers, and the dates. It doesn't tell you why.
How We Read It
We downloaded the state's seven yearly files on November 2, 2026, and removed exact duplicate rows, which left 2,278 notices.
We read the employer names one by one and kept those clearly in oil and gas: operators, service companies, offshore drillers, tubular and equipment makers, frac sand, oilfield logistics, midstream, and construction at oil and gas sites.
Worker counts are as filed. One layoff can produce several notices, one per site, and a company can file an update. The Zachry count at Sabine Pass, for example, was filed in June 2024 as 4,072 and followed by a 33-worker update.
Limits: smaller companies usually aren't covered, so many oilfield layoffs never show up here. A name that doesn't say what the company does may have been missed, and we left out refineries, chemical plants, and power companies. A notice shows what was planned, and the final number can differ.
What the Numbers Show
2026: 1 notices, 174 workers.
2025: 14 notices, 1,151 workers.
2024: 15 notices, 5,442 workers.
2023: 14 notices, 362 workers.
2022: 2 notices, 168 workers.
2021: 12 notices, 1,106 workers.
2020: 103 notices, 15,735 workers.
April 2020 alone produced 58 oil and gas notices. Many of those came from field towns such as Odessa, Midland, Pleasanton, Kermit, and Monahans, along with Houston. The biggest filings since 2024 look different. Set aside construction jobs on the Gulf Coast, and the largest are Chevron and Hess in Houston (575), Marathon Oil in Houston (500), ExxonMobil in Irving (376), Chevron in Midland (200), Baker Hughes in Houston (174), and Encino in Houston (121). Over the full period, service companies account for the most workers (11,647), followed by construction at oil and gas sites (4,635) and operators (4,177).
The largest filers across the whole period:
Halliburton: 5,672 workers.
Zachry (Sabine Pass): 4,105 workers.
ExxonMobil / XTO: 1,298 workers.
NexTier: 1,081 workers.
Hydraulic fracturing facility (name not given): 780 workers.
Chevron: 775 workers.
Basic Energy Services: 710 workers.
ProPetro: 655 workers.
What It Means for a Rep
Growing up in Houston, everyone around you is in oil and gas. It's baked into the culture, into the blood of the people. My dad has been in and out of the trucking industry. So this list reads personal to me. These are people you've been selling to.
Your contact may be on the move. When a customer files, the engineer who liked you may land somewhere else. Stay in touch with people, not just accounts. People remember who checked on them.
Check the budget before you call. A notice from a customer is a reason to ask what changed before you pitch. For the wider picture, read what to do when oil drops and your pipeline dries up.
Watch for ownership changes. If a filing follows a sale, start with what happens to a house account when an operator gets bought.
Don't wait until your own name is on one. Selling oilfield services through a downturn covers what holds up when the entertainment budget goes.
By county: Midland, Ector, and Harris.
