Your Pumper Calls in Sick Tomorrow. Do You Know What Happened on Your Wells Yesterday? There are over 770,000 stripper wells in the United States. Wells that SCADA forgot. Wells that "don't justify" a $30,000 install. Wells that still get monitored the same way they did twenty years ago: a truck, a clipboard, and a prayer. TinyPumper was built for the operators who run those wells. Know your tank levels without driving to the lease. Get an alert the hour production drops, not two weeks later when the revenue check is light. Find out your compressor went down at 2 AM while you're still drinking your morning coffee, not when your pumper rolls up 14 hours later. Be at your kid's baseball game. Glance at your phone. All wells running. Watch the game. That's what this does. Built in the oil patch. Proven across 22 states. 600+ production companies. 15 years. 220+ million barrels tracked. 100% continental US coverage, including leases with zero cell service. Installs in 10 minutes. No electrician. No trenching. No third parties. 60-day money-back guarantee. We pay return shipping. Every sensor ships with a lifetime replacement guarantee. No questions, no fine print, no expiration. TinyPumper is remote well monitoring for independents. For the operators who built their business with sweat, not stock options. For the wells that Wall Street doesn't talk about but America still runs on.
