Chemical Production

Technological inventions and discoveries, in the field of oil and gas were being led by Indiana Standard. They discovered PTA, a chemical for producing polyester fiber. This discovery spurted Amoco in acquiring Avisum Corporation and Pathogue-Plymouth which led to forming the Amoco Fabrics and Fibers.

In the 50’s and 60’s, Amoco expanded globally creating plants, oil wells in more than 30 countries in all the continents. It was on its way to becoming the leading oil companies in the world by acquiring Tenneco Oil company and Dome Petroleum company.

On August 11, 1998, Amoco announced it would merge with British Petroleum (BP) in the world's largest industrial merger. Originally, the plan was for all US BP service stations to be converted to Amoco while all overseas Amoco service stations were to be converted to BP. But by 2001 BP announced that all Amoco service stations would either be closed or renamed to BP service stations, including the remaining stations still bearing the "Standard" name. However, BP rebranded its gas as "Amoco Fuels", including "Amoco Ultimate". By 2008, the "Amoco Fuels" brand had been mostly discontinued in favor of "BP Gasoline with Invigorate", but the "Amoco Ultimate" name remains on the company's highest octane gasoline.

Few BP stations continue operation under the name Amoco, however, most were either converted to BP, some Amoco-style stations were demolished and replaced with BP-style stations, abandoned, or switched to competitor brands.
