Petrotrin, also known as the Petroleum Company of Trinidad and Tobago Limited, was a state-owned oil company based in Trinidad and Tobago. Its origins can be traced back to 1911 when the Trinidad Government Oilfields (TGO) was established. In 1993, TGO merged with Trintoc, the Trinidad and Tobago Oil Company, to form Petrotrin.

The company's headquarters was located in Pointe-à-Pierre, Trinidad. This sprawling complex housed various administrative offices, refining facilities, and storage tanks. It also featured a laboratory for quality testing and research.

Petrotrin primarily engaged in the exploration, production, refining, and marketing of crude oil, natural gas, and petroleum products. The company operated both onshore and offshore oil fields in Trinidad and Tobago. It had an extensive network of pipelines and storage facilities to transport and store the oil and gas produced.

In terms of global operations, Petrotrin had numerous subsidiaries and joint ventures. Some notable subsidiaries included Trinmar Limited, Petrotrin Marine, and Petrotrin Deed Restricted. The company also partnered with international energy giants such as Chevron and Shell to explore and develop hydrocarbon reserves in Trinidad and Tobago.

Petrotrin held a significant market position in the oil and gas industry, both domestically and internationally. It was one of the largest oil companies in the Caribbean region and was a major contributor to Trinidad and Tobago's economy. The company's products were exported to various countries around the world, further strengthening its global presence.

Over the years, Petrotrin underwent several significant changes and achievements. In 2018, the company faced financial difficulties and was ultimately shut down. The government formed a new state-owned entity, The Trinidad and Tobago Petroleum Company (TTPEL), to handle Petrotrin's assets.

This decision marked a significant turning point in the company's history. As of the latest information available, Petrotrin has ceased operations, and TTPEL currently manages its assets. The closure of Petrotrin had a profound impact on the energy sector and the economy of Trinidad and Tobago.

The country continues to rely on its petroleum resources, and the future of the industry remains a critical aspect of its development plans
