Oil was discovered on company land in 1942 by the Humble Oil and Refining Company, today known as Exxon. Crude oil production commenced in 1943 and continues today. The Barron Collier Companies, together with Collier Enterprises, manages these substantial mineral holdings through Collier Resources Company (www.CollierResources.com).

Since 1990, Collier Resources has identified several potential new oil fields in Southwest Florida and is currently active in furthering exploration of the Colliers’ over 800,000 acres of mineral assets. The company also monitors oil production and development operations in three producing oil fields and the activities of oil operators in the region. In excess of 117 million barrels of oil have been extracted to date.
