CaribX is a UK head quartered private oil and gas exploration company formed in 2009 to study and develop the hydrocarbon potential of the Caribbean and Central America, and to screen and mature exploration opportunities. 

CaribX's objective is to build and develop a large exploration portfolio in this under-explored area and to:

  1. Build on its unique understanding of the hydrocarbon potential of the Caribbean and Central American through detailed petroleum geological studies, original thinking and interpretation; 

  2. Select the most prospective areas and attract financial and industry partners; 

  3. Safely and responsibly develop this potential in partnership with countries, investors and operating partners.

CaribX is now recognised as the leading expert on the exploration potential of the region. The company has partnered with major international oil companies and holds a non-operated interest in the Main Cape project, offshore Honduras.
