Summary  
The documents detail personnel records and intelligence reports related to Winfield Clark Barnes, a U.S. national with ties to oil companies operating in Cuba during the 1960s. Barnes held positions as General Manager of Esso Standard Oil S.A. in Havana, Cuba, and later as Director of Esso Inter-America Inc. in Miami, Florida. His employment history includes roles at Humble Oil & Refining Company, Raco Standard Oil (Cuba Div), and International Petroleum Company, Ltd. The records include passport information, biographical data, and security clearances. Additional reports from the Central Intelligence Agency (CIA) discuss Cuba's oil industry challenges, including Soviet crude oil supply issues, refinery operations, lubricating oil shortages, and personnel movements within Cuban petroleum companies. These reports note technical difficulties with refining processes, concerns over technician departures affecting production, and internal discussions among employees regarding political ideologies and operational strategies.  

The document contains two separate intelligence reports from the Central Intelligence Agency (CIA) regarding Cuban activities and personnel in the oil industry during August 1960. The first report discusses an intervention by the Castro regime at a refinery in Cuba, involving former Cuban Navy Commander Oliveira Officer and Guardia Pino, described as an intelligent and hospitable individual with a beard. It notes tensions between Guardia and Pino regarding operational strategies and mentions Pino’s directive to Guards to remain in their posts and avoid public dissent. The second report focuses on Leoce de Paula Arinas, a Cuban national employed at the Eso Refinery, detailing his background as an engineer, his role in securing replacement parts for the refinery, and his family details. It also references challenges in employment opportunities in Latin America due to competition from other countries’ refining operations.
