The Unión Cuba Petróleo (Cupet) and the Chinese company Gran Muralla executed, in 546 days, the Varadero 1012 well, among the horizontal ones, the longest now, with 8 047 meters in length. The project was designed by Cuban engineers and specialists, as a contribution to the strategic objective of the country’s energy self-sufficiency.
The work is also located in the area of greatest prospects in the Varadero Oeste field, between the two most productive wells in the North Heavy Crude Strip, separated by approximately one kilometer, the head of drilling operations, Juan Carlos de la Concepción Fariñas, told Cuban TV.
Adrián Bacallao Ramírez, a specialist in the design of oil wells, highlighted the infrequency of drilling operations of such magnitude in the world, and even less in this geographic area. The construction reaches more than 7,000 meters of displacement in the seabed, where its reserves are located.
Previously, the longest well was Varadero 1011, completed in 2021, with a distance of 7,710 meters, the report detailed.
In spite of the obstacles and limitations linked to the blockade, it adds, the oil industry is turning technological innovation and science into priority strategies to continue its development and advance towards the energy sovereignty of the largest of the Antilles.
