Located in the Gorgoglione concession, in the upper Sauro valley, at the heart of the Basilicata region in southern Italy, the Tempa Rossa oil and gas field was first discovered in 1989 by the PetroFina teams. Many geotechnical, industrial, administrative, societal and environmental issues were faced. Following these challenges, the first drops of oil were extracted from the site in September 2018.
A Significant Production of Oil, Gas and LPG
The Tempa Rossa production site covers an area of 27 hectares at an altitude of 1,050 meters. It includes 6 wells – drilled up to a depth of 7,148 meters – is equipped with dual electric pump systems and is tied back to the Oil Processing Center by an underground gathering system. The two remaining wells will be drilled in the coming years. Each well is designed to produce between 8,000 and 15,000 barrels of oil per day. Construction works included the excavation of 2.5 million cubic meters of earth and land draining and stabilization in an area prone to earthquakes. A total of 5,000 piles were sunk into the ground to build the 50,000-b/d Oil Processing Center.
Technical and Environmental Expertise Adapted to Tempa Rossa
The Tempa Rossa crude oil, which has a gravity of between 10° and 22° API, is heavy, viscous and contains sulfur. The Oil Processing Center therefore features steam generators to heat the oil, gas and steam turbines to generate electricity, as well as a complex gas processing line to extract the sulfur, an LPG separation unit and an innovative water treatment center. All Tempa Rossa site facilities were designed and delivered according to the best environmental practices, with real-time monitoring of environmental parameters.
From the Oil Center, the methane gas is fed through a buried pipeline into the local Snam distribution network, while the LPG is also channeled via a buried pipeline to the LPG storage center in the valley and then trucked away. The liquid sulfur is shipped directly from the Oil Center by trucks. Finally, the oil is sent by pipeline from the Oil Center to the Val d'Agri-Taranto pipeline, which has a 20" diameter and runs a distance of 136 kilometers, linking the neighboring Val d'Agri installations to the Taranto refinery and its export terminal. In Taranto, until the definitive export facilities under construction become operational at the end of 2021 and allow for the full export of the crude production, approximately one-third of the output will be refined, while the remaining two-thirds will be exported through the existing facilities.
