Hasdrubal oil and gas field is located 100km offshore Tunisia in the Gulf of Gabes. It lies in the 1,584km² Amilcar exploration permit at a water depth of 62m. The field came on-stream in March 2009. African Development Bank Group provided a loan of US$150m for development of the field. Hasdrubal was discovered by Elf (Sofratep) in 1975 but was declared non-commercial.
BG drilled three appraisal wells, which confirmed the commerciality of the field. The first well, Hasdrubal-2, was drilled in 1994. In June 1997 a second appraisal well, Hasdrubal-3, was drilled and flowed at the rate of 21 million square cubic feet a day (mmscfd). The third well, Hasdrubal-4, drilled in June 1998 flowed at the rate of 4.6mmscfd and 1,800 barrels of oil. In 2002, BG drilled the Hasdrubal South West-1 well which led to the discovery of light oil in the Tertiary El Garia formation. Drilled by the Key Manhattan rig, the well confirmed the presence of a southwest extension of the field.
Petrofac was awarded a front-end engineering and design contract for the field in October 2005. Conceptual and pre-FEED work was also carried out by Petrofac. The construction contract for the onshore gas plant was also won by Petrofac.
Hasdrubal A construction contract was awarded to Heerema Fabrication Group in November 2007. Heerema was responsible for engineering, procurement, transport, installation and commissioning of the platform. Saipem was responsible for manufacture, installation and pre-commissioning of the 110km offshore pipeline system from the field to the onshore terminal. Subsea Protection Systems was subcontracted by Saipem for concrete mattresses and dropped object protection covers for the project. Hallin Marine provided its Quasar ROV to Saipem to lay the pipeline under a US$1.3m contract. Quasar ROV was deployed from Saipem\'s VOS Sympathy vessel for the project. Scaldis-SMC was responsible for transportation and installation of the Hasdrubal platform. It used its Rambiz barge to transport all the components of the platform and install at the field.
