Oil-field is not just a compendium of oil wells; it is a small habitat, a city in itself. All the byproducts produced during refining process are not useful. A typical practice has been to dump the waste products to some far off land fill, a practice that is environmentally hazardous. This necessitate oil field waste disposal program and procedures. Informational efforts educated businesses about oil fields, waste products generated and their types.
Every oil reserve has several layers of naturally occurring water and hydrocarbons. Its segregation requires large amounts of seawater to be poured in so as to effectively separate them. This contaminates underground water. This is just one difficulty besides others like refinery waste management, cleaning the oil-tanks and response in the event of a spill.
Lula Oil Field, Brazil’s first supergiant oil field, was described as “the second independence of Brazil” by the former Brazilian president Luiz Inácio Lula da Silva. Estimated to include a total recoverable volume of 8.3 billion boe, the pre-salt carbonate reservoir is 250km off the southeast coast of Rio de Janeiro, beneath 2126m (6975ft) of water and 2791m (9156ft) of soil, rock and salt. Developing the field required many challenge to be rise above, some of which were included in a presentation covering the Lula Nordeste (NE) pilot project at the 2016 Offshore Technology Conference (OTC) in Houston.
- 2006 – Tupi oil field discovered
- 2008 – Aker Solutions awarded a contract to supply the first set of subsea trees
- 2009 – First pilot production from Cidade de São Vicente FPSO
- 2010 – Tupi was declared commercial and changed its name to the Lula Oil Field
- 2011 – The Lula-Mexilhão Gas Pipeline entered service
- 2012 – Sembcorp Marine awarded FPSO contract
- 2014 – Cidade De Mangaratiba FPSO commissioned
- 2015 – Cidade De Itaguai MV26 FPSO arrives on field
- 2016 – Cidade De Marica and Cidade De Saquarema FPSOs commissioned
According to the OTC presentation, Lula would be industrial in phases, a strategy familiar to Petrobras, which would allow the learnings to be applied on future projects, progressively reducing risk. In the first phase, static and dynamic reservoir data would be collected through appraisal and reservoir data acquisition wells, drill stem tests (DSTs), extended well tests (EWTs) and pilots systems. Using this data, phase two would initially see definitive production systems put in place and later followed by new technologies to enhance production.
Santos Basin is the largest offshore sedimentary basin in Brazil, ranging for a total area of over 350,000 square kilometers, all the way from Cabo Frio (state of Rio de Janeiro) to Florianópolis (state of Santa Catarina).
- Lula Oil Field Location: Located in the Santos Basin, 250 kilometres (160 mi) off the coast of Rio de Janeiro, Brazil.
- Lula Oil Field Owners: Owned by Petrobras with controlling 65% of the stake while BG Group holds a 25% and Galp Energia holds 10% of the share.
- Lula Oil Field Companies: Operated by Petrobras
- Lula Oil Field Recoverable Reserves: Contains at least 5 billion barrels (0.79 km3) of recoverable oil which could increase Brazil’s reserves by 62%.
