Oil Production in Offshore FieldsrAn Overview of the Brazilian Technology Development Program
Prospective studies point out that, in the short to medium-term, Brazil will incorporate 4 billion barrels to its proved reserves of heavy oil due to advancements in production techniques. As a result, Brazilian reserves of heavy oil will reach 7 billion barrels, taking more than 40％ share in the proven volumes. These figures do not account for the reserves of 2 billion barrels of extra-heavy oils that exist in the off-shore field of Membro Siri, Campos Basin. Advancements in heavy-oil production techniques certainly will match those numbers as they may unveil new scenarios and even bring closer the production onset of extra-heavy-oils from off-shore fields. Around the world heavy oil has been discovered when looking for conventional oil; and its reservoirs have generally been produced by applying the same techniques as those in the production of light oil. The predictable consequence is that the remaining resources associated with the conventional oils have a smaller participation in the available natural energy resources, increasing the importance of those resources associated with heavy oils. On the production side, in the world the percentage of heavy oils is now slightly over 10％; in Brazil the proportion is negligible. However, in order to assure the nowadays favorable demand-production relationship, the medium term perspective requires that the Brazilian share of such oils shall be above 20％ of the total produced volume. To accomplish with this number, the Brazilian Sectorial Fund for Research on Oil And Gas - CTPetro - has launched a Technology Development Program for Heavy Oil Production in Offshore Fields. The program focuses on the search of technological solutions supported by scientific knowledge to overcome the challenges associated with the exploitation of heavy oil reservoirs located offshore Brazil. Seeking to supplement the efforts of specific corporate programs, technical managers from oil companies and members of the academic community have been convened to propose prospective solutions and to set the priority for 40 previously selected projects. The present paper reveals, starting from the challenges posed by all branches of the exploitation area, following a six month work on interviews and document analysis, these projects and the actions envisioned to tackle them.
