Resumo em Inglês
Once defined the thesis objectives and established its methodology, the work has begun, with an historical research of petroleum. A chapter about the petroleum crises in 1973 and 1979 was introduced. The foundation of CESP/IPT enterprise, its objectives, constitution, responsibilities and contracts signed with PETROBRAS were described. The work of PETROBRAS at Parana?s Basin, since PETROBRAS Foundation in 1953 through 1974, was showed. The picture 1 presents geological data of the work done by the enterprise, in the period of 1980, 81, 82. The seismic reflection results show Parana Basin?s viability, changing the old concept of low solution at this area. The geochemical analysis was done mainly in Ponta Grossa and Irati Formations. The drill engineering of the enterprise drilled 32 wells, without damaging or interrupting anyone, in a complex basin like Parana?s. The Drill Bit Program provided more efficiency in drilling. Air Drilling was tested and approved, first of all at Parana?s basin, to be used in solid formation like basalt and diabase. The Well Program Associated Services considered the Bit Program, the Well Logging and Formation Tests. Finally, the job included a Cuiaba Paulista Well?s report. At the conclusion, it was showed that the objectives were achieved.
