Previous issue date: 2015-09-29 / Nos ?ltimos dezesseis anos surgiu no Brasil um segmento de produtores independentes com
foco de atua??o nas bacias terrestres e de ?guas rasas. Entre os desafios destas empresas se
encontra o desenvolvimento de campos com projetos com um valor presente l?quido (VPL)
baixo. O objetivo deste trabalho foi estudar a melhor op??o t?cnico-econ?mica de
desenvolvimento de um campo de petr?leo no Nordeste Brasileiro aplicando a simula??o de
reservat?rios. A partir de dados reais de geologia, reservat?rios e produ??o foi realizado o
modelo geol?gico e de simula??o. Devido a n?o ter an?lise PVT, foram utilizados os dados do
ensaio de destila??o denominado Pontos de Ebuli??o Verdadeiros (PEV) para criar um
modelo de fluidos gerando as curvas PVT. Ap?s realizado o ajuste manual do hist?rico, foram
simulados quatro cen?rios de desenvolvimento: a extrapola??o de produ??o sem novos
investimentos, a convers?o de um po?o produtor para inje??o de g?s imisc?vel, a perfura??o
de um po?o vertical e a perfura??o de um po?o horizontal. Como resultados, do ponto de vista
financeiro, a inje??o de g?s foi a alternativa com menor valor agregado, podendo ser vi?vel
caso haja restri??es ambientais ou regulat?rias de queima ou de ventila??o ao meio ambiente
do g?s produzido do campo ou de campos vizinhos. O fator de recupera??o atingido com a
perfura??o dos po?os vertical e horizontal ? similar, mas a perfura??o do po?o horizontal ? um
projeto de acelera??o de produ??o, portanto a produ??o acumulada incremental atualizada
com uma taxa m?nima de atratividade da empresa ? maior. A depender do pre?o do barril de
petr?leo Brent e do custo de perfura??o esta op??o pode ser t?cnica e financeiramente vi?vel. / In the last 16 years emerged in Brazil a segment of independent producers with focus on
onshore basins and shallow waters. Among the challenges of these companies is the
development of fields with projects with a low net present value (NPV). The objective of this
work was to study the technical-economical best option to develop an oil field in the Brazilian
Northeast using reservoir simulation. Real geology, reservoir and production data was used to
build the geological and simulation model. Due to not having PVT analysis, distillation
method test data known as the true boiling points (TBP) were used to create a fluids model
generating the PVT data. After execution of the history match, four development scenarios
were simulated: the extrapolation of production without new investments, the conversion of a
producing well for immiscible gas injection, the drilling of a vertical well and the drilling of a
horizontal well. As a result, from the financial point of view, the gas injection is the
alternative with lower added value, but it may be viable if there are environmental or
regulatory restrictions to flaring or venting the produced gas into the atmosphere from this
field or neighboring accumulations. The recovery factor achieved with the drilling of vertical
and horizontal wells is similar, but the horizontal well is a project of production acceleration;
therefore, the present incremental cumulative production with a minimum rate of company's
attractiveness is higher. Depending on the crude oil Brent price and the drilling cost, this
option can be technically and financially viable.
