Alternatives for optimization of the heavy oil production in onshore marginal fields in Brazil; Alternativas para otimizacao de producao de oleos pesados em campos marginais terrestres no Brasil

Abstract

The intention of this article is to present possible alternatives for optimization of the production of heavy oils in marginal onshore fields in Brazil. The use of gas micro-turbines, the application of SAGD (Steam Assisted Gravity Drainage), the use of the drilling technique for river crossing and to a proposal for a new system of the rig less workovers are approached. The focus is the search of the increment of the production, the increase of the factor of final recovery, the global reduction of the costs and the minimization of the environmental impacts. The volumes of heavy oils in Campos Basin and in national onshore areas they are significant and, therefore, techniques and procedures that optimize its production are strategic. In the Brazilian Northeast there are a series of small fields of low productivity, in general of heavy oils, some in production there are more than twenty years that need of a reduction of the cost for barrel to continue producing. A realistic and responsible posture with the use of probabilistics concepts, techniques of engineering of the reliability, adoption of 'tolerable' levels of risk (associate to the return), attendance on line of the sceneries, premises and criteria, (proposal of the  More>>
