RESUMO:

Petrobras and other oil Companies have developed activities of exploration and production of oil and natural gas in the Potiguar Basin for more than 40 years, interacting with the groundwater. Thus, it becomes increasingly important and necessary, the implementation of a monitoring plan and management of aquifers based on hydrogeological controls identified.The objective of this study is a proposal of a hydrogeological model for the area of Fazenda Belém, in the State of Ceará, focusing on the relationships of hydraulic loads of water systems and its implications in chemistry and management of groundwater in the area of Fazenda Belém. A conceptual hydrogeological model for the Açu-Barreiras-Jandaíra aquifer system, in its original condition, before to the interference of the oil exploration activity, was defined. Based on the historical data of hydrodynamics and hydrochemistry were established the corresponding relations between the aquifer units. The results of hydrodynamic loads and chemistry parameters of aquifers, obtained from the data file of Petrobras and some government agencies, were interpreted and then, evaluated the possible modifications in the quality and quantity of groundwater, mainly due to anthropogenic activity and capture of groundwater.       The study did not identify any significant change in the chemistry parameters of the aquifers, however, a significant depletion of the potentiometric surface of the Açu aquifer, was identified, specifically in the area of Fazenda Belém., This situation suggests that is necessary to propose measures of control, through the continuous monitoring of the aquifer water levels and water quality.
