Management of karst aquifers in coastal oil and gas fields: experiences in the northwestern hydrocarbon belt of Cuba

Main Article Content
Abstract
The main operational infrastructure of oil & gas E&p developed since the 1970´s is developed on the shallow coastal karst aquifers underlying the Heavy Crude Oil Belt of Northern Habana-Matanzas. Depending on its mineralization, these ground waters supplies domestic and municipal supplies, irrigation, husbandry and familiar agriculture and along the coastal ecotone, sun and beach tourism. This contribution describes the experiences and most important results of the regional water management comprising: a) the operation, since 1998, of a specific designed and constructed optimized ground water regime monitoring network of different physical, chemical, radiological parameters sampled at varied frequencies; b) development of innovative methods for the final disposal of produced waters; c) introduction of new non-conventional methods for oil and gas prospecting; d) application of specific measures for protection and sanitation of terrestrial waters; e) systematic joint use of geological, speleological, geophysical and geochemical (including isotope geology and hydrology techniques) and mathematical modelling for specific problems oriented to the delimitation of the local water systems and the characterization of the processes of mass transport.
