Sequence Stratigraphy and Sedimentological Model of Barúa Field Reservoirs Eocene Misoa and Pauji Formations Lake Maracaibo Venezuela

摘要

This paper presents the sedimentological and stratigraphicalrnmodel for the Eocene section of Barúa Field, MaracaibornBasin, Venezuela (Fig 1). The main reservoir units arerncomprised at the base by the Upper Misoa sands (B-0/B-1) andrnat the top by the basal Paují sands (A-9/A-10).rnThe objective of this study was to establish and predict therngeometry, distribution and physical reservoir quality of thernflow units in order to implement a viable economicrnexploitation plan.rnHydrocarbon extraction in the Barúa field began in 1957 afterrnthe successful drilling of well MGB-1x. This field isrnproducing 16 MB/D, and has so far reached a cumulativernproduction of 83.3 MMB. The estimated OOIP is 1.4 MMMBrnand total remaining reserves are in the order of 226.7 MMB.
