New Well Architecture and Structural Modeling Based on the Integration of Seismic Data, Well Logs, Core, Production and Geomechanic Data in "Carito Field", Northern Monagas Basin, Venezuela

Abstract

Abstract Reservoirs at the Northern Monagas Basin, EasternVenezuela, are characterized by a very complex structural modelof sand-shale sequence (highly faulted system), as well as a diverse column of fluids, such as light oil, condensated, gas and water.Depths range within 15,000 to 17,000 feet.A preliminarily model was generated from surface seismic data before drilling, and was carefully evaluated and updated based on the information obtained from drilled wells. This paper presents an interesting case of design of new well architecture based on structural and reservoir re-interpretation of a block at Carito Field, after the integration of new 3D surface seismic data, Borehole seismic data (VSP), Crosswell seismic data and well logs (Images, Dip, Cross Dipole Acoustic logs), core and production data. The use of novel evaluation techniques of structural geology and reservoir were complemented with the geomechanical modeling of the area. The results of this integration are used for the design of new well geometry for the optimization of the drainage of reserves associated to this reservoir.
