Venezuela Reservoir Optimization Conference, 1997

Discussion of geology, petroleum basins, and history of oil exploration in Venezuela.

A broad basin-to-basin overview and discussion of 12 reservoirs: Tia Juana (onshore and offshore), Lagunillas, Ceuta, Mara Oeste, Silvestre, Oveja, Santa Rosa, Carito, El Furrial, Pedernales, and Cerro Negro. Includes geographical and geological information, petrophysical and thermodynamic properties and drive mechanisms.

Risk analysis. Selection of fluids. Wellbore stability. Geosteering.

Logging while drilling and Platform Express logging services. Pressure gauge performance. Planning of wireline jobs.

NMR principles and petrophysics. Tar detection and permeability evaluation in North Monagas. Identification of gas and tar layers. Reservoir fluid sampling. Evaluation in the Orinoco Belt. Carbonates. Prediction of water cut. Identification of producible zones in wells drilled with oil-based mud. Continuous wireline fluorescence logging.

Saturation, porosity, and lithology evaluations through casing. Permeability and pressure. Production logging. Hydraulic integrity. Permanent monitor systems and how they can extend the life of a reservoir.

Methodology and practices for enhancing production. Identifying bypassed zones. Controlling water production and fines migration. Maximizing fracture conductivity and optimizing fracturing treatments. Customizing perforating programs.

Sedimentary analysis of sandstone reservoirs. Evaluation of fractured carbonates. Multioffset seismic profiles from old wells. Multiazimuthal walkaway VSPs. Reservoir descriptions around a horizontal well.
