Saragossa Plantation is located in Natchez, Mississippi. It was established in 1823 by one of the wealthiest cotton planters in the Old South, Stephen Duncan. Between 1823 and 1865, Saragossa was home to numerous enslaved African Americans who faced dangers of abuse at the hands of their overseer, sundered and reconstituted families, disease, overwork, and lack of autonomy. Hunting by members of the slave community is suggested as one of the more effective mechanisms for coping with meager rations, but it also functioned to reinforce male gender identity and to incorporate strangers into the quarter community. Overall, hunting strengthened slave family and community bonds and made these social institutions better able to cope with violence, lack of autonomy, and other risks faced by slaves.

A critical part of the redevelopment plan for Dacion Field is to optimize depletion of the middle sands. To help develop a strategy for this, four geological models were built, upscaled, and numerically simulated. The models were constructed for the L2U-M2 and the P1-R0 intervals in both East Dacion and West Dacion. The deterministic framework for each geological model was built using a 3D seismic survey and wireline log correlations. Several techniques were used to distribute model properties including object modeling for facies bodies, sequential Gaussian simulation for porosity, a poroperm cross-plot for permeability and height vs. saturation curves for water saturations. Multiple realizations were generated for each of the four models and streamline modeling was used to identify key realizations with differing amounts of heterogeneity. These were then scaled-up and numerically simulated. The realization achieving the closest match to overall reservoir performance was chosen for detailed well history matching. The detailed history matches were optimized by modifying permeability/transmissibility values and relative permeability curves. Subsequent forecast runs identified 54 new well locations and showed that incremental recoveries of 6 to 18 percent of OOIP are possible through a combination of infill drilling, water injection, and the commingling of production. The simulations proved very useful for developing strategies to optimize production, but recent drilling indicates that the models were not very successful in predicting the performance of new wells on an individual well basis. The key reasons for this arethe distribution and connectivity of sand bodies in the models are different than those in the reservoirs, andthe data and analysis tools used in the modeling work need improvement. Introduction The Dacion Field is located in the Oficina Basin of Eastern Venezuela and consists of two separate accumulations: East and West Dacion (Figure 1). Dacion Field is part of the Dacion Block which also contains Levas, Ganso, and a number of smaller accumulations. Dacion Field originally contained about 1,700 MMBO of oil-in-place and began production more than 50 years ago. Production peaked at 45,000 BOPD in 1958, but by early 1998 rates had fallen to less than 8,000 BOPD with a cumulative production of 260 MMBO. In April, 1998, Lasmo Venezuela (ENI) and PDVSA began a redevelopment project in Dacion as part of the third Venezuelan licensing round. Infill drilling and workovers were initiated along with the installation of new facilities capable of handling 70,000 BOPD. The primary objective of the project is to increase production and reserves from thick, areally extensive sandstones which were previously shut-in at water cuts of 60–70%. A secondary objective is to increase oil production from thinner, more discontinuous sandstones through a combination of drilling, recompletions, and waterflooding.
