The Orinoco Oil Belt (OOB) as a principal oil reservoir in the world mark a milestone in new technologies and innovation, this situation let us affront all inherent challenges and improve the productivity in this important zone. The study was designed in order to asset increase in the production levels for horizontal wells, this specific type of wells represent most important support of production in Petro San Félix company operations. However, they are suffering an important reduction of production for natural declining factors and damage at liner face or well down area. The methodology was based in a selection of better candidates under technical and economic considerations, these opportunities was included in the evaluation matrix, measured and compared to rank best options to work. In each case, geological properties and dynamics flow in the well was determining in the kind of treatment to use. The methodology has been reviewed with statistical results in order to include this feedback and improve it with the state of art. Results for this procedure include 80 candidates wells basket. After 7 months activities, have been worked 38 wells and production increase of 1812 barrels per day. Methodology could be used as model in other areas around Orinoco Oil Belt, because the applicability and economics was demonstrated in the Petro San Félix simple used for this study.

The new developments of extra heavy crude oil in Orinoco Oil Belt (OOB) will have to affront important challenges. Assuring the resource extraction without impact negatively the original environment will be the most important investment in these remote areas. Restricted access due topographical irregularities, environmental restrictions and lack of production facilities are typical problems in new exploitation OOB areas. The study is based on the technical and economic viability evaluation for the development of new opportunities in Zuata Field; considering volumetric milestones for next 6 years, the new areas and thermal projects represent the most important production booster. Using diagnostic and planning resources as probabilistic analysis, economic evaluations, geologic configurations, possible projected sceneries were obtained to find solutions, in order to achieve the best cost-benefits relationship in exploitation schemes for new fields. As principal results we can mention: - Most optimistic probabilistic prediction allows drilling 36 wells per year. This scheme represents an accumulate increase of 53724 b/d in six years. - Less optimistic probabilistic prediction allows drilling 16 wells per year. This scheme represents an accumulate increase of 35904 b/d in six years. - Six-year field development contemplating temporal facilities is not technically viable. - Data acquisition strategies, focus in decreasing the uncertainty in the geological model must be taken into account in the aggressive exploitation schemes. The results of this study could be used as a decision support and background for others similar business in Orinoco Oil Belt. Since all new ventures are looking for earlier solutions in order to reduce costs and improves profits without having a negative incidence on the environment and the reservoir properties.

El plan de delineación de un yacimiento a partir de la perforación de pozos estratigráficos es una etapa crucial al inicio de cualquier campo productor de petróleo, de esto depende su optima explotación garantizando una mayor cantidad de reservas recuperables durante la vida productiva, ejecutando una menor inversión. Sin embargo, la necesidad de incrementar la tasa interna de retorno para cubrir los gastos operacionales y auto sustentar la inversión, hace que se inicie la etapa de producción sin tener modelos robustos del subsuelo, tal y como es el caso de las empresas conocidas como nuevos desarrollos de la FPO, en las cuales se comienza a desarrollar, a priori, un área determinada del campo conocida como Producción Temprana Acelerada (PTA). El objetivo de este trabajo es mostrar una manera óptima de seleccionar una secuencia de perforación de pozos estratigráficos, 10 en este caso, mediante la evaluación y el análisis de un parámetro calculado denominado índice de oportunidad (IO), que incluye tantas propiedades petrofísicas de las rocas, respectividad de los sub-miembros e índice de incertidumbre. Esta metodología permitió jerarquizar la perforación de las localizaciones según la oportunidad que tengan de encontrar arenas productoras y su ubicación en el campo respecto a la data ya adquirida, obteniendo con esto una secuencia donde prevalecen los pozos que aportarán rápidamente mejor calidad y mayor cantidad de información para la explotación de los yacimientos, trabajando paralelamente la delineación como la producción del mismo, rompiendo el esquema tradicional donde el principal parámetro para iniciar la captura de información es la zona con mayor incertidumbre
