Determinación Analítica del Mecanismo de Empuje de los Reservorios del Bloque 15 Aplicando Balance de Materiales

Abstract

The knowledge of the drive mechanisms in a reservoir helps to understand the behavior of this, but it is necessary to update this information due to the dynamic nature of the reservoirs. The material balance technique allows updating and improving this information without the need for specialized software. This work presents the results of the application of the material balance technique to quantify the energy currently provided by each drive mechanism in the production of the reservoirs of the Fields belonging to Block 15; furthermore, a suitable method for the application of this technique is described. In the present work with the technique of material balance, the possible hydraulic communication between the reservoirs of two or more structures and the beginning of a slight depletion in two aquifers of the Block have been detected. In addition, the presence of aquifers in all the studied reservoirs was found, and each one adjusted to a theoretical model. In addition, the original oil in place has been determined with a minimum of deviation from the values of the volumetric method, and it was determined that the drive index due to the hydraulic thrust is greater than 90% in all the reservoirs studied.
