Evaluación Técnica de Facilidades para Recuperación Secundaria en los pozos Atacapi 12 y 13 del bloque 57

Abstract

In this work, the currently installed water injection system was evaluated, which consists of transfer pumps PCF-1440 and PCF-1441, flow lines and horizontal multistage pumps PCF-1438 and PCF1437, which transport the water to be injected into wells ATC 12 and ATC 13. For this evaluation the use of the equations involved in the flow losses and sizing of pumps was considered, together with the applicable standards within the process (ASME B31.3). The results obtained from the basic equations were compared with the results obtained from a free access process simulator "DWSIM". Once the dimensioning was determined and considering the operating conditions, the risk analysis was performed under the "WHAT IF" methodology, for the simplicity of the system, complemented with the economic analysis of the implementation of the secondary recovery project and its feasibility. As a result it was obtained that the diameter of the pipe (6 in) is oversized considering the maximum flow rates, it is concluded from the economic analysis that the injection costs per barrel of water injected must not exceed $ 2.30. It is recommended from the analysis "What If" to consider in case of going from pilot project of injection to a continuous injection to implement pumps of back up in the units of pumping of high pressure, by operational reliability.
