Conversión de un pozo productor en inyector, mediante una gestión integrada de recursos

Abstract

The study was framed in determining the viability: technical, environmental and economic to convert the SAND-27 well from producer to injector, applying an integrated management of resources. The injection of water through this well is intended to increase the oil reserves in this area where the pressure drop has generated a decline in production. The development of this project has four stages of Management: the first a collection of information from the reservoir area and production facilities, the second stage a technical study to determine the oil recovered through the injection of water and the facilities associated with the recovery project. Followed as a third stage an administrative and human resources study focused on specifying the business group, planning, function manual and project organization. Finally, the fourth stage, assesses whether the execution of the project is feasible and profitable, analyzing the financial indicators: Net Present Value (NPV), Internal Rate of Return (IRR), Cost Benefit Ratio (RBC) and Period of Recovery of Capital (PRC). The management actions to be followed by the Project Manager for the Producer Well Conversion in Injector are described. The results of the injection of water from the SAND-27 well show a rupture time of 2,89 years in the initial stage (before the rupture), an incremental oil production of 335.075 Bls (recovery factor 2,1%), the subordinated stage (after the rupture) it is expected to recover 633.019 Bls (recovery factor 3,97%), in a time lapse of 9,1 years, total recovery factor by secondary recovery 6,08%, accumulated factor of recovery by Primary Recovery more Secondary 43%, the project has a useful life of 12 years of forecast. The economic-financial analysis indicates an initial investment of $ 3,737.913, the price is considered $ 32 per barrel of oil, a NPV of $ 2,164.528 is obtained; TIR of 29,75%; PRI of 39,2 months and RBC 1,22; this indicates that for every dollar invested $1,22 are recovered. A sensitivity analysis is carried out, considering the current price of oil in the market of $ 57, an optimistic value of $ 90 and finally a pessimistic stage of $ 28,10 to determine the breakeven point. All these factors show an investment project with high profit margin.
