Estudio de factibilidad para desarrollar la zona sur oeste del campo Pucuna.

Abstract

The objective of this study was to analyze the feasibility of developing the South West zone of the Pucuna field, in order to promote the project to attract national and international investment. In fact, it is necessary to find new hydrocarbon accumulations since increasing production allows extending the useful life of the field, as conventional reservoirs are currently being depleted at an accelerated rate. This research starts with the description of the Palo Azul asset and shows general information about the Pucuna field such as: geophysics, structural geology, lithology of the main reservoirs, as well as its petrophysical properties. As a method to obtain referential data and make calculations for the South West zone, information from producer wells (neighbors) of the Pucuna field was used in an analogical way. This allowed estimating in the structure of interest, the Original Oil in Place (POES) in 22 MMBls, in addition to establishing 3 MMBls of reserves between the Napo "T", Napo "U", Hollin and Basal Tena sands. With the purpose of demonstrating the efficiency of the reservoirs to intervene, the productivity index and the recovery factor were determined, establishing that the Napo "T" and Napo "U" sands are the most productive, so they were chosen as main and secondary objectives, respectively. Therefore, it was established to drill 3 development wells type "S" and 1 advanced well type "J" and as artificial production system was designed for electrosubmersible pumps, incorporating 1920 BPPD of production. The investment required in the 4 proposed wells is $ 13,300,000, with revenues of $ 83,722,599.98 and expenses of $ 15,316,308. Finally, an NPV of $ 33,816,776 was obtained and an IRR of 59.87% for the "S" type wells and 45.43% for the "J" type well, since these values are within the range of acceptability in the economic analysis, it is concluded that the project is profitable.
