Estudio técnico de la implementación de fracturamiento hidráulico en pozos productores del Campo VHR

Abstract

This study analyzes the results obtained from the application of hydraulic fracturing that was carried out in producing wells of the VHR Field during the years 2018 and 2019. Of the five wells that were stimulated, the study was carried out based on the wells VHR-8 and VHR-13, which were hydraulically fractured during these years.

The analysis allowed to conclude that the fracturing work carried out in the two wells was successful. The comprehensive and comparative study of before and after each well, allowed to corroborate that for well VHR-08 it was obtained: a very desirable fracture geometry, the skin after stimulation was reduced from S = 0.28 to S = -5.95, With a characteristic flow efficiency in fractured wells of EF = 3.26, the supply in the IPR curve presented a substantial increase in its maximum flow reaching 1462 bls / day and an oil production with stabilized production intervals between 150 and 140 BPPD. For its part, the well VHR-13 presented a reduction in its skin of around 71%, a flow efficiency of EF = 1.54, a notable improvement in its supply with 2886 bls / day compared to the 963 bls / day prior to its fractured and increased its oil production reaching +/- 300 BPPD.
