Identification of Oil Deposit Zones in Carbonates Fracture Wells

Abstract

For the integral evaluation of oil deposit are used some curves of geophysical well logs. In this article are considered in the well log analysis the following: spectral and natural gamma ray, resistivity, porosity, andformation microimager (FMI) operated in open hole, and other logs as the interpretation of mudlogging in relation with the evaluation of the more perspective hydrocarbons zones in oil deposit. Research wasbased in the integral analysis of one well show a zone of deposit between 3669 m - 3610 m with aninserting of little clay of 10 m. A second interval identified was of 3725 m -3670 m and it represents a deposit of quality best. The objective of this research is the identification of two oil deposit zones and detection of two intervals associating with different qualities, one of them with bad quality and fractures oriented with water in the well and a second interval with rocks of better properties for the oil deposit. Asresult of this research a production of 16m³/d of oil was observed in the well and for better results anincreasing of 60% of water cut was stimulated.
