چکیده:

Identification and evaluation of producible zones is of major importance to the development of reservoir rocks. The Stoneley wave (or Tube wave) has been explored as a means of permeability estimation and evaluation.
Sonic measurements are sensitive to mobility and open fractures. Stoneley waveform from DSItool provides a direct and continuous fluid mobility estimation near the well bore (i.e., in the invaded zone). The KST curve can provide valuable information both for evaluation and production phases. This study shows that the methodology can be applied with success in carbonates with multiple pore types. The sequenceanalyzed consists of limestone and dolomite showing different grade of digenesis. The reservoir shows a high grade of heterogeneity withinconsistent porosity in the reservoir zone. The KST show good agreement with MDTand core analysis.
Potential applications of KST are formation evaluation, optimization of well production through betterplacement of the perforated intervals and planning to maximize hydrocarbon recovery. This technique provides fluid flow measurements before the completion and allows reservoir management to begin at earliest stages of a field’s development.
