Abstract

The main issue in conducting well tests in horizontal wells involves challenges in determination of late radial flow using pressure transient technique and, consequently, accuracy of reservoir data and well parameters. Oil production losses during longer shutdown periods for pressure build-up analysis should also be noted. The paper present the results obtained from interpretation of production decline curves of horizontal oilproduction wells (long-term bottomhole pressures and production data) used to determine reservoir flow properties and well parameters. These results are compared with interpreted pressure build-up test data. Conclusions on the applicability and further advancement opportunities of this method are made.

Key words:

well testing, pressure build-up curve, production data analysis, pressure curves, horizontal oil wells.
