Correction of vertical permeability estimated by horizontal-well pressure transient test analysis

Different data are required in order to establish a realistic reservoir model capable of predicting the dynamic field behaviour during the development stage of an oil field. Well testing is considered to be one of the most effective methods for obtaining these reservoir and wellbore data. Numerous analytical models are available and utilised in investigating vertical-well pressure transient tests, on the other hand, horizontal-well pressure transient tests have been considered as more difficult to analyse. In this work, well test data of a horizontal-well are simulated for homogeneous isotropic and anisotropic reservoirs and analysed in order to develop empirical correlations that rectify the vertical reservoir permeability estimated by well testing.
