... storage. These tests were often misinterpreted as channel or radial composite reservoir models, leading to incorrect reservoir parameter estimation and, lately, in unsuccessful remedial work. Tests performed with downhole shut-in and no annular communication showed, in most cases, constant wellbore...

... responses were plotted. Sensitivity analysis shows that the pressure responses for both Darcy flow and non-Darcy flow conditions are the same for the following parameters: wellbore storage, skin factor, ratio of storativity, and interporosity flow coefficient. Non-Darcy flow mainly affects the transition...

... to calibrate and validate the analytical model. TDS technique is also used to analyze the linear and pseudo-radial flow regimes in order to find fracture length, fracture conductivity and several conventional reservoir parameters, e.g. permeability, wellbore storage and skin factor. Multiple fractures create...

Under these conditions the use of a numerical model, with options for undulating well architectures, will be necessary for accurate analysis of pressure transient data. flow regime pressure transient behaviour...

Abstract Wellbore storage, short producing times and variable rate effects usually make the identification...

... by the effect of wellbore storage. The general practice in such cases is to evaluate the time to the end of wellbore storage in a horizontal well using infinite conductivity fracture solutions. In this paper, a new, semi-analytical solution is developed to account for wellbore storage and skin effects...
