Abstract

Single-point test results can be used to obtain information regarding the degree of damage in gas wells in the gas storage reservoirs. Single-point test is neither time-consuming nor costly to determine the productivity of a well. Furthermore, flow stabilization times would be short in high permeability gas storage reservoirs. Generally, a four-point test is conducted first to establish the deliverability relation. After some period of time, namely one year, a single-point test could be conducted. The results of the single-point and four-point tests can then be compared in order to identify any alteration in well performance.;The objective of this research is to develop a methodology to determine skin factor by using a single-point test. In this work, the impact of formation permeability on determination of skin factor is studied for two cases, including transient radial and linear flow. The impact of non-Darcy flow is also considered in these cases.;The results of this study are summarized by a series of correlation to evaluate skin factor from a single-point test.
