A Gas Correction for the Separator Method Used in Geothermal Well Testing

Abstract

A geothermal well can be tested for its performance by using several methods, one of them is known as separator method. This method usee a pressure separator to separate vapour and liquid phases of the geothermal f l u i d , after wbich flowrate of each phases are measured separately. The vapour phase of the f l u i d consirts not only of steam but also of gases, The presence of these gases i n steam, which may have concentrations ranging from t o or 30% by weight, is usually ignored the flowrate Later on this results coald cause some i n designing the power plant because the designing engineers need t o have precise data about the of the well. using the gas data obtained from chemical analysis of gas taken during tbe period of well tetting, it is now possible to rake correction for the separator method used i n geothermal well testing.
