Basic concepts and gas flow equations

Section 1 of “basic concepts” illustrates the meanings of various concepts commonly met when doing well test analysis, the occurring geological conditions, and the characteristics on well test interpretation type curves of various flows. This is the main basis of “graphical analysis method” introduced in <a class="cLink" queryStr="?_fmt=high&_origin=article&_docanchor=defaultINDEX_LINK_ANCHORm for these engineers, this basic knowledge about flow equations is really necessary.
