地上生産データによるバックプレシャー式における指数nの算出

抄録

A method is presented for calculating an expornent n in the back pressure equation from wellhead production data. This method is based on the procedure developed by KATO (1987) and is expanded to the situation where turburent flow exists near wellbore. The study includes the effect of turburent flow to the estimation of the gas in-place and some sensitivities of variables to the proposed calcuation system.
