Discharge Analysis of Well 9 in Reykjanes Field, Iceland

Abstract

A discharge analysis method is presented in terms of three key elements: two-phase flow wellbore simulator, reservoir productivity index, and wellbore pivot point based on pressure surveys. The evaluation and production testing of 9 in the Reykjanes high-temperature fleld in Iceland, are reported and discussed. The output of this well was measured at wellhead pressure of 20 bar-g. The main feedzone of the well was found to be in the depth range 1340-1350 The mperature of the inflow brine similar to seawater in corn osition was determined in the range 280-290 Calculations showed that the well's deliverability depends greatly on the wellbore diameter. and the enthalpy of the steam-brine mixture.
