Transient, sandface temperature solutions for horizontal wells and fractured wells producing dry gas

摘要

Measured, bottom-hole transient temperature has been proven to be a valuable source of information. Similar to transient pressure (i.e. well testing) the temperature can also be used to estimate formation properties like permeability-thickness or to be used for flow rate allocation. Moreover, transient temperature has the unique advantages being sufficiently sensitive to identify the properties of the near-wellbore zone properties and/or the flowing fluid composition.
