Prediction of Final Temperature

PDF Version Also Available for Download.

Description

The engineering necessity of achieving maximum cooling of the borehole during drilling and logging operations on geothermal wells prohibits the determination of equilibrium temperature in the sub-surface before virtual rebound from the drilling disturbance some months after operations cease. Clearly, substantial economic benefits would accrue, in many cases, if a reasonable prediction of equilibrium temperature can be made while the rig is still over the borehole. The purpose of this brief report is to provide an abbreviated explanation of the physical principles of temperature rebound and provide a convenient plotting method similar to the Horner plot in order to standardize ... continued below

Description

The engineering necessity of achieving maximum cooling of the borehole during drilling and logging operations on geothermal wells prohibits the determination of equilibrium temperature in the sub-surface before virtual rebound from the drilling disturbance some months after operations cease. Clearly, substantial economic benefits would accrue, in many cases, if a reasonable prediction of equilibrium temperature can be made while the rig is still over the borehole. The purpose of this brief report is to provide an abbreviated explanation of the physical principles of temperature rebound and provide a convenient plotting method similar to the Horner plot in order to standardize temperature prediction in Geothermal Operations. It has the further purpose of outlining methods to determine an approximate thermal conductivity value for reservoir rocks and rebound times after drilling from the nature of the rebound curve. 2 refs., 2 figs.
