<br />
<br />
<br />
As fluids move through a wellbore, there is transfer of heat between fluids and the earth due to the difference between fluid and geothermal temperatures. This type of heat transmission is involved in drilling and in all producing operations. This final project presents an approximate solution to the wellbore heat transmission problem involved in injection of hot fluids. The solution permits an estimation of the temperature of fluids, tubing, and casing as functions of depth and time. <br />

The solution assumes that heat transfer in the wellbore is steady-state, while heat transfer to the earth will be unsteady radial conduction. Allowance is made for heat resistances in the wellbore. The solution also describes the flow of heat from the formation interface to the earth in transient-heat conduction equation. |
