ABSTRACT
As fluids move through a wellbore, there is a transfer of heat between the fluids and the earth due to the difference between the fluids and the geothermal temperatures. This type of heat transmission is involved in drilling and all producing operations. H. J. Ramey developed in 1962 an approach of solution which investigated the wellbore heat transmission to provide engineering methods useful in production and injection operations. Nowadays the energy production in the case of the renewable energies particularly in the case of the geothermal energy, which has generated a considerable interest the past few years , we need not only quantitative but qualitative knowledge of wellbore heat transfer too with the invention of computer technologies. This study, which presents a simple mathematical estimation of the temperature of produced geothermal hot water, is the refinements of the so-called Ramey-theory. The solution supposes that the heat transfer in the wellbore is steady-state, while the transfer to the earth is unsteady radial conduction. Fields and calculated results of Hungarian production wells of Zsori-4 and Bogács (4-17) , are presented and analyzed to establish the appropriateness and the usefulness of the study.
