Models for geothermal wells [PDF]
, 1980 The problem of two-phase flow pressure loss is examined in order to give an answer to the problem of determination of the wellhead conditions. For this purpose two models have been developed, the first based on the pattern structure of the flow and the second on the mixing length theory.

Wellbore Storage Effects in Geothermal Wells [PDF]
Society of Petroleum Engineers Journal, 1980 Abstract The early-time response in the well testing of a homogeneous reservoir customarily is expected to give a unit slope when the logarithm of pressure is plotted vs. the logarithm of time. It is shown that this response is a special case and that another non-dimensional parameter must be defined to describe the set of curves that ...

, 2013 Geothermal well systems utilize the thermal energy of clean groundwater of hydraulically highly conductive aquifers with water tables close to the surface. The thermal energy of water produced from the well can be extracted by means of heat pumps. Such systems are also called two-well-systems, water–water-heat-pump-systems, or groundwater heat pump ...
