Deep Borehole Heat Exchangers — A Conceptual and Comparative Review
Borehole heat exchangers (BHEs) are used for transforming a rock mass into an underground heat storage. Usually, their depth does not exceed 200m, but some extend to a depth of almost 3000m.
CHARACTERIZATION OF CHEMICAL, MINERAL AND RHEOLOGICAL PROPERTIES OF OIL-POLLUTED DRILLING WASTES AND THEIR DETOXICATION *
mineralogical (XRD, FTIR, SEM) and rheological investigations of oil-polluted, spent drilling muds were carried out. The muds represent polydispersive, colloidal, mineral-organic systems with
Theoretical model of borehole heat exchanger
The paper deals with the possible use of existing oil wells for geothermal energy production. A mathematical model, describing the process of exploitation of a borehole heat exchanger, has been
An analysis of the numerical model influence on the ground temperature profile determination
The estimation of the ground temperature profile with respect to the depth and time is the key issue in many engineering applications which use the ground as a source of thermal energy. In the
Deep Borehole Heat Exchangers - A Conceptual Review
Borehole heat exchangers are used for transforming a rock mass into an underground heat storage. Usually, their depth does not exceed 200 m, but some extend to a depth of almost 3000 m. Underground
The influence of time of rheological parameters of fresh cement slurries
sealing of casing pipes in deep wells and the rock mass with borehole injection methods, the rheological parameters of sealing slurries should be selected depending on [1,2]: reservoir conditions of
A New Method Based on Thermal Response Tests for Determining Effective Thermal Conductivity and Borehole Resistivity for Borehole Heat Exchangers
Research on borehole heat exchangers is described on the development of a method for the determination, based on thermal response tests, of the effective thermal conductivity and the thermal
Influence of bentonite addition on parameters of fresh and hardened cement slurry
* Oil and Gas Institute – National Research Institute ** AGH University of Science and Technology *** Paper realized on the basis of the research work Analysis of possibility of improving the
Characterization, properties and microstructure of spent drilling mud from the point of view of environmental protection
Dynamic advances in the drilling technology applied to prospecting for oil and gas deposits are associated with growing volumes of drilling waste. The waste materials of this origin can be divided
