Opis:: The use of suitable materials for the preparation of sealing grout is an important issue from the point of view of the correct construction of borehole heat exchangers and geothermal wells. The minimization of the loss of heat during the transport of thermal water in geothermal wells can be achieved by use of sealing slurries with reduced thermal conductivity. Such slurries are also recommended in the upper part of deep borehole heat exchangers and the upper part of energy piles. The publication describes the impact of the addition of diatomite as a material lowering the thermal conductivity of solidified grout.

Tematy:: graphite
thermal conductivity
geothermal energy
Opis:: The fast development of low-temperature geothermal energy affects the search for newer and newer solutions and materials used in the construction of borehole heat exchangers. One of the most important factors affecting the correct operation of heat pump systems with borehole heat exchangers is appropriately selected solidified grout. Solidifies grout has to be characterized by the highest thermal conductivity and good sealing borehole heat exchangers. The paper will present the impact of graphite on the thermal conductivity of solidified grout.

Tematy:: drillability

MSE
Opis:: The advancements in drilling have always depended on the cost of drilling of new wellbores, therefore mathematical models of the drilling process were elaborated to minimize the cost. The first simple models based on a few fundamental parameters, were then developed into complex, computer-based models employing many variables. Models made for cutter bits are used for PDC tools. They contain formulae accounting for drilling parameters and wearing of the bit. The paper addresses works which prove that in some particular situations the influence of the tools wear on the drop of rate of penetration can be neglected, thanks to which simple formulae are obtained, based on the fundamental parameters and which are easily applicable in the field conditions. The MSE is an amount of energy used for drilling a given volume of rock. This approach is useful and practicable because allows for detecting possible inefficiencies in a relatively short time (as compared to other parameters). Attempts are made to compare the drillability indications ZSP with MSE plots, thanks to which new conclusions and observations can be drawn as far as the analysis and interpretation of drillability plots is concerned.

LST
Opis:: This paper shows research of Linear Swelling Test (LST) of shale rocks under the influence of three drilling muds with different cationic polymers. Tested polymers have been synthetized at the Drilling, Oil and Gas Faculty of AGH UST Krakow. Research findings indicate that synthesized polymers as well as developed on its base drilling fluids effectively inhibit hydration and prevent the disintegration of clay formation.
