(Wydawnictwa AGH, 2017) Śliwa, Tomasz; Kowalski, Tomasz; Stryczek, Stanisław; Wiśniowski, Daniel; Bieda, Anna; Piwowarczyk, Sara; Beszłej, Jan; Naklicki, Mateusz; Sapińska-Śliwa, Aneta
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.

An analysis of the work conditions in the Bóbrka-Rogi field over the 100 year history of its exploitation
(Wydawnictwa AGH, 2017) Wojnar, Albin; Rybicki, Czesław
The Bóbrka - Rogi oil reservoir belongs to oldest reservoirs in Poland. The handmade well named Franek was created by Ignacy Lukasiewicz in 1853. It is currently the object about the historic museum. The accumulation appears in the anticline structure of the Bóbrka fold. As result of study of geological data, this fold has four secondary structures forming separate longitudinal blocks. Moreover transverse dislocations cross the Bóbrka structure on the row of separate deposits. Oil appears in four levels of Ciężkowice sandstones and in layers of the "czarnorzecki" sandstone. The level of the first Ciężkowice sandstone contains oil on the east from the Wietrznianka fault, II level of the Ciężkowice sandstone is oil-bearing within the Wietrznianka fault on the west, up to the Rogi fault on the east., III level of the Ciężkowice sandstone is oil-bearing from the Rogi fault on the east to the Bóbrka fault and partly outside it on the west, IV level of the Ciężkowice sandstone contains oil-bearing horizontals to the west from this block to the fault of the TPS mine. The sandstone Czarnorzecki contains oil-bearing horizontal to the west from the fault of the Jasiołka river. The reservoir belongs to the stratified type in the anticline structure it is shielded lithologically and partly tectonically by dislocations or overthrusts. As it gets out of data of geologically of deposit since the discovery of the deposit one got out of him above 1 200 thousand t of oil and 190 million nm3 gas. The surface of the mining district carries out approx. 2.5 km2 . Authors on the basis archival data made the analysis the previous exploitation this reservoir and the evaluation of perspectives of his continued existence with the regard of the possible revitalization of the wells.

Analysis and selection of $CO_{2}$ sources for CCS-EOR projects in oil fields clusters in Poland
(Wydawnictwa AGH, 2017) Mikołajczak, Edyta; Kosowski, Piotr; Stopa, Jerzy; Wartak, Joanna
Article contains detailed analysis and preliminary selection of potential $CO_{2}$ emitters, who could be suppliers of gas for CCS-EOR projects in oil fields clusters in Poland. The idea of $CO_{2}$ injection into clusters arises from the fact that oil reservoirs in Poland are relatively small, but very often located close together. Grouping reservoirs allows the potential storage capacity to increase significantly and improves economic indicators. In addition, CCS-EOR projects combine $CO_{2}$ storage (CCS) with an increase in production from mature oil fields (EOR). The analysis was performed using a database of carbon dioxide emitters in Poland, which was created by the National Centre for Emissions Management. This database contains a list of all registered producers of $CO_{2}$ with annual emissions exceeding 1 Mg. On this basis, potential sources of $CO_{2}$ for previously selected four clusters of oil reservoirs were chosen.

Analysis of energy transfer between pipes of U-type borehole heat exchanger
(Wydawnictwa AGH, 2017) Złotkowski, Albert; Druzgała, Angelika; Zeljaś, Dagmara
Use of low-temperature energy accumulated in the ground for heating buildings requires the borehole heat exchangers. The amount of heat exchanged (by the heat exchanger with the urethane) depends on the construction material parameters used to make the exchanger. One of the problems with the efficiency of the heat exchanger is the amount of heat transferred between the borehole pipes. This phenomenon can be described using numerical simulations or by studying a laboratory model. This article shows the results of laboratory measurements of the heat flux permeating between the pipes of the heat exchanger.

Determining the actual temperature of the side of a borehole heat exchanger
(Wydawnictwa AGH, 2017) Złotkowski, Albert; Druzgała, Angelika
Borehole heat exchangers (BHE) are made as hydraulic systems consolidated by cement slurry in boreholes. They mediate in heat exchange between the receiver on the surface (heat pump), and the reservoir of thermal energy (rock mass). In the analytical description of temperature changes accompanying energy download and return to the rock mass, the temperature of the entire borehole heat exchanger is assumed to be the same. In fact, the exchanger temperature changes both in the vertical and horizontal cross-sectional view of the exchanger. Accordingly, the temperature of the interface of the hardened cement slurry and the rock mass differs from the one which was adopted for design calculations. The article shows the differences between the theoretical and actual state, when the temperature was measured with a thermal imaging camera. It also includes suggestions regarding the mathematical description of temperature changes on the side surface of the heat exchanger. Measurements were made by a model of a BHE equipped with a single U-tube.

Remarks on the possibility of applying the mercury porosimetry method in petrophysical studies of rocks
(Wydawnictwa AGH, 2017) Maruta, Michał; Kulinič, Vitalij
Rock pore space is a rock mass composed of a large number of irregularly arranged and shaped pores. The diameter of the pores and their distribution and tortuosity determine the possibility of collecting and conducting reservoir fluids (Oil, Natural Gas and Saline water). Characterization of the pore space is intended to determine the distribution and size of the cavities in the rock. The characteristics of the study is based on parameters such as porosity and permeability and upon which the petrophysical static model is built. The article discusses methods of mercury porosimetry from the aspect of the exploration of the pore space of reservoir rocks for hydrocarbons. The research results of the petrophysical parameters of samples similar to typical reservoir rocks and unconventional rocks were presented. The results of capillary pressure tests in graphic form for six samples of the Inoceramian sandstone of the Skole unit were also given. The results of the petrophysical studies show the limitations of the use of the mercury porosimetry method in investigations of low reservoir parameters. Therefore, the authors have identified the next stage of research as exploring the application of the helium porosimetry method due to the chemical neutrality of helium and its small particle size.

The development of a sensor system for monitoring the displacement of horizontal laterals in Radial Drilling Technology
(Wydawnictwa AGH, 2017) Ziaja, Jan; Movčan, Vasil'
Radial drilling technology was developed by Rad Tech international inc., an American company set up by Henk Jelsma, its permanent head and the technology patent holder. First introduced in the Americas, radial drilling technology acquired wide recognition in the USA and Colombia and later found applications in Canada, Bolivia, Argentina, Chile and the Middle East. In general, this technology is aimed at extending and improving drainage areas in productive formations. Other applications of radial drilling include the creation of specifically directed injection channels and exploration activities. Performance testing of these short radius laterals has not been adequately studied and significant questions remain about how well these technologies can deliver on their promises. The main objective of the paper is to sum up previous experience in developing a system for monitoring the displacement of horizontal laterals and wells, and examining a prospective new technology which can increase the efficiency of radial drilling.

Analysis of the participation of various components in natural gas transport
(Wydawnictwa AGH, 2017) Apostol, Rostislav; Kowalski, Rafał; Liszka, Krystian; Łaciak, Mariusz; Olìjnik, Andrìj; Szurlej, Adam
Natural gas is a mixture of hydrocarbons with combustible methane as the main component, the content of which usually exceeds 90%. Among the remaining components of natural gas are ethane, propane, butane, nitrogen, carbon dioxide and sulfur compounds. Helium can be also found in some natural gas fields. The composition of natural gas depends on, e.g. the field from which the gas comes, and also way in which it is transported, i.e. pipelines, LNG technology. The quality of natural gas is regulated by respective standards. Gas transmission pipelines are the most popular and dominant method of gas transport on the international gas market, though LNG technology has recently started to play an increasingly prominent role. The intensive development of renewable energy sources is accompanied by the development of the Power to gas technology - the electric energy excess is used for the hydrogen production, which can be directed to the existing natural gas network and such a mixture of natural gas and nitrogen is transmitted. At present, transmission pipelines for nitride natural gas Ls and Lw exist in Poland. The aim of this paper is to analyze the influence of natural gas admixtures on the operational parameters of transmission pipelines.

The influence of borehole design on the production and efficiency parameters of wells intaking Quaternary waters in the south of Łódź
(Wydawnictwa AGH, 2017) Macuda, Jan; Styrkowiec, Ewa
Quaternary wellbores are very liable to rapid drops of hydraulic efficiency mainly caused by clogging processes and the corrosion of the wellbore structure. The presence of such processes and their intensity largely depend on the hydrogeochemical conditions of the intaken aquifer and also the production rate and extraction method of a given wellbore. Among the major factors slowing down the hydraulic intensity are a correctly designed well, especially the properly selected type and design of the filter. A well designed wellbore filter should have low hydraulic resistance of the inflowing water and be resistant to clogging and corrosion in the given hydrochemical conditions. This allows for long and failure-free extraction of large high-production wells. The results of analyses of the effect of intake wellbore design on its hydraulic efficiency are presented in the paper. The intake wells producing Quaternary waters for waterworks in the southern part of Łódź were analyzed.

The multicriteria method for selecting rigs for drilling gas wells from post-mining gobs
(Wydawnictwa AGH, 2017) Macuda, Jan; Łukańko, Łukasz; Hendel, Jacek
During drilling wellbores from the surface to recover methane from post-extraction gobs, attention should be paid to using appropriate rigs. Rigs with optimum technological parameters, adjusted to the geological setting, design of wellbore and technology of drilling, allow for high drilling rates and a considerably lower cost of realization to be obtained. The rig to be used for drilling production wells can be correctly selected using the multicriteria optimization method with synthetic evaluation measure of its technological parameters. For this purpose, the technological parameters of rigs available on the Polish market for the realization of normal diameter wells with percussion-rotary method to a depth of 500 m and 1000 m were reviewed. Taking into account the geological build of the Upper Silesian area and the design of the producing well used for the production of methane from past-extraction gobs, eight evaluation criteria and their weights (W) were selected. On this basis the technical parameters of rigs to be used for drilling wells to a depth of 500 m and 1000 m were reviewed with the multicriteria method. This created the basis for selecting dedicated rigs with optimum technological parameters for drilling normal diameter wells to a depth of 500 m and 1000 m.
