Beziłowa płuczka wiertnicza przeznaczona do wierceń HDD na bazie nowego polimeru PT-51
(2010) Chlebosz, Robert; Fabia, Bogusława; Wysocki, Sławomir
Horizontal directional drilling are more often used in engineer practice. They have to improve living standard by allowing electricity, fuel and information transport and by building municipal water supply systems. When the ground methods are too expensive, or impossible the underground installations will be perfect solution. They enable to avoid easily the obstacles such as: roads, buildings or even rivers. The drilling muds are one of the most important elements of HDD technology. Choosing optimal mud system help maximalize drilling progress and minimalize risk of investment. The article presents results of research into drilling mud for HDD method with the addition of new polymer PT-51 modified by CO-3 ions. It was also tested against salt monovalent and bivalent contamination, the temperature resistance and lubricity. The results show that composed mud can be applicable in the industry.
Analiza zmian przepuszczalności skal dolomitu głównego w strefie przyotworowej na podstawie wyników opróbowania rurowym próbnikiem złoża
(2010) Dubiel, Stanisław; Wojnarowski, Paweł; Pyrzak, Paweł
The geologic and reservoir conditions in the Main Dolomite strata of the Polish Lowland as well as their influence on the drilling up conditions and testing of the productive horizon are discussed in the paper with special emphasis on disturbed permeability of rocks in the well zone. The changes of Main Dolomite permeability were analyzed on the basis of the DST DG-2 results. The radius of the well zone of lowered permeability of reservoir rocks was determined.
Ocena efektywności stosowania wybranych metod wtórnych i trzecich eksploatacji ropy naftowej z wykorzystaniem symulacji komputerowej
(2010) Wojnarowski, Paweł; Pyrzak, Paweł
Effective exploitation of matured oil fields became important problem because of high oil demand. It is possible to increase recovery factor by application adequate secondary or EOR method of exploitation. In this work efficiency analysis of water flooding and polymer flooding for Carpathian oil field was done. Results of multivariant numerical simulations shows, that for selected heterogeneous reservoir polymer flooding is much efficient and could be used directly after primary recovery.
Analiza zmian koncentracji na światowym rynku gazu ziemnego
(2010) Kryzia, Dominik
This article presents changes in degree of concentration that have occurred over the years on market of natural gas. Aspects such as resources, production, consumption, export and import of natural gas were taken into account. The level of concentration was calculated on basis of participation of individual countries in terms of global data values. The calculation of concentration degree was made also for the world as a whole on the basis of the shares of the different regions. Importance of degree of market concentration on formation of level of energy security was also explained. To measure concentration Herfindahl-Hirschman Index (HHI) was used. The rest of article examines changes in calculated value of HHI and discuss the most important of them. Assesses their significance and determined effects of which have on the natural gas market. The article also attempted to determine direction of future changes to degree of concentration.
Czynniki kształtujące ceny ropy naftowej na świecie w 2009 roku
(2010) Kaliski, Maciej; Jedynak, Zdzisław
The purpose of article is to identify the phenomena which take place in the socio-economic environment in the world. The actions taken will make it possible to determine their influence on the level and dynamics of petroleum price changes in 2009. It presents available predictions in 2010-2011.
