Safety and health hazards during servicing wells: the example of slickline services
(AGH University of Science and Technology Press, 2021) Mazur, Chrystian
In the oil and gas industry there are many serious hazards. Possible aftereffects of accidents happening on wells producing gas or crude oil can have fatal consequences. Natural dangers such as high pressures, flammable and explosive fluids, $H_{2}S$ content all make every project demanding and special care should be taken when planning works in harsh conditions. There are many precautions that could be done to ensure the long service life of the production wells and these can be achieved with slickline services. Slickline is usually a good first choice to conduct operations on live wells, and the potential risks during this work should be analysed since safety measures are crucial for both people and the environment. Only after assessing them correctly can work be done securely and in a timely manner.

Total Specific Energy (TSE) as a new indicator of drilling efficiency
(Wydawnictwa AGH, 2017) Toczek, Przemysław; Wiśniowski, Rafał; Stryczek, Stanisław; Ziaja, Jan; Mazur, Chrystian
Knowing the data from drilling works which had been carried out in a given area gives the opportunity to develop the next borehole with great precision. An important element of the design is to analyze and interpret data in detail, which can be used during the following drilling process. Based on a literature analysis, certain methods of the selection of drill bits have been indicated. Mechanic specific energy curves of drill bits applied in drilling works in northern Poland have been compared. The drilling works took place in the Precambrian platform. The compared mechanic specific energy curves were calculated with the use of R. Teale and H. Rabia equations. A relation between mechanical specific energy and pressure loss in polycrystalline diamond compact drill bits was determined. New drilling ratio TSE - Total Specific Energy which considers hydraulic power energy in the nozzles of the drill bit was calculated.
