Decision-making problem with assessing of the suitability of geological structures located in aquifers in terms of their use for carbon storage, natural gas storage or waste injection is mainly connected with the necessity of taking into consideration a large number of criteria and analyze a lot of parameters. It also connected with making many independent decisions concerning geological, environmental, social, political, technical or legal issues. This article shows the possibility of using the AHP method, ie. multi-criteria hierarchical methods to analysis of decision problems in assessment the potential of aquifers. AHP method allows to take reasonable decision. The article was divided into three parts. The first one includes a characteristics of geological structures located in aquifers, special attention was paid to the criteria describing these structures. In the second part, the basis for decision-making system based on the method of AHP, which was used to carry out the hierarchical scoping assessment of potential structures. Validation of decision-making system was realized on selected geological structures located on the Polish Lowlands. An assessment of the possibilities to use the two anticline in the Mesozoic aquifers was made. As a result, received the criteria ranking, rankings of decision variants to all criteria and global ranking of variants. Based on the results obtained can be determine which decision represents a priority way of use structure.

W artykule zaprezentowano badania nad doborem odpowiedniego zabezpieczenia antykorozyjnego instalacji i uzbrojenia wgłębnego czterech odwiertów, z dwóch różnych kopalni, przeznaczonych do zatłaczania odpadów i wody złożowej. Działania mające na celu zapewnienie ochrony przed korozją wyposażenia ww. odwiertów obejmowały dwa etapy. W pierwszym określono warunki pracy instalacji oraz ustalono sposób prowadzenia testów. Powyższe zadania stanowiły wstępny zakres prac niezbędnych do zaplanowania dalszych działań, w szczególności właściwych testów korozyjnych mających na celu dobór skutecznego zabezpieczenia antykorozyjnego, które wykonano w drugim etapie prac. Artykuł prezentuje sposób realizacji poszczególnych zadań oraz uzyskane wyniki.

In this article laboratory study is presented which was performed to select proper anticorrosive protection of installation and underground equipment in four wellbores, from two different fields, destined for injection drilling wastes and deposit water. Operations aimed at protection of the equipment included two stages. The first included determination of work installation conditions and the test conditions. These tasks represent the initial scope of work necessary to plan further actions, in particular the proper corrosion tests to select an effective anticorrosive protection which were performed in the second stage. The way of realization of particular tasks with obtained results were presented in this article.
