Opis:
The paper presents some experimental test results of the influence of selected parameters (samples shapes, short and long creep and relaxation stages, environmental degenerative processes) on the mechanical properties and behaviour of the geosynthetic materials. The individual impact of the change of the above particular parameters on the materials are investigated and some practical conclusions formulated.

technology and results of drill stem test DST
Opis:
Gas-, oil- and water-bearing Upper Jurassic formations (Malm) in the area of the Carpathian Foothills are built from carbonate reservoir rocks with vuggy-fracture porosity system (or fracture-vuggy), which absolute porosity is from a few to several percent. At the end of the twentieth century DST tests provided a lot of reliable reservoir information, on which the important decisions for geological research and exploration, can be taken. The credibility of these tests results depends largely on the technology used. The paper presents the results of three selected DST tests, differing in technology, particularly with attention to the usefulness of the obtained information in explorations for hydrocarbon deposits process.

Opis:
The quality of the tests results is of paramount importance in the process of assessing conformity, conducted among the others, on the safety of the products use, their functionality or type approval. Ensuring the reliability of the results and their consistency should be an absolute priority in the operation of all appointed for this purpose metrology institutions and organizations, especially those units whose product offered to the customer are goods and services are based on measurements and their results. The essential criterion for assessing the quality of the results is their reliability to the user. One of the major issues that have a significant impact on the reliability of tests results is a form of reporting the results to the client. This paper addresses the key issues related to the presentation of the tests results. Discussed are the risks associated with the presentation of test results. The qualities that the measurement result should have to be reliable to the customer, have been identified. The significance of the accreditation for the validity of the results has been presented. Normative documents containing the requirements for the presentation of research results have been recalled. The information to be contained in a report from an accredited testing laboratory provided to a customer has been specified. The principles of the identification of the document describing the test methods have been discussed. Attention was drawn to the need for placing, in the report, the information about the uncertainty of the measurements. The principles of placing in the test report and the assessment of conformity as well as the opinions and interpretations, have been discussed. The detailed requirements for use, by research laboratories, the accreditation symbols in test reports have been presented

Opis:
The application of robust statistical methods to assess the precision (uncertainty) of the results of interlaboratory comparison tests is presented. The case, when these results may include outliers is considered. An usual rejection of such data reduces the reliability of evaluation, especially for small samples. The robust methods take into consideration all samples data including outliers. The use of the robust method Algorithm S is provided for estimating the precision of some measuring method tested in comparative studies in the group of accredited laboratories. Result obtained for simulated example is very close to the case with rejection outliers, but more reliable.

results of double-cycle drill stem test DST
Opis:
The paper presents the results of 25 industrial double-cycle drill stem test DST of the Malm carbonate rocks of the Carpathian Foredeep. Designated prospective levels were tested by DST to assess their productivity. DST tests were performed mostly in open hole sections of boreholes and rarely in cased hole - after earlier borehole casing perforations. Probes used American Standard company Halliburton and Baker Inflatable type. During testing of Malm reservoir rocks in approximately 75% was used double-cycle drill stem test DST. Due to renewed interest of the Polish Oil and Gas Company in petroleum prospection of Malm sediments, it is appropriate to use in the petroleum exploration results obtained thus far from industrial research double cycle DST reservoir testing. This provides, among others to modification of drilling technology and to sampling of Malm sediments in the planned boreholes.
