Opis:: Hydraulic fracturing operations performed at the stage of gas prospection in shale formations are aimed at opening out gas residing in rock micropores. Large quantities of fracturing fluid, with physicochemical composition adjusted to their properties, are injected to the selected interval of a horizontal well. Finally, sand (proppant) is injected along with the fracturing fluid to support the newly formed fracture. The results of a computer simulation of noise emission generated by high pressure pumps during hydraulic fracturing operations, and the results of noise measurements during such work in the north of Poland are presented in the paper. The analysis of the obtained results revealed that the noise standards for day hours in the residential area localized ca. 320 m from the well pad was not exceeded for the hydraulic fracturing operations. The noise level in the night hours was considerably higher, therefore a respective sound berm should be construed.

Opis:: The potential change of natural gas composition in the near-wel lbore zone creates a big problem with the selection of appropriate initial value of counterpressure exerted by the displacement fluid on reservoir during the test, and also with the interpretation of the reservoir and production tests results. The analysis of the industrial data reveals that the effect of condensate production in the near-wellbore zone could take place while using too high counterpres-sure during DST tests, as a consequence of using a relatively high column of water displacement fluid in the DST column, i.e. about 2500 m. This thesis can be confirmed after further detailed theoretical analysis of the occurring thermodynamic conditions. The paper addresses technological and interpretation problems encountered during drill stem tests (DST) of gas-bearing Devonian strata, on the example of the Stryszawa field in the Western Carpathians. Special attention was paid to the possible changes of gas compo sition during flow tests and the cases of gas condensation of heavier fractions during build-up tests. Attempts were made at explaining sudden drops of pressure at the build-up stage along with the thermodynamic conditions responsible for this effect. The authors explained the necessity of using an appropriate Ful-Flo sampler in the DST set for collecting gas samples at any time of the test, and devices for continuous measurement of temperature. The use of new types of drill stem testers and appropriate interpretation methods, which would account for a detailed analysis of technological and reservoir conditions allows for more efficient oil prospecting and deciding about enhancement methods in hydrocarbon production. The analysis of thermodynamic conditions on the bottom of the wellbore allow s for selecting proper counterpressure values in view of the condensation of heavier gas fractions in the near wellbore rocks. The analysis of conditions in which heavier gas fractions undergo condensation is approximate and general because the gas samples were collected at the outlet of the DST string (in surface conditions), without a Ful-Flo sampler and without temperature measurements.
