    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:
    Coal mine methane from post extraction coal gobs is most efficiently produced with drilling wells realized from the surface. In Polish conditions, such wells are most frequently drilled in highly urbanized areas and residential quarters. The drilling of such wells creates the hazard of exceeding admissible noise levels in the areas requiring acoustic protection during the day and night. Therefore it is very important to assess the level of noise emitted by the rig and to establish the isophones 45 dB and 55 dB for various field conditions. With such information, the location of the rig can be properly selected at the stage of well design. The level of noise emitted in the environment during the drilling of experimental gas well Wieczorek-AGH-1, was established on the basis of noise analyses performed within the well pad area and its closest vicinity with the reference method, described in the Regulation of the Environment Minister of 30 October 2014 concerning the requirements of the analyses of emissions and the quantity of water consumption (Official Journal of 2014, item 1542), hereinafter called the Regulation.

    Opis:
    In Poland the perspective shale gas formations concentrate in the area of the Baltic Basin, Podlasie Depression and Lublin Basin. Their depth varies from slightly above 2,000 to 4,500 m, depending on the location. Accordingly, novel rigs of high hoisting capacity and installed power capacity of master motors have to be used for opening natural gas deposits with the use of directional wells. The operation of such systems creates an acoustic hazard for the environment, especially in the close vicinity to the rig. The results of noise analyses of a prospecting well for hydrocarbons from unconventional sources in the north of Poland performed with the use of a rig MASS 6000E are presentedin this paper. The noise analyses concentrated on the rig area among the direct noise sources and the neighborhood to show the influence of drilling operations on the acoustic environment. The obtained results revealed that the noise emission in the rig area can be limited by optimizing the localization and placement of particular objects and systems within the rig site. This also applies to the placement of the noise barriers on the border of the rig to limit the noise emission towards objects requiring protection.
