becomes PGNiG at the beginning of of August 2008 a 280km long „2-D “seismology program in the southern part of the concession blocks of the JOA begin. A goal of the Seismology of program is it, the accurate drill location for two deep Explorationsbohrungen too determine. Seismology - treasure search with most modern technology In the process of geologic history oil and natural gas walked from the source rocks direction earth's surface. Blocked impermeable rock formations, e.g. Clay/tone, the way and so-called traps formed, collected themselves for oil or gas under the highest point and formed ideally today's stores. Due to different education conditions deposits of natural gas are usually found in larger depths than Erdöllagerstätten, whereby because of the different density oil gas over the oil and water is to be always found underneath the hydrocarbons. Stores rocks are porous and permeable; Oil and gas settle in the tiny, otherwise water-filled pores. Stores on the trace In order to come stores on the trace, today large areas first with highly soluble Satellitenaufnahmen are seized and from airplanes regarding variations of the heavy and of the magnetic field examined. The by far most important technology apart from these methods of general surface geology is however the study of the underground by seismology. The principle of the seismology consists of producing at the earth's surface or close for the sea surface acoustic waves and catching their echo of the different rock formations of the underground. Depending upon density and condition of the rock reflections fail differently. Porous rock - and only in this gas and oil can occur - absorbs acoustic waves, hard rock reflects it. 2D-Seismik By 2-D-Seismik one wins only a two-dimensional vertical sectional view of the earth layers below a line. With the modern 3-D-Seismik against it several lines are netlike arranged by acoustic sources and receivers. With this procedure a three-dimensional picture of the underground is won below the presumptuous surface. The production of the oscillations for seismic investigations on the country takes place via igniting small explosive loads in boreholes or via special vehicles, at which heavy vibrating plates are attached. Touched down on the ground these plates produce vibrations, which penetrate the underground several thousand meters deeply. Planarly laid out geophones, small earthquake measuring stations comparably, seize these reflected acoustic waves at the earth's surface. A geophone exists in the core of a spiral held by feathers/springs in a magnetic field. It converts the acoustic waves into electrical impulses, which are then noted in a central measuring station digitally.
