| الوصف: | Seismic modelling has been applied to define the porous carbonate intervals and lithologic boundaries resolved in the seismic section at the Løgumkloster‐ 1 Well, southern Jylland, Denmark, This well encountered a 14‐m thick, porous Zechstein carbonate interval (Ca‐2) with an oil show, but the well was plugged and abandoned. Band‐pass filtering and blocking of the acoustic‐impedance log in the time domain have been used to define a number of successive acoustic‐impedance models. The simplest of these, from which a synthetic seismogram correlates with the synthetic seismogram derived from the original acoustic‐impedance log, is assumed to define the maximum number of intervals resolved in the seismic section at the well location. As the well data was acquired in an area represented by a variable seismic reflection pattern, a new optimal seismic section CMP location was found, to optimise the correlation between the synthetic seismogram and the seismic section. Fifteen acoustic‐impedance intervals could be resolved in the seismic section at the Løgumkloster‐1 Well location, including the porous Ca‐2 carbonate interval. A close relationship was found between the Ca‐lb, Ca‐2 and Ca‐3 carbonate layers and lateral variations in the seismic reflection pattern, which indicates significant porosity variations. |
