Abstract

U ovom diplomskom radu napravljena je interpretacija seizmičkih horizonata na plinskom polju Katarina u računalnom programu Petrel 2014. Plinsko polje Katarina smješteno je u podmorju središnjeg dijela Jadrana, u istraživačkom bloku Aiza–Laura zajedno s eksploatacijskim poljem Marica. Svrha ovog rada bila je interpretacija krovine ležišta na ovom polju kako bi se dobile vremenske i dubinske karte koje mogu biti korištene u strukturno–tektonskoj interpretaciji samih ležišta. Interpretirane su četiri krovine ležišta: PLQ1–A, PLQ1–D, PLQ1–D1 i PLQ–A. Također je interpretirana krovina formacije Santerno te pretpliocenska diskordancija. Izrađeni su sintetski seizmogrami za bušotine Katarina–1 i Katarina–2 koji su služili povezivanju podataka o dubinama ležišta i podacima sa seizmičkih profila u vremenskom mjerilu. Na temelju mjerenih seizmičkih podataka izračunati su i seizmički atributi koji su pomogli u interpretaciji: trenutna faza, kosinus trenutne faze, trenutna amplituda, trenutna frekvencija i atributi kontinuiteta.

Abstract (english)

In this graduate thesis, the interpretation of seismic horizons on the gas field of Katarina was compiled in computer software Petrel 2014. The gas field of Katarina is located in the subsoil of the central part of the Adriatic sea, in the research block Aiza–Laura together with the exploatation field Marica. The purpose of this paper was to interpret the enclosure in this field in order to obtain time and depth maps that can be used in the structural–tectonic interpretation of the bases. Four enclosures of PLQ1–A, PLQ1–D, PLQ1–D1 and PLQ–A were interpreted. The top of the Santerno formation and the prepliocene discordance were also interpreted. Synthetic seismograms for Katarina–1 and Katarina–2 boreholes were used, which used to link data on depth and data from seismic profiles at time scale. Based on the measured seismic data, the seismic attributes that have helped in the interpretation are calculated: instantaneous phase, instantaneous phase cosine, instantaneous amplitude, instantaneous frequency and the attributes of the continuity.
