Abstract

Prikazane su teorijske osnove proračuna zavodnjavanja te proračun zavodnjavanja Craig-Geffen-Morseovom
metodom (CGM). Također je dat cjelovit primjer proračuna s konačnim rezultatima. Proračun je olakšan
upotrebom tabličnog kalkulatora i prilagođenih funkcija (user defined functions, UDF) unutar Visual Basic for
Applications (VBA) interpreterskog jezika inkorporiranog u Microsoft Excel. Izrađen je niz funkcija za interpoliranje
između poznatih vrijednosti poput relativne propusnosti za vodu i naftu, parametra C, te niz funkcija za
korelaciju dijagrama koji su prvobitno izrađeni iz empirijskih podataka. Pokazano je da potpuno analitičko
rješavanje proračuna zavodnjavanja može davati dobre, ako ne i bolje rezultate nego originalno rješenje grafoanalitičkim
načinom.

Abstract (english)

Abstract: In this work, theoretical basis for waterflood calculations, and also for Craig-Geffen-Morse (CGM) waterflood
calculation was given. Likewise, the example for the entire calculation method was shown. The calculation was
faciliated by use of spreadsheets and user defined functions (UDF) that are available to create as a part of Visual
Basic for Applications (VBA) module in Microsoft Excel. The number of functions was coded in order to
interpolate known values such as relative water and oil permeabilities and coefficient C, that were previously
obtained from diagrams based on empirical data. It was presented that completely analytical solution of the
CGM waterflood calculation can give acceptable if not even better results than combined graphical and
analytical solution.
