  Article abstract

Comparing core analyses and well logs using a Hungarian gas field as example
K. Sári
Preliminary communication

The purpose of this study was to build small-scale genetic models of a reservoir by comparing the small and medium scale information derived from core analyses and well logs. The examined gas field is situated in the eastern part of the Pannonian Basin System. For the numerical solution several one (univariate) and multivariable (multivariate) statistical methods were used to describeone and multidimensional similarities. Finally a multivariable identifying model summarizes the information gained in different scales. The analyses showed that there was a correlation between the rock physical properties and the shapes of well logs. The porosity and the permeability did not depend on the individual log shapes but the most typical log shapes of the rock body which resulted from the electro-facies. The oscillation of the pore throat size distribution caused small changes on the log. This model can be regarded as a tool for classifying new information according to the genetic hierarchy identified.

 

 

Korelacija litostratigrafskih jedinica u Dravskoj depresiji (hrvatski i mađarski dio)
K. Sári
Prethodno priopćenje

 

Svrha ove studije bila je izradba genetskih modela ležišta "sitnijega" mjerila usporedbom informacija na manjoj i srednjoj skali, a dobivenih analizama jezgara i dijagrama karotaže. Ispitano plinsko polje nalazi se u istočnom dijelu Panonskoga bazenskoga sustava. Za numeričko rješenje korištene su statističke metode s jednom i više varijabli (univarijantne i multivarijantne) kako bi se opisale jedno- i višedimenzionalne sličnosti. Na kraju, multivarijantni identifikacijski model sažeo je informacije dobivene u različitim mjerilima. Uočena je korelacija između fizičkih svojstava stijene i oblika karotažnih dijagrama. Šupljikavost i propusnost ne ovise o obliku pojedinačnih karotažnih dijagrama već o najkarakterističnijim oblicima karotažnih dijagrama stijene koja je promatrana kroz odnosne elektro-facijese. Također, oscilacije dimenzija "ulaza šupljina" (tj. prostora na dodiru dvaju zrna, a koja povezuju veće susjedne šupljine) uzrokuju male promjene na karotažnom dijagramu. Predstavljeni model može se smatrati alatom za klasifikaciju novih informacija u skladu s utvrđenom "genetičkom" hijerarhijom (stijena).

Over the years we have reported several times on crimes and violence related to sneaker releases and the sneaker scene in general. Where there is money to be made, you can be pretty sure that sooner or later there will be people that want to take it from you. Focus Films presents Kicks, a film about sneaker violence and much more.NIKE AIR FORCE 1 FLYKNIT “When his hard-earned kicks get snatched by a local hood,NIKE AIR MAX 2017 fifteen-year old Brandon and his two best friends go on an ill-advised mission across the Bay Area to retrieve the stolen sneakers. Featuring a soundtrack packed with hip-hop classics, Justin Tipping’NIKE AIR HUARACHEs debut feature is an urban coming-of-age tale told with grit, humor – and surprising lyricism.”NIKE AIR FORCE 1 HIGH CHEAP The story is based on an experience that Justin Tipping,ADIDAS ALPHABOUNCE the director of the film, had. He purchased a white Nike Air Presto and was jumped by several guys and got his sneakers stolen. Of course his film is much more than a boy-meets-shoe, boy-loses-shoe,MBT KIMONDO MEN boy-gets-shoe-backstory. Brandon,MBT Flame Chaussures the main character in the film, gets his brand new Air Jordan 1 Retro “Bred” stolen and the film tells the story of him and his friend’s tale trying to get them back.NIKE AIR JORDAN RETRO 5 The result is a quintessential urban American tale, a subject that is relevant and real for today’MBT KIMONDO GTX MENs American youth. Here below you can watch another clip of the upcoming movie.NIKE AIR HUARACHE CHAUSSURES Kicks hits theatres September 9. Source: The Guardian .
