EVALUATION OF GRAVITY ANOMALIES BY DIRECT INTERPRETATION TECHNIQUES: AN APPLICATION FROM HASANKALE-HORASAN REGION

In this study, by using Normalized Full Gradyant (NFG), Andreev-Griffin variation and statistical methods, gravity data were evaluated. The influences of hydrocarbon existence on theoretical anomalies were produced by performing analytical downward continuation of the NFG field. With performing Andreev-Griffin variation and statistical methods, the affect of existence of hydrocarbons on curvature of theoretical anomalies was observed. In the study area, Hasankale-Horasan, along the one profile measured gravity data were processed and interpreted by NFG, Andreev-Griffin variation and statistical methods. As a result of this study, by using NFG, Andreev-Griffin variation and statistical methods, potential hydrocarbon existence areas along the profile have been identified.

GRAVÝTE ANOMALÝLERÝNIN DOÐRUDAN YORUM YÖNTEMLERÝ ÝLE DEÐERLENDÝRÝLMESÝ : HASANKALE - HORASAN BÖLGESÝNDEN BÝR UYGULAMA

Bu çalýþmada, Normalize edilmiþ Tam Gradyan (NTG), Andreev-Griffin varyasyon ve istatistik yöntemler kullanýlarak, gravite verilerinin deðerlendirilmesine çalýþýlmýþtýr. NTG verilerinin aþaðý doðru analitik uzanýmý yapýlarak teorik anomaliler üzerinde hidrokarbon varlýðýnýn NTG kesitlerindeki etkileri ortaya konulmuþtur. Andreev-Griffin varyasyon ve istatistik yöntemlerden, teorik anomaliler üzerinde hidrokarbon varlýðýnýn eðri üzerine etkisi ortaya konulmuþtur. Ortaya konulan bu yöntemlerin bir uygulamasý olarak, Hasankale-Horasan petrol sahasý gravite verileri NTG yöntemi, Andreev-Griffin varyasyon ve istatistik yöntemler kullanýlarak hidrokarbon içeriði konusunda önemli sonuçlara varýlmýþtýr.
