geusb-4823	Japsen, Peter; Bruun, Anders; Fabricius, Ida L; Mavko, Gary	Identification of hydrocarbons in chalk reservoirs from surface seismic data: South Arne field, North Sea	2005	4	.pdf	application/pdf	2871	144	63	Sw V el o ci ty Comparison of well log data and seismic data Two approaches may be followed to estimate the acoustic properties of the virgin zone in order to compare well data with seismic data (both are based on Gassmann’s equations): 1. The AVO attributes were calculated from the angle-dependent impedance inver- sions combined with information on the absolute level of chalk velocity which is not contained in the seismic data (Bach et al. 2003).	cache/geusb-4823.pdf	txt/geusb-4823.txt
