The practice of carbonate reservoirs fissure voidage determination at the calculation of oil reserves at the Bashneft ANK OAO fields
Authors: A.V. Shuvalov (Bashneft ANK OAO), F.A. Zainullina (Bashneft-Geoproekt OOO)
Special work for fissure voidage determination with the methods of wave acoustic logging as well as studies of large format sections are carried out. Fracturing parameters of rocks of Novo-Uzybashevskoye, Malyshevskoye and Tsvetaevskoye fields are given. It is established, that the cracks in the structurally complex carbonate reservoirs are not only the filtration channels, but also the container for oil.
