Geophysical methods control and definition of the oil-water contact

Process of development of gas and oil fields includes a complex of geophysical surveys in the operating wells placed within the operated deposit. At design and control of development of oil and gas fields the geophysical methods of research solve various problems, one of which is definition and control over the provision of the gas-liquid contact and oil-water contact level. In this article the GIS main methods for definition of initial situation and observation of movement of gas-liquid contact and oil-water contact are briefly considered.
