PROCESS OF SEARCH AND PROSPECTING FOR MULTIPOOL DEPOSITS OF OIL Russian patent published in 2000 - IPC

FIELD: prospecting for multipool oil and gas deposits in structures characterized by displacement of vaults over different stratigraphic levels. SUBSTANCE: search well is sunk on basis of seismographic data and drilled to basic horizon. On basis of statistical analysis of geological and geophysical materials with reference to outlines and vaults of lower and upper prospecting floors and of tectonic structure of territory search of lower floor is conducted by sinking prospecting well which is drilled to the rise of layers in profile with search well at distance of 0.7-1.5 km from it. EFFECT: growth of success factor in search and prospecting drilling for exposure of oil fields in Devonian deposits, reduced material expenditures for these activities. 1 cl, 1 dwg
