Effectiveness of the use of BGPh-method
In addition to the above examples, there are still a significant number of studies that confirm the high efficiency of the BGPh-method in the search for oil deposits, these works are included in Table.
Table includes 97 investigated structures at 37 sites. Based on the results of wells testing, including previously drilled wells, the success rate of 141 wells is 94%. In addition, on the territory of the Samara, Orenburg, Ulyanovsk, Perm, Chelyabinsk and Kurgan Regions and in the Republics of Tatarstan, Bashkortostan, an additional study was conducted on 14 licensed sites, the results of which, for reasons of confidentiality of information, are not included in Table
