a continuous stream into the pipe , this question is answered by the specialists of the tyumen oil research centerhe era of light oil is behind the extraction of black gold. today requires the use of new approaches from modern technologies. extraction methods depend on the depth of the composition of the mountain gates and many other factors, they can only be studied in the laboratory. for this, special samples of rocks are taken at the deposits. they are called kern - this is a rock sample that is mined in the field when drilling wells. by studying it , we can get information about oil and gas deposits, even if they are very deep underground, for example, this sample, sampled at a depth of 1700 m, but today there are no direct methods for studying the properties of the rock. we can only do this in a laboratory facility in our research center with about 400 units high. similar modern equipment is operated by highly qualified specialists and experts . in our center, core is stored from almost all of russia. from the volga to sakhalin , one of the most important characteristics of rocks is permeabil
