On the Issue of Isolated Well Productivity in a Number of Areas of the Republic of Sakha (Yakutia)

Abstract

A brief analytical review of isolated industrial inflows of oil and gas in a number of areas of the Republic of Sakha (Yakutia): Buyaginsky, Kederginsky, Russkorechensky and South Tigyansky. The recorded industrial inflows were suggested to be confined to zones of “flower-type“discontinuous violations. In all the considered areas, promising structures are or were located in zones of subhorizontal tectonic compression and shear stress. As an example, the features of the oil and gas potential of the Yuzhno-Tigyansk heavy oil field are considered in more detail. The model of the “flower type” structure and its isolated industrial oil flow in the South-Tigyansky area. Based on the proposed model of oil and gas potential of the areas, the conclusion is made about the direction of geological exploration in the “flower” structures to the lower potentially feeding areas of the subsurface.
