Annotation:

The authors of the article consider the possibility of optimizing studies to control the development of an oil and gas condensate field located within the limits of Nurminsky oil and gas region of the Yamal oil and gas region. The field is complicated by faults identified by the results of 3D seismic surveys interpretation. It should be noted that some of them are low-amplitude or zero-amplitude ones. In many cases, the identified faults have the character of fluid seals that prevent free filtration of fluids, which leads to the localization of hydrocarbon deposits. A new approach to wells researching with the purpose of monitoring development and well selection criteria for reducing the number of studies is proposed; a model of the TP1-6 oil and gas condensate field formations is built, the filtration resistance indicators a and b are distributed as well as their distribution throughout the formation area, zones are identified that can be studied by a certain group of wells. Modeling is performed in the "Surfer" software package.
