Study of Changes of Reservoir Temperatures in Plan and Section of YaNAO

The study is about main features of reservoir temperatures at oil and gas fields of the Yamal-Nenets Autonomous District. The study is based on the results of measurments of reservoir temperatures in prospecting and exploration wells. The authors have created zoning scheme of the Yamalo-Nenets Autonomous District and derived a set of equations to predict the value of the initial reservoir temperatures. The results of the survey should help to improve the efficiency of exploration drilling, as well as improve the quality of assessment of gas resources in perspective areas of YaNAO.
