The calculations of thermal field parameters at oil and gas fields for the Chernihivskyi and Lokhvitskyi blocks of DDB allowed us to define geothermal gradient changes with depth. At all fields, there are wells with stable gradients of 19—21 °C/km, and ones with sharp changes. On the Chernihivskyi b...
