Abstract
Thawing of frozen ground, surface subsidence and formation of funnels in wellhead area during operation can lead to stability disturbance of wellbore and its lateral displacement. Effective solution of this problem which helps to minimize thawing area around well is use of insulated tubing (thermocase). The article presents the results of forecast modeling of soil bases temperature regime. The minimal length of thermocase depending on well spacing and criteria for its determination were set for multiple well pads of Vostochno-Messoyakhskoe field.
