..., because the average gas-production rate of a single well is greater than 700 000 m 3 /d, and the wellhead temperature is greater than 90°C during production, the wellhead generally is lifted. After the gas reservoir was put into operation, under the influence of the rise of wellbore temperature, 33...

... was promising and, within a few months, was ramped up to 70% of the targeted CSS field peak oil rates. Overview of CSS Performance A typical CSS cycle in an A East well is shown in Fig. 1, using the wellhead temperature sensor as an indicator. The cycle starts with the injection phase for several weeks...

... and the design of well completions require accurate simulation of thermal behavior in the wellbore and in the permafrost. Wellhead temperatures of producing wells also must be predicted so that surface facilities can be designed properly. Several studies describe thermal models for predicting permafrost thaw...
