Abstract

In the article analysis of research works focused on terms and reasons of the annular pressure buildup is presented. Three types of processes having influence on the annular pressure buildup are discussed. Increments of temperature with time in annulars are calculated using TERMOSIMTM software application. Values of annular pressure buildup were defined using the semisteady-state approach of thermodynamical processes. Annular pressure buildup curves in shut-in phase were estimated with the use of annular pressure data in flowing phase. The relationship between changes of annular pressure and pressure build-up rate was estimated

Key words:

annular pressure, annular, process of thermal expansion, spectral noise logging, annular pressure buildup curve, semisteady-state approach of thermodynamical processes, change of annular pressure, coefficient of isobaric thermal expansion, coefficient of isothermal compressibility, TERMOSIMTM
