Monitoring and elimination of intercasing pressure

Abstract

Background: The appearance of intercasing pressure in many cases is associated with inadequate quality of primary cementing. Despite the fact that many studies are aimed at preventing problems of primary cementing, at improving the quality of well completion, it should be noted that the problem of intercasing pressure at existing gas and gas condensate wells is increasing.
 Aim: The purpose of this work is to study and eliminate wells with intercasing pressure at the Amangeldy gas condensate field.
 Materials and methods: This paper presents the procedure for preparing the well and carrying out the elimination of intercasing pressure, as well as the chemical components of cementing slurry.
 Results: The conducted studies and measures on wells No.121; No.105; No.103 and No.101 showed a positive result and the effectiveness of the composition of cementing slurry.
 Conclusion: The presented technology for the elimination of intercasing pressure and the composition of the cementing slurry can be widely used in many fields of Kazakhstan.
