The purpose of this paper is to illustrate the possibility of testing full sized connections in sour environments. It is also intended to demonstrate to the industry that the pipe body is possibly more susceptible to cracking than is the premium connection fabricated from the same susceptible material.

In the framework of the injection of anthropogenic CO2 for supporting energy transition, more and more wells will be used for injecting dense CO2 streams. Dope free solutions for premium OCTG connections to replace both storage and running thread compounds are beneficial for saving time (lower running time), for environmental considerations (no discharge of dope) as well as improving running performances. However, they have never been qualified in dense CO2 stream environments containing brines, while dense CO2 is known to be a good solvent toward polymers. A test protocol has been designed for that purpose, that combines an exposure to dense CO2 stream then to CO2 saturated brine environment. The objective is to duplicate a CO2 injection well life, from the start of the production, shut-in phases with formation water going up the tubing and restart (saturation of the brines with high CO2 pressure). Evaluation of the performance of a proprietary dope free solution was done by direct comparison with conventional running compounds. It has been observed a resistance of the dope free connection to dense CO2 at least as good as the dope connection on a super duplex material.
