Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 22–25, 2021
Paper Number: SPE-204404-MS
... Abstract Squeezing perforated intervals is very common in oil and gas wells, either for isolation to produce from another zone or during P&A applications. Though cement is the common material used in this application, sometimes cement is not ideal. A few of these instances are: 1. The...

...-pressurization, mechanical/chemical degradation, and/or a poor cement job, thus reducing the sealing capacity of the site. Wells that leak due to microannuli or cement fractures on the order of microns are difficult to seal with typical workover techniques. We tested a novel polymer gelant, originally developed...

... Abstract A cement barrier in an oil well is intended to prevent any movement of fluid along the wellbore. If there is movement of fluid, acoustic energy will be produced and may be detected by a suitably sensitive sensor. This paper describes the controlled testing and real world application of...
