| O&G | gas check cement | цемент с повышенными газоизоляционными характеристиками (GAS-CHEK cement additive was introduced to provide an effective means of helping prevent gas flow into the annulus after cement has been placed. Historically, the industry has been plagued with the problem of annular gas flow following completion of cementing jobs. Numerous corrective practices have been attempted in order to help prevent annular gas flow, but previously no completely reliable process had been found. Kenny Gray) |
