Abstract


Well workover operations are often accompanied by unwanted events such as well kicks. A well kick is defined as an uncontrolled release of gas, oil or water to the surface through leaky threaded connections and damages resulting from loss of wellbore integrity during well operation.
PJSC TATNEFT operates production and injection wells drilled through multiple zones and equipped with single- and dual-string downhole assemblies. According to the Federal Rules and Regulations for Industrial Safety, a blowout preventer (BOP) shall be installed at the wellhead in such wells prior to workover operations to provide reliable wellhead sealing in case of a blowout during tripping long or short pipe strings.
There are several reservoir drive mechanisms that can cause well kicks, including water drive, elastic water drive, solution gas drive, gas drive, and gravity drive. All of them are associated with low to high risks of well kicks, with some reservoir drives requiring wellhead sealing (with BOP installation) when performing pipe tripping during well operation and workover.

Key words:

well kick, oil reservoir drive mechanisms, wellhead sealing, blowout preventer, well control hazards
