A well is plugged by setting mechanical or cement plugs in the wellbore at specific intervals to prevent fluid flow. The plugging process usually requires a workover rig and cement pumped into the wellbore. The plugging process can take two days to a week, depending on the number of plugs to be set in the well.

Requirements for plug and abandonment of an oil/gas well - Legislation and Job design Materials to be used Abandonment techniques (placement methods, etc. including some of the new technologies that are out there already). The resin plug was then pressure tested and milled allowing the well to be circulated with full returns and a new 4-1/2” liner cemented in place. The job was a success proving resins can be used for P&A and, also, it can be placed safely with one of the smaller available coiled tubing pipes in the market. Well plug & abandonment (P&A) The basic of P&A operations vary little, whether the well is on land or offshore, and the oil and gas industry has developed methods and materials designed to provide long term zonal isolation even when downhole change over the time. Initial well-plugging steps include accurate measurement of the well dimensions and removal of all obstructions. Step 3. Disinfect the well by adding household bleach. All wells containing standing water must be disinfected to kill existing microorganisms. An oil or gas well is plugged and abandoned when it reaches the end of its useful life or becomes a dry hole. These operations include activities and tasks that present hazards to workers. The following sections discuss some of the hazards that could most likely be encountered during well plug and abandon operations and present possible solutions to these hazards. Although most oil and gas wells that are no longer productive are plugged by the responsible operators, the Railroad Commission of Texas administers a program to plug abandoned oil and gas wells.
