As an example, the state Most workovers require the production tubing string to be pulled from the well by are required in the vast majority of the onshore oil producing wells in Russia. Frequently, cementing operations are carried out on existing wells to shut off Online Workover/Completions Well Control course at the Supervisory Level. most dangerous gases experienced during oil and gas operations, exploring the 30 Sep 2019 Katch Kan can help thanks to our zero-spill installation system, which ensures your workover operations will proceed safely and efficiently. Because of short space among the producing wells, workover operations become challenging and require developing new Simultaneous Operations
[Well Workover and Intervention] The process of performing major maintenance or remedial treatments on an oil or gas well. In many cases, workover implies the removal and replacement of the production tubing string after the well has been killed and a workover rig has been placed on location. Workover activities include one or more of a variety of remedial operations on a producing well to try to increase production. Hazards related to workover activities may include: Sand Cleanout; Repairing Liners and Casing; Well Recompletions Sidetracking; Plug-Back Workover operations mean the work conducted on wells after the initial well-completion operation for the purpose of maintaining or restoring the productivity of a well. Well completion/well workover means those operations following the drilling of a well that are intended to establish or restore production.

Before a workover can begin, the well usually has to be killed. This means that the pressure of the formation has to be equaled by pressure from above, usually by injecting treated water, oil, or formation water into the well. This brings the flow of formation fluid to a temporary halt. [Well Workover and Intervention] The process of performing major maintenance or remedial treatments on an oil or gas well.

This discipline covers various technologies that range in complexity from running basic slickline-conveyed rate or pressure control equipment to replacing completion equipment. COMPLETION WORKOVER PLANNING DRILLING DEPARTMENT WORKOVER PLANNING The term workover is used to refer to any kind of oil well intervention involving invasive techniques, such as wireline, coiled tubing or snubbing. More specifically, a workover refers to the expensive process of pulling and replacing completion or production hardware in order to extend the life of the well. Workovers are normally required to temporarily abandon or to plug and abandon a well. Operations may include squeeze cementing, setting plugs (cement or mechanical), retrieving production equipment, and perhaps cutting and pulling casing. Workover costs vary depending on well conditions and regulatory requirements.
