Well Completion and Workover

BACKGROUND:

Well completion and workover represent two essential activities in the oil and gas industry, applicable to both oil and gas wells. The initial completion process enables production fluids to flow into the wellbore and subsequently to surface facilities. Conversely, workovers are necessary when production levels begin to decline over time. Thus, workovers are often performed repeatedly. Typically, well completion occurs only once in the life of an oil or gas well, whereas workovers may take place regularly whenever a Production Engineer identifies an opportunity to enhance production rates.

Engaging in oil and gas activities entails significant capital investment and inherent risks, as operations involve flammable fluids, high pressure, and elevated temperatures. Therefore, all personnel involved must possess the necessary knowledge and qualifications, along with sufficient experience. However, it is common for some individuals to lack the required prerequisites for their roles. As a result, supplementary training may be necessary to ensure that operations are conducted safely, technically sound, and environmentally friendly.
