What is upper completions?

Upper completions, also known as upper completion systems, are components of well construction used to create a seal at the topmost point of the wellbore. They consist of a variety of parts including tubing hangers, packers, valves, and seals, which work together to ensure that the well is properly sealed.

Upper completions are important because they help to prevent unwanted fluids from entering or leaving the wellbore. This helps ensure that the well operates efficiently and safely. Upper completion systems are also critical for the extraction of oil and gas from the reservoir, as they allow for the placement of pumps and other equipment necessary for production.

There are several types of upper completion systems available, each designed for specific well conditions and production needs. Some of the most common types include subsea completions, platform completions, and floating production systems.

Overall, upper completions are a crucial component of the well construction process and play a critical role in ensuring that oil and gas can be extracted safely and efficiently from deep underground reservoirs.
