What is well completion? Well, it is a series of procedures performed on a drilled and cased gas and oil well to prepare it for production. The process involves downhole tools like (downhole packers, safety valves, mandrels, pumps, etc) and running production tubing. In addition, well completion also involves stimulation and perforating the well, which is otherwise known as frac. In addition, well completion also includes acidizing and nitrogen circulation, whenever needed. Different types of equipment are required in the process of well-completion. Let’s take a plunge into what are these equipment and how they work.
Inflow Control Device The equipment used in well completions to distribute the inflow equally is known as an inflow-control device (ICD). The premise for various ICDs is the same, regardless of the differences in the specific structures between designs— they restrict flow by adding extra pressure drop and subsequently altering the wellbore pressure distribution. One can reduce water or gas coning, avoid sand formation, and address other drawdown-related production issues with a more evenly distributed flow profile. ICDs are often not movable; once inserted into the well, the device's position and the connection between rate and pressure drop are set. Because of this, well completion and ICDs' design are crucial to production. Depending on the condition of the reservoir, the overall build of the well, and the completion design, ICDs can either help or hurt output. The effect of an ICD is a function of time because it is known that reservoir conditions would change during a well's life. Uncertainty and reservoir heterogeneity can easily make things more challenging. If the design is solely based on reservoir flow simulations in beginning circumstances, the ICDs may occasionally be overlooked. Casing Accessories Casing valves are a type of valve used to access a well casing. They are also known as blowout preventers, casing control valves, etc. The casing can be thought of as the "straw" used to "suck" the product (whether it is liquid or gas) out of the earth. These casings are telescopic, which means they are made up of numerous tubes that fit inside one another to form a telescope-like structure as they get further and deeper into the earth. In cased hole completion, they guard against cave-ins and shield the well from undesirable geological formations. Casing valves are positioned directly above the point where the well casing begins and are a component of a wellhead assembly. Access is provided to the area between these telescoped tubes via the casing valve (otherwise called the annulus). To fortify the well, these annular areas are frequently filled with concrete. Depending on the design, casing valves can be used to pump in concrete or remove the extra material. They are an essential part of the oil and other drilling applications because they offer pressure release and other safety measures. Conclusion Just like casing accessories and inflow control machines, well completion might also include other processes that involve liner hangers, Sand Management Services, modular screen plants, and plunger lifts.
