​​Cup Packer​

A cup packer is a downhole tool that uses elastic cups (typically made of rubber or polyurethane) to create a seal within casing or wellbore walls. It is used for zonal isolation, fluid control, or well testing. Simple in design, it is suitable for temporary sealing operations. Cup packers are primarily used in the following scenarios: 1.​​Oil and Gas Well Testing​​: Temporarily isolate zones for pressure testing or fluid sampling. 2.​​Drilling Operations​​: Seal off different formations during drilling to prevent fluid cross-flow. 3.Workover and Completion​​: Used for well cleaning, cement squeezing, or temporary zone isolation. 4.​​Water Injection and Acidizing​​: Isolate target zones for directed injection or acid treatment. 5.​​Shallow to Medium-Depth Wells​​: Suitable for temporary operations in shallow or medium-depth wells due to limited pressure resistance.
