The following provides information based on past experience of the retrievability of packers, which provides general trends and guidelines for the execution of such activities. However, every well is different and as such hard and fast rules are not possible to giive.

The article identifies the most common factors which can play a role in premature failures of packer seals: 1. Installation procedures Storage damage: ageing (heat, sunlight or radiation); distortion (poor support, heavy loads). Friction damage: non-uniform rolling or twisting, or abrasion by un-lubricated sliding. Cutting by sharp edges: Inadequate taper on corners, sharp edges on … Causes of Packer seal failure

Perforation prepacking refers to the methods that can be used to pack the perforation tunnels with gravel prior to filling the screen/casing annulus. The main objective of prepacking is to maximise the quantity of high permeability gravel placed in the perforation tunnels (or in cavities behind the casing) which is one of the key factors … Completion Operations – Gravel Packing Procedures
