Selection of lower completion equipment is a major factor defining the well production life and whether the well will be capable of maintaining high performance throughout the whole production life. This paper presents a review of key elements that the lower completion assembly consists of, such as: wire-wrapped filter, open-hole packers and inflow control devices. The authors believe that these devices are integral parts of a horizontal well. Wire-wrapped filters and inflow control devices are used to smooth out fluid-movement profile and control sand production. Including open-hole packers into a lower completion assembly is required if the reservoir has heterogeneity in horizontal section. Packers are divided into groups depending on how they are set: there are swelling packers, hydraulic or mechanical-hydraulic packers.
