Abstract: Uneven production along the long horizontal section could result in premature water or gas break-
through. Inflow control devices (ICD) )are usually applied between the isolation packers to adjust the production
profile of isolated well section. The ICD unable to be adjusted according to the reservoir production. To address the
issue, a multinode all-electric intelligent completion system has been developed. A unique feature of the system is
that the active flow control device is applied to divide the long horizontal wellbore into multiple production units and
a single TEC cable is used to remotely control the inflow of each production unit separately. The traditional inflow
control device completion technologies and the Multinode all-electric intelligent completion system components
and advantages have been introduced. Taking a horizontal well with completion string installed with traditional ICD
as case study the multinode intelligent completion design has been studied. The potential advantages and its first
field application have been introduced. Final recommendations are proposed to promote research and development of
AFCD ownhole valve, inflow control tools with functions similar to Multinode all-electric intelligent completion
system and intelligent completion technology, in order to provide solid technical reserves for hidden and marginal
reservoir development
