Saudi Aramco has installed over 64 hydraulic wet connect (HWC) tools to
combine smart well completions (SWCs) with electrical submersible pumps (ESPs)
over the last 6 years. These completions are installed for remote inflow
control in Maximum Reservoir Contact (MRC) and Multilateral (ML) wells in Saudi
Arabia fields. This paper describes case studies of HWC completion options,
design, and installations, including several successful replacements of ESP in
Intelligent completions were nearly started 15 years ago to provide
selective zonal/lateral control, delay water breakthrough, control water
production, shut-off wet zone/lateral, reduce operational expenditure (OPEX),
enhance safety by minimize intervention, optimize production and/or enhance
The HWC system provides two main advantages. 1) The first advantage is
to replace the ESP when required without the need of retrieving lower
intelligent completions system, which saves both workover-rig time and
ultimately cost. 2) The second advantage is to complete extended reach (ERD)
with shallow TVD to install completions in two stages: The first stage is to
install lower intelligent completion with receptacle and drill pipe to reach
TD. The second stage is to install upper completion with stinger and tubing as
per the design, and calculations of torque and drag to establish communications
with lower intelligent completion.
In several wells, upper completions have been successfully recompleted
with ESP. Therefore, the technology has proven its real value, especially in an
This paper will cover case histories, best practices, lessons learned
and new advancement in HWC and related technologies.
