“…Producer wells are designed as openhole horizontal wells; the reservoir section, varying from 1,000 m to 2,000 m, is completed with wire-wrapped screens and is gravel packed. To achieve the desired flow rates, considering fluid characterization and reservoir parameters, downhole electrical submersible pumps (ESPs) (Izetti, Ronaldo, et al, 2014) were selected as the artificial-lift method to be used for single bore and Multilateral (MLT) wells (Dahle, B. et al, 2013) for the Peregrino field. In addition, booster pumps are installed at the platforms.…”

Peregrino is an offshore oil field (block BM-C-7) located east of Rio de Janeiro, Brazil in the southwest part of the Campos Basin area. The oil field was discovered in 2004. Statoil Oil and Gas, Brazil has been operating the Peregrino Feld since 2008. The unconsolidated reservoir (Carapebus formation) shows a mid to high permeability and produces heavy oil.The lower completion design requirements called for a screened completion with long openhole horizontal gravel packs for sand control and production optimization throughout the life of the field. Horizontal openhole lengths ranged from 800 m to 2,300 m for Peregrino producers. To date, 28 producer wells have been drilled and completed with horizontal gravelpacks. Since wells are not free flowing, artificial lift is required, and electric submersible pumps (ESPs) were chosen to perform the artificial lift; therefore, the upper completion architecture was designed with workover capabilities so that the pumps could be changed out as needed.In order to maximize reservoir drainage, to save the platform's slot availability, and to optimize ESP efficiency, Statoil planned to drill and complete dual horizontal multilateral wells with horizontal gravel packs on each branch that would have the capability for selective production from each lateral section.For Well B05Y1/Y2, both branches were completed with two open holes of 1300 meters and 800 meters, respectively. These were fully gravel packed and had a Level 5 Junction installed. This paper will describe:• The target zones • The gravel-packing challenges • The completion base of design • The installation sequences • The liner-conveyed gravel-pack technique used to gravel pack the lateral bore • The TAML level 5 MLT installation • The lessons learned.The successful installation of a dual-bore horizontal gravel-pack completion with a Level 5 Multilateral System offshore was an industry first for Brazil that opened ambitious perspectives for the Peregrino field in terms of increased reservoir drainage that would improve the oil-recovery factor, and thus, the economic gains. This first multilateral well in offshore Brazil is part of the operator's increased oil recovery (IOR) efforts for the Peregrino field. This is also the first multilateral well in Brazil with gravel packs in both branches.

Intelligent well completions are complex design integrated packages that includes flow control tools, zonal isolation devices, downhole monitoring systems, control, and emergency shut-in systems. This complete package allows for local automation and optimization of multi-lateral reservoirs or target developments, as well as independent or remote-control operations. As part of the intelligent completion system, the downhole wet connect links the upper and lower completions providing hydraulic, electric or both linkage for power to lower completion equipment. This paper proposes a downhole electric Wetconnect concept that differs from current downhole methods in that it is conformal, nonmetallic, has a multishell-core structure, and self-healing capabilities that allow the structure to be restored once the electric contact is disengaged by removing connecting pin. This paper presents the construction, working principles and assessment of the unique electric connector and describes initial literature review from lab study on synthesis methods. The procedure of developing the multishell-core connector is challenging and comprises selection, synthesis and interlacing of various layers with different properties. Metallic and Nonmetallic conductors, including powders, liquid metal, carbon materials, are anticipated to be employed as the connector’s core, which will be protected by dielectric layers. The material for the dielectric layers will be selected depending on temperature resistance and required thickness. The outer layers or shells can have cleaning and autonomous self-healing characteristics against both mechanical or electrical damage, by including microcapsules or employing the vascular network. Furthermore, self-healing elastomers are being studied for the outer most layer of downhole Wetconnector. Non-Metallics for conducting core are carbon-nanotubes and graphene-based conductors, and like traditional metal wires, now have electrical characteristics of their metallic counterparts, as well as several benefits, such as resilience to severe temperatures. A highly stretchable and heat-resistant material will be chosen as the dielectric layer from a range of commercially available elastomers and other silicone compounds. Due to high cost of constructing a vascular network, microcapsules containing healing agents are preferred in terms of self-healing characteristics of the outer layer. It is possible to create a self-healing elastomer that combines the unique qualities of high stretchability and universally autonomous self-healing. The key to this design is the synergistic interaction of several dynamic bonds, such as disulfide metathesis, strong crosslinking H-bonds, and weak crosslinking H-bonds. The paper introduces concepts and presents preliminary lab study of novel multishell-core flexible self-healing nonmetallic electric connector. The development plan includes electric connection evaluation, along with self-healing characteristics and resistance to water penetration under hydrostatic pressure. It is anticipated that when the tubing is redeployed, the intelligent well completion incorporated with this novel connector will allow for multiple orientation agnostic disconnect/reconnect of the upper completions and lower completions in a multi-lateral well configuration.
