Gbaran Ubie Phase Two
Phase Two of the Gbaran-Ubie project aims to sustain natural gas supplies to the Nigerian Liquefied Natural Gas (NLNG) plant and the Gbaran-Ubie domestic power plant (IPP).

|Design production:||215 kboe/day (100%)|
Shell took final investment decision on the Gbaran Ubie Phase Two project bundle in June 2013.
The Gbaran-Ubie Phase Two project bundle consists of five gas supply and infrastructure projects which are critical for the continued gas supply to the Nigeria Liquefied Natural Gas (NLNG) plant and the Gbaran-Ubie domestic power plant (IPP): 1) Gbaran Ubie 2A (Gbaran, Koroama and Epu) 2) Gbaran Ubie 2B (Kolo Creek Deep) 3) Soku NAG Compression 4) Soku Pipelines 5) Bonny NAG Minor Reservoir Development.
The expected peak production from these projects is 215 kboe per day (100%) with the majority of the new production coming from Gbaran-Ubie 2A and 2B.
The Gbaran-Ubie 2A project will add new infrastructure to develop 1.3Tscf of non-associated gas (NAG) to sustain production at the Gbaran Ubie central processing facility, located in the Niger Delta.
It builds on facilities completed under the Gbaran Ubie Phase 1 project in June 2010.
The new development will add production from nine new NAG wells in three fields, including one appraisal and one recompletion.
Two of the fields, Gbaran and Koroama, currently have producing assets. The third field, Epu, would be appraised and developed.
The surface facilities include 40 km pipelines, three remote NAG manifolds and other facilities to hook up the pipelines to the gas plant in Gbaran.
The Gbaran-Ubie 2B project will make use of the Shell Petroleum Development Company’s Soku Gas plant.
It will deliver additional non-associated gas for export through Nigeria Liquefied Natural Gas plant.
The new development will add production from seven new NAG wells in the Kolo Creek Deep field to the Soku Gas plant and drill one appraisal well. The surface facilities include of 51 cm (20 inch) x 40 km of pipelines, API 10000# DSS manifold/flowlines, a tie-in to existing utilities at Kolo Creek, as well as a so-called slug catcher – a plant that catches unwanted "slugs" of liquid – and tie-ins at the Soku Gas plant.
The high pressure of the Kolo Creek to Soku wells has necessitated the design, fabrication and installation of a bespoke piping class API 10000# (Duplex Stainless Steel). These standardised piping components have operating pressure limits of 10,000 psi. This piping class is the first of its kind at Shell Petroleum Development Company Ltd.
Environment and society
The project cuts across 26 communities and two states (Rivers and Bayelsa) in the Niger Delta. The project will liaise with those in local communities, giving them greater control over their own development through special agreements called global memoranda of understanding. Plans are also in place to create jobs for local people and business for local suppliers.
