First phase of Nasr offshore field commissioned

05 February 2015

Operation expected to ramp up to full capacity by end of 2015 as contractors work on phase two

Abu Dhabi has commissioned the phase-one facilities on its offshore Nasr oil field development after completing the installation of early production facilities.

Field operator Abu Dhabi Marine Operating Company (Adma-Opco) pumped the first oil from the field on 24 January and plan to ramp up production over the course of the year.

The first well flowed at 6,000 barrels a day (b/d) and Nasr is expected to hit production of 22,000 b/d by the end of 2015.

The engineering, procurement and construction (EPC) contract for Nasr phase one was awarded to India’s Larsen & Toubro in July 2011 and the company appears to have delivered the project on schedule.

Nasr phase one facilities include two wellhead towers accommodating oil producing wells, a manifold tower, solar powered control systems, subsea in-field and export pipelines, water injection, fibre optic cable, brown field modifications at Umm Shaif and Total Abu al-Bukoosh (ABK) complex.

The facilities are remotely operated from Umm Shaif super-complex, with oil from Nasr field is exported via a 20-inch subsea pipeline to Total ABK facilities for processing and to Das Island for storage and export.

Larsen & Toubro fabricated the production facilities in Sohar, Oman, and transported to Nasr for installation during 2014.

Adma-Opco has proceeded with phase two – the full field development – at Nasr, awarding the EPC contracts during 2014.

The $792m package one was awarded to Abu Dhabi-based National Petroleum Construction Company (NPCC), while package two was won by a consortium of South Korea’s Hyundai Heavy Industries (HHI) and US-based KBR for a value of $1.94bn.

Phase two will add seven new wellhead towers, a super-complex with oil processing, gas lift and utility facilities, bringing the field’s production to 65,000 b/d by a target of 2018.

France’s Technip was awarded the project management consultancy (PMC) deal for the project.

The development forms part of Adma-Opco’s plan to add 300,000 b/d of offshore capacity from three new fields, including Nasr, Satah al-Razboot (Sarb) and Umm al-Lulu.
