Ofon Field is an oil and natural gas field located in the Oil Mining Lease (OML) 102, about 65km offshore in the south-eastern coast of Nigeria. The reserves lie at a water depth of 40m (131ft). The OML 102 is owned by state-owned Nigerian National Petroleum Corporation (NNPC - 60%) and is operated by Total Exploration-Production Nigeria (TEPNG - 40%), formerly Elf Petroleum Nigeria.
The proved and probable reserves at Ofon are about 350 million barrels of oil equivalent. The phase 1 of Ofon Field started production in December 1997.
Phase 2 of the offshore Ofon Field development began in February 2012. It is expected to come on stream in 2014. Phase 2 will tap the undeveloped reserves at the Ofon Field. The development will mostly focus on producing natural gas. The recovered gas from the field will be compressed and transferred to the shore.
The second phase is expected to increase the production from the field from 30,000 barrels of oil equivalent per day (boepd) to 90,000boepd. The project will involve installation of four new platforms that include two production platforms, one accommodation platform for 124 people and a processing platform.
Ofon Field phase 1 and phase 2 oil and gas field development
The first phase of Ofon Field was launched in 1995. The reserves at the field were discovered using structural to stratigraphic exploration techniques. It consists of three platforms. The four-level production deck for Ofon phase I was constructed by McDermott. The 115ft x 102ft deck was built using deck/pancake technique. Total identified potential extension of the Ofon field in the southern flank in 2005.
Plans for the phase 2 extension were initiated in July 2007. The project was expected to come on stream in 2011. It has been, however, delayed for about five years. Upgrades to the three existing platforms and design of the new platforms were undertaken by Aibel.
The Ofon phase 2 will be a sustainable
