West Africa: Bioko island Malaria Elimination Project

Expanding Regional Expertise

Alen Platform
Alen Platform

Our work in the Republic of Equatorial Guinea began as a non-operating partner in the Alba field in the early '90s, giving us a longer history in the country than any other international energy company. We also have a discovery offshore Cameroon and are exploring offshore Gabon.

In 2005, we made our first operated discovery in the Alen field, located in the Douala Basin offshore Equatorial Guinea. We repeated this success with discovery of multiple oil and gas-condensate reservoirs. We’ve since converted two discoveries into producing fields.

We brought Aseng, the first floating storage and offloading vessel (FPSO) in the Douala Basin, online in 2011. This was quickly followed in 2013 by the Alen platform, a condensate recovery and gas reinjection facility. The gas reinjection system minimizes the need for flaring and maximizes condensate production from the reservoir. Learn more.

Alen Gas Monetization

In April 2019, we made a final investment decision on the Alen gas monetization project with startup planned for the first half of 2021. Gas from the Alen field will be processed through existing facilities on Bioko Island. The Alen development is the first step towards creating an offshore natural gas hub in Equatorial Guinea, which will open the potential for future monetization of additional discovered resources through existing infrastructure. Noble Energy has discovered 3 trillion cubic feet of gross natural gas resources in the Douala Basin, which positions us well for LNG sales exposure over the coming decade.

Environmental Commitment: Bioko and Biodiversity

Bettering People’s Lives means respecting biodiversity, which is especially meaningful on Equatorial Guinea’s Bioko Island. Bioko is home to an ecosystem populated with rare primates and monkey species, untouched rainforest, endangered sea turtles, and a volcanic crater.

We help fund the Bioko Biodiversity Protection Program, which aims to protect these rare species. We extended our dedication to Bioko by starting the Equatorial Guinea GrEEN Program, which brings together local children ages 8-13 for a day of environmental education activities at the Moka Wildlife Center on Bioko Island.

Investing in a Program to Save Lives and Prevent Disabilities

EG Fishing VillageA simpler “screen and treat” approach to cervical cancer could make a substantial difference in women’s health in Equatorial Guinea, thanks to support from Noble Energy for a new detection program. 

Currently, cervical cancer is one of the leading causes of death and disability among women in Equatorial Guinea. To address this issue, a new initiative conducted by Medical Care Development International (MCDI) in consultation with the Ministry of Health and Social Welfare aims to screen 6,000 women aged 20-60 years and build government capacity for further expansion of the diagnostic and treatment protocol.
