On Tuesday, global professional services corporation Erin Energy through its subsidiary Camac Energy Gambia stated that the offshore 3D seismic survey off the coast of Gambia, West Africa has commenced.

The survey will be carried out by offshore geophysical company Polarcus using a 12 streamer 3D/4D seismic vessel Polarcus Alima, and is expected to take approximately 50 days to complete.

According to the US-based company, the survey will cover approximately 1,500km² on Erin Energy’s A2 and A5 blocks. The blocks, which are 100% owned by Erin Energy, are located 45km offshore of the Gambian coastline.

Offshore pre-drill exploration

The acquisition of 3D seismic data in this emerging West Africa margin basin will provide valuable pre-drill information that is key to evaluating the exploration potential of these blocks

In November 2014, Cairn Energy, ConocoPhillips, FAR Ltd and Senegal’s state-run hydrocarbons corporation Petrosen had discovered similar prospects from FAN-1 and SNE-1 wells in offshore Senegal.

As part of the contract, Polarcus began the 3D broadband multi-client project across the Mauritania-Senegal-Guinea-Bissau Basin offshore of Northwest Africa.

Erin Energy’s chairman and CEO Kase Lawal said: “The acquisition of 3D seismic data in this emerging West Africa margin basin will provide valuable pre-drill information that is key to evaluating the exploration potential of these blocks, which are in close proximity to recent offshore Senegal oil discoveries.

“Polarcus has a reputation for high-quality data acquisition and a commitment to the highest environmental standards, and we are pleased to be working with them.”

The asset portfolio of Erin Energy comprises nine licences across four countries covering an area of 43,000km².

Senegal’s infrastructure development

In further West African news, the Millennium Challenge Account (MCA) has recently selected a Louis Berger-led consortium for the implementation of the third phase of a major road rehabilitation programme in Senegal, the company announced this week.

The rehabilitation of the Ziguinchor-Tanaff-Kolda-Velingara section of Senegal’s National Highway 6 brings the total value of consultancy services delivered by the consortium over the three project phases to nearly $9.4 million.

Pascal Houdeau, deputy general manager of operations for West and East Africa at Louis Berger, said: “Modernisation of the bridge and of National Highway 6 — both considered to be of paramount importance for Senegal’s socioeconomic development — will significantly increase local farmers’ access to domestic and international markets.”

MCA Senegal supports private investment and entrepreneurship by developing a strong institutional framework and needed infrastructure.
