When you think of the top oil and gas nations in Africa, Ghana is not one that traditionally comes to mind, but it is one of the rising stars. In the past, Ghana has been one of the smaller oil and gas producers on the continent but that production is expected to grow rapidly over the next five years.
The organisation charged with developing the West African nations’ hydrocarbon assets is the national oil company, Ghana National Petroleum Corporation (GNPC). The rise in Ghana’s production is expected to come from the growth of existing offshore fields such as Twenboa-Enyenra-Ntomme (TEN) and Offshore Cape Three Points (OCTP).
First oil flowed from the Tullow operated TEN fields offshore Ghana to the FPSO Professor John Evans Atta Mills in August 2016. OCTP is an integrated deepwater project in Ghana split into two stages: the development of first oil, then gas deposits operated by Eni Ghana. OCTP is around 60km from Ghana’s western coast and boasts approximately 40bn m3 of non-associated gas reserves and 500m barrels of oil.
Mohammed Amin Adam, Ghana’s Deputy Minister of Energy in charge of petroleum, is confident that the country’s energy sector is on the brink of something big. He says the country can expand oil production from 180,000–-200,000bl/d now to 500,000bl/d within six years, and is targeting up to 1mn bl/d beyond that. “If we want to sustain or increase production, we will have to be very aggressive in exploration,” he said.
The average production for TEN field in 2017 was 56,000 b/d whilst production for the OCTP field is expected to peak this year at 45,000 b/d. In addition to the two established fields there are other developments that are moving ahead rapidly such as the Teak, Akasa and Mahogany East discoveries where test wells have indicated sizeable reserves.
Another major scheme is the Ghana 1000, a multi-phase greenfield gas-to-power project located near Takoradi in the western regions of Ghana. This will consist of approximately 1,300MW of combined cycle power generation technology once fully built and will support Ghana’s burgeoning domestic natural gas industry by purchasing natural gas from the Sankofa gas field, part of the OCTP field. A subsea pipeline will link a Floating Storage and Regasification Unit (FSRU) to onshore facilities which will then supply the project. It’s expected that the FSRU will start up sometime in 2020.
Ghana completed its first oil and gas licencing round earlier this year with two of the five blocks on offer being awarded. First Exploration and Petroleum Development, in partnership with Elandel Energy (Ghana) emerged as winners of block WB02 while Eni Ghana and Vitol Upstream Tano claimed block WB03. Block WB03 is located in the medium deep waters of the prolific Tano Basin, offshore Ghana. Following the success of this round, a second licensing round is being planned.
