Sakarya Gas Field
For many years Turkey has been conducting explorations of its Black Sea continental shelf. In 2006, the Turkish state oil company TPAO and BP drilled the HPX-1 deepwater well in the Eastern Black Sea, but has not find valuable resources.2 At around the same time, exploration started in Bulgaria and Romania. At that time, however, most international companies lost interest because the low prices of the Russian pipeline gas, relatively small volumes of the potential Black Sea fields and the difficulties associated with offshore gas production did not guarantee high enough profits.
In 2017 Turkey adopted a new energy strategy. In response to the discovery of giant gas fields in the Eastern Mediterranean off the coasts of Cyprus, Israel and Egypt, TPAO was tasked with stepping up its exploration work. Turkey purchased a geophysical survey vessel and three deep-sea drilling vessels.
In July 2020, the Turkish drillship Fatih started exploring for oil offshore Tuna-1 field in the Black Sea, off the coast of Ereğli, Zonguldak district, some 150-180 km offshore in the Turkish Exclusive Economic Zone (EEZ) near the border with the Bulgarian and Romanian EEZ in the Black Sea.These were the first explorations Ankara carried out in the Black Sea with its own drillship. After being upgraded, the vessel, launched in 2011 in South Korea, and when later on bought by Turkey renamed Fatih, is one of five sixth-generation drilling vessels in the world.
In August 2020, at a grand ceremony attended by the ministers of finance and energy and other officials, Turkish President Recep Tayyip Erdoğan announced that in the Sakarya field the drilling ship Fatih had made the country’s biggest-ever natural gas find. The volume of the reserves found is 320 billion cubic metres (bcm). Energy Minister Fatih Dönmez clarified that: "At the moment the drillings are conducted 3,500 metres below the sea level. The depth of the sea here is 2100 metres, and we have also drilled approximately 1400 metres into the earth. However, our work here is not finished and we will drill to another 1,000 metres depth."
The name "Sakarya" given to the field was not chosen by chance. It is associated with the battle near the river Sakarya in August 1921 of the national forces led by Mustafa Kemal Atatürk against the Greek army, which is considered a turning point in the Turkish War of Independence. A famous poem by the Turkish poet with nationalist and Islamist backgrounds Necip Fazıl Kısakürek is also dedicated to the battle. The announcement of the discovery deliberately was made in the same month as the battle. In addition to this, President Recep Tayyip Erdogan stated in a umber of speeches relating to the country's economic situation and the exchange rate of the Turkish lira that now Turkey is fighting a new, this time economic, War of Independence.
Sakarya Gas Field is located within the Sakarya Gas Field Block C26 in the western Black Sea, approximately 170 km offshore from Filyos, Zonguldak, at a depth of approximately 2,200 m, within the Türkiye exclusive economic zone.
Turkish Petroleum Corporation (TPAO or Project Owner) has been established in order to perform hydrocarbon exploration, drilling, production, refinery and marketing activities on behalf of the Turkish Republic with the Law no 6327, in 1954.
On 12th March 2019, Turkish Petroleum Offshore Technology Centre (TP-OTC or Project Executor) was founded upon a Resolution of the Board of Directors of the main company TPAO. The name TP-OTC was registered on 2 April 2019 following this resolution, and the company was structured specifically for the conducting of maritime operations.
TP-OTC, 100% owned by TPAO will be conducting Project Management and Engineering, Procurement, Construction and Installation (EPCI) for the Sakarya Gas Field Development Project (SGFD Project or the Project) which has been initiated by the TPAO to extract, transport to shore and process the natural gas discovered in the Sakarya Gas Field, in the exclusive economic zone of Türkiye, off the Western Black Sea Region, and the natural gas reserves to be discovered through the ongoing exploration. TP-, 100% owned by TPAO will be conducting Project Management and Engineering, Procurement, Construction and Installation (EPCI) for the Project.
The SGFD phases are as follows:
Phase 1: Involves natural gas production with the subsea production system (SPS) from 10 wells in the Sakarya Gas Field. The gas is transported onshore through an approximately 170 km long, 16-inch (40.64 cm) diameter steel pipeline, processed at the Onshore Processing facility (OPF), and delivered to the Petroleum Pipeline Corporation (BOTAŞ) via the existing 36 km Western Black Sea Phase - 1 Pipeline. OPF has a daily production capacity of up to 10 million standard cubic meters (Sm3 ). The infrastructure for Phase 1, including the SPS, SURF (Subsea Umbilicals, Risers, and Flowlines), and OPF, has been installed. The first gas arrival onshore was achieved in 2023, with an initial production of 2.8 million Sm3 /day. Currently, the production capacity has reached over 6 million Sm3 /day.
Phase 2 (the Project): 13 additional wells are planned for the Sakarya Gas Field, with 2 connecting to the existing subsea production system and the remaining 11 linking to a new subsea production system to be installed and will be processed within a floating production unit (FPU). The gas from these wells will be transported to the OPF or processed in the FPU before being sent onshore via approximately 170 km, 16- inch steel pipeline to BOTAŞ. Phase 2 aims to boost total production capacity to 20.5 million Sm³/day, adding 10.5 million Sm³/day to the current capacity. The gas will be delivered to the national grid via the 175 km Western Black Sea Phase - 2 Pipeline to be built and operated by BOTAŞ.
Phase 3: TP-OTC plans to continue natural gas production in the Sakarya Gas Field by drilling approximately 44 additional wells and processing the extracted gas using a new Floating Production Unit (FPU). This phase aims to bring the total number of wells to around 67 across all planned phases, with a projected maximum raw gas production capacity of 46.5 million Sm³/day. Currently in the design stage, Phase 3 is expected to commence in parallel to Phase 2 execution.
Offshore exploration activities, which were accelerated in order to increase the rate of meeting Türkiye's increasing oil and natural gas demand with domestic production, gave its first results with the natural gas reserve detected in the Sakarya Gas Field in 2020.
The SGFD Project is the first deepwater gas field discovery and the biggest natural gas reserve in the country. Within the scope of the Project, an annual production of 3.5 billion m3 will be achieved in Phase 1, followed by an annual production of 14 billion m3 in Phase 2, and 30% of Türkiye's total consumption will be met. It is estimated that the project will start production in 2023 and the natural gas needs of approximately 2.5 million households will be met in Phase 1. With the realization of the Project, Türkiye will be able to use its own resources in the near future, and thus, will decrease the share of energy in total importation significantly and make great contributions to the country’s economy.
The development of Sakarya is
underway and TPAO antcipate first gas in Q1 2023.
The current total TPAO gas resource estimate for the three discoveries is 710 BCM (25.1 TCF)–the chart below illustrates the evolution in TPAO resource estimates.
