[Indonesia] Jangkrik

All the gas in Jangkrik

Image

Hydrocarbon production in Indonesia mainly occurs in the Muara Bakau exploration block (55 per cent Eni-owned), with 10 subsea wells operating in the Jangkrik gas field and connected to the Floating Production Unit (FPU). The fields within the Muara Bakau exploration block, in the offshore Kutei Basin, are at a depth of about 400 metres and 70km from the East Kalimantan coast.

“Jangkrik” means cricket in Indonesian; crickets being small insects able to jump very high, allowing them to move rapidly. The aim was for the project to progress quickly and uncover large reserves – expectations that have so far been met. The project has progressed with excellent time-to-market, ahead of schedule, and in synergy with the existing Bontang terminal and other adjacent gas discoveries. On 22 June 2017, we sent the first shipment of Liquefied Natural Gas (LNG) produced by the field – a consignment of 22,500m3 from the liquefaction plant in Bontang, East Kalimantan, headed for Bali.



From exploration to production

Our activities are focused on the area off the coast of the East Kalimantan province, the area off the coast of the island of Sumatra and the onshore/offshore areas of West Timor and West Papua, with a total of 13 exploration blocks. Our exploration and production activities are governed by Production Sharing Agreements (PSAs). In December 2019, Eni divested to Neptune Energy Group Limited a 20% interest in the East Sepinggan block. Eni will retain a 65% interest and the operatorship.

The majority of production derives from the Eni-operated Muara Bakau exploration block (Eni 55%), where the Jangkrik gas field is located. Production comes from twelve subsea wells connected to the Floating Production Unit (FPU). After being processed by the FPU, the gas produced is transported via a pipeline to the onshore plant connected to the East Kalimantan transportation system, and is then taken to the Bontang liquefaction plant. The gas is sold under a series of long-term contracts, both to the Indonesian state company Pertamina and to Eni itself, which markets it in Asia. The development activities focused on the Merakes offshore gas project in the Eni-operated East Sepinggan exploration block (Eni 85%).

In December 2018, the development plan was approved by the country's authorities. The project entails the drilling of 5 subsea wells that will be connected to the floating production unit (FPU), where the gas from the Jangkrik production field will also be stored, and from which it will be discharged. After being processed by the FPU, the gas will be transported via a pipeline to the onshore plant connected to the East Kalimantan transportation system, and then taken to the Bontang liquefaction plant or sold on the domestic spot market. Start-up is scheduled for 2020.

The exploratory activities were successful, resulting in the discovery of Merakes East in the Eni-operated East Sepinggan block located off the coast of the country. In May 2018, we won a 100% stake in the East Ganal exploration block, in the deep waters of the Kutei Basin, near the Muara Bakau block. In 2019, Eni was awarded the West Ganal exploration block (Eni operator with a 40% interest) located in the deep water Kutei Basin, effective since January 1, 2020. The block includes the Maha discovery and other exploration potential areas, where development activities will be supported by the synergies with existing facilities.

Technologies

The Jangkrik project took on two challenges simultaneously: the construction, in Indonesia, of all the modules for gas treatment and processing (topsides facilities) in a single large Integrated Topside Module (ITM); and the building of the Floating Production Unit (FPU) in Korea. The FPU travelled from the Korean construction site to the Topside Facilities construction site in Karimun, Indonesia. There, in December 2016, the ITM was loaded on to, and integrated into, the FPU. This solution reduced project times by more than three months compared to conventional installation by individual module. These engineering and operational decisions validated our vision and our ability to construct ever-larger processing modules onshore, before transferring and integrating them into the FPU.

An FPU is completely different from a standard FPSO. Calculating the strain on the FPU’s superstructure is highly complex because allowance must be made for the FPU warping (due to wave motion) and for ITM loading conditions, as well as for the FPU’s relative narrowness and small size.

Eni: Jangkrik FPU vessel ready to sail to Muara Bakau block offshore Indonesia
21 MARCH 2017 - 10:40 AM CET

San Donato Milanese (MI), 21 March 2017 – Eni announces that the naming ceremony of the “Jangkrik” Floating Production Unit (FPU) vessel was held today at Saipem Karimun Yard, Tanjung Balai Karimun, Indonesia by H.E. Minister of Energy and Mineral Resources of the Republic of Indonesia Ignasius Jonan. The FPU shall operate in the Muara Bakau PSC located in the Kutei Basin, in the Makassar Strait offshore for the “Jangkrik Complex Fields”.

The Floating Production Unit will now sail to its final destination where, once in position, will commence mooring and hook-up operations.

The project foreseen the First Gas within three and half years from the sanctioning. The FPU will be located in strategic position that will also allow the prompt development of nearby discoveries in a region rich of gas resources.

The newly built FPU has a gas processing and export capacity up to 450 million standard cubic feet per day (mmscf/d); ten production deep-water subsea wells will be connected to the FPU. The gas, once processed onboard the FPU, will then reach using a new dedicated 79 km pipeline and a new Onshore Receiving Facilities, the East Kalimantan Transportation System and the Bontang gas liquefaction plant.

The Jangkrik gas volumes will supply the local domestic market, the Indonesian LNG market as well as the LNG export market providing a significant contribution to the Country’s energy needs and economic development.

Eni is the operator with a 55% stake of the Muara Bakau PSC through its affiliate Eni Muara Bakau B.V.; the other partners are Engie E&P with 33,334% and PT. Saka Energi Muara Bakau with 11,664%.

Eni has been operating in Indonesia since 2001 and currently has a large portfolio of assets in exploration, production and development. Production activities are located in the Mahakam River delta, East Kalimantan through the participated Company VICO Ltd (Eni 50%, Saka Energi 50%) operator of the Sanga Sanga PSC that provides an average equity production of 16,000 barrels of oil equivalent per day.
