This project involves the integrated development of the Jangkrik and northeast Jangkrik gas fields in Indonesia – more commonly known as the “Jangkrik Complex”.
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.
The extremely rapid development and start of production of the Jangkrik Complex project.
The first gas
In March, the FPU left Karimun (Indonesia) for Jangkrik. On 22 June, the first shipment of LNG set off for the Indonesian inland market
The FPU’s journey
The FPU leaves Ulsan (Korea) bound for Karimun
The execution stage
The construction sites open, 10 wells are drilled and sealines laid
FID approval
The final investment decision is approved
The development plan
The north-east Jangkrik field is discovered and its development plan approved
First well discovered
The first well is discovered: Jangkrik-1
Exploration block acquired
Eni acquires the Muara Bakau exploration block as operator
Workplace safety is a fundamental principle that we share with employees, contract workers and local communities. For that reason, we implement all necessary measures to avoid accidents, including organisational models to assess and manage risk, training programmes, skills development and the promotion of a culture of safety.
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.
The FPU’s journey: from construction to arrival in Indonesia.
We have launched various projects and initiatives regarding environmental protection, healthcare and educational development for local communities in areas we operate in East Kalimantan, Papua and North Sumatra. In 2018, we launched a programme facilitating access to energy and water for local communities, as well as training programmes on farming and healthcare.
