Indonesian operator Medco Energi has received offers from subsea contractors for the next development stage of the Hiu satellite field in the domestic Natuna Sea Block B.

Two oil pools at the Hiu field are to be developed as subsea completions tied back to an existing production facility.

Jakarta-based contracting sources said offers have been submitted for the subsea engineering, procurement, construction and installation workscope by several companies, all of which are well-established Indonesian subsea contractors.

The precise EPCI workscope could not be confirmed as Upstream went to press.

The Hiu subsea scheme went through the front-end engineering and design phase last year.

The main Hiu field has been on stream since 2007, and is one of a series of producing fields within the Block B complex that Medco acquired in 2016 from ConocoPhillips, Inpex and Chevron.

Medco now holds a 40% operating interest and is partnered by Indonesian companies.

In 2019, the block produced 54,200 barrels of oil equivalent per day on a gross basis.

Medco said in a financial results presentation in late November 2020 that its four recent commercial exploration gas discoveries in Block B “will be fast tracked for development in 2021-2022 in parallel with the previously planned Hiu development”.

The four discoveries were Bronang-2, Kaci-2, West Belut-1 and Terubuk-5.

While Hiu and the new discoveries are all likely tie-in schemes, Medco is also developing a standalone project in Block B called Forel.

FEED work has been completed on Forel and contracting sources said previously that Medco will soon invite bids for the EPC phase of the project.

The development concept for Forel includes a leased floating production, storage and offloading vessel, a wellhead platform, a subsea connection to the FPSO and a separate flowline via a pipeline end manifold to the nearby Belanak oil and gas field also in Block B.
