Ostrovo (island)
river island in Serbia
Ostrovo or Ostrvo (Serbian Cyrillic: Острово or Острво; meaning "island" in Serbian) was the largest Serbian river island on the Danube, with an area of 60 km2 (23 sq mi).
Characteristics
It was 20 kilometres (12 mi) in length and 3 kilometres (1.9 mi) in width. Today it is no longer an island but peninsula, which is connected to the southern bank of the Danube. Ostrovo lies east of Belgrade, near Kostolac, and is heavily forested. It has given its name to a village of Ostrovo in municipality of Kostolac. The southern arm of Danube around Ostrovo is called Dunavac.
Natural gas
In the early 2000, natural gas reserves were discovered on Ostrovo. Potential reserves were estimated at 200 million cubic meters with the possible production of 10,000 cubic meters per day for 12 years. Profitability index was estimated to 1:7 and the extraction could start in 2001. Paraffin petroleum reserves were also discovered.

Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Oct 30, 2025. The linked authority identifier is Q1760168. Authority coordinates are 44.710, 21.120. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2000 and 2001.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
