===Offshore oil and gas===
New detailed studies and exploration shows that the Seychelles potentially have large off-shore [[petroleum reservoir]]s which are yet to be discovered. Drills have proven the presence of:

# Oil-prone [[source rock]]s containing Type II [[kerogen]] in coaly deltaic shales of the Middle Jurassic and in marine shales of the Upper Jurassic;
# Mixed source rocks bearing Type II/III [[kerogen]] in deltaic marine shales of the Lower Cretaceous that are II correlative of oil-generating shales in Somalia;
# Gas-prone sources containing Type I [[kerogen]] in Upper Triassic fluvial shales and Paleocene marine shales, the latter being correlative of oil and gas generating source rocks of the Deep Continental Shelf trend of the Bombay High Oil Province offshore west India;
# Evidence of hydrocarbon generation and migration with well shows, such as 0.7 ml benzene in DST-1 of Reith Bank-1, 10,010 ppm of 99.8% n-C4 headspace gas coincident with as small fault in the same well and 20% petrol vapours at an immature level of volcanics in Owen Bank A-1;
# Clastic reservoirs with measured porosities up to 22% in the Early-Middle Jurassic;
# Sealing [[Lithology|lithologies]] occur both locally in syn-rift, and regionally in post-rift sequences;<ref>[http://www.sib.gov.sc/pages/invopp/PotentialProjects/OilExploration.aspx Seychelles Investment Bureau Petroleum Exploration Opportunities] {{webarchive|url=https://web.archive.org/web/20110829085926/http://www.sib.gov.sc/pages/invopp/PotentialProjects/OilExploration.aspx |date=2011-08-29 }}.

# An extensive seismic dataset, plus a variety of remote sensing data have been collected which bolster the well data by confirming the presence of:
# A variety of trapping styles, dominated by tilted fault blocks, stratigraphic pinchouts and reefs;
# Multiple heating events, with the principal event post-dating trap formation; and
# Hydrocarbon generation and migration with the presence of: a) numerous DHIs on seismic, including gas chimneys, flat spots, bright spots, phase changes and chemosynthetic reefs; b) gas sniffer anomalies, involving ethane/iso-butane in the southeast and propane/normal butane/total hydrocarbon in the north and northeast; c) UV fluorescence anomalies, especially over the wells and in the southeast; and d) 4 types of beach-stranded tar that correlate to the local source rock stratigraphy.

However, to date all exploratory and stratigraphic test wells (a total of 9 since the 1970s) in the Seychelles have failed to find commercial hydrocarbons.  The most recent wildcat by Enterprise Oil in 1995 detected gas but failed to find hydrocarbons.

Several oil and gas exploration companies are active in the Seychelles offshore. These include East African Exploration (EAX) (a subsidiary of [[Afren]]), Avana Petroleum (a subsidiary of [[Vanoil Energy]]) and [http://www.whlenergy.com.au/ WHL Energy].

Beginning at the turn of the millennium the Seychelles Petroleum Company (SEPEC) started to develop the first fleet of modern petroleum double-hull tankers, with five vessels, which was completed by late 2007/early 2008 with the possibility to build more in the near future. The Seychelles President claims that this has opened the door to a new industry for his country and encouraged economic growth by further removing over-reliance on traditional trades like fisheries and tourism, which is now falling rapidly as the country's main income but nevertheless, has experienced significant growth in recent years.<ref>[http://www.sokodirectory.com/index.php?page=13&general=18 Soko Directory Investing in Seychelles].

The country has also increased its capacity for wind power, with windfarms on [[Romainville Island, Seychelles|Romainville Island]].
