Our Oilfields

Our Licence Area: Mangistau Basin, Kazakhstan  

Jupiter’s oil production is located in the Mangistau sub-basin in the southwest of Kazakhstan. The Mangistau consists of a series of onshore oil fields extending 300 km long and 100 km wide on a northwest-southeast trend. 

The basin has a historic oil production of 5 billion barrels of oil in excess. Oil was originally produced from Jurassic sandstones in simple domal traps, but more discoveries have been made in the deeper Triassic carbonates, most significantly in the dolomites of the ‘T2B’ formation.  

Jupiter Energy currently owns 100% of a 123km2 licence area, with multiple new discoveries in this area over the last 20 years. Until today, this area remains a lightly explored basin.  

Our Oil Fields 

Jupiter Energy’s oil production is housed in 3 fields in two structural areas: 

1. Akkar North (East Block)
2. Akkar East
3. West Zhetybai in the southeast

By 30 June 2025, Jupiter Energy had produced approximately 2 million barrels from five wells. Today, production is steady at around 530 barrels per day from four active wells, with the fifth well undergoing preparation for a workover to further boost output. The entire Licence Area is now almost fully covered by advanced 3D seismic, with strategic well placement on a prospective T2B Dolomite reservoir.  

Akkar North (East Block) & Akkar East  

Since acquiring its licence in 2008, Jupiter Energy has drilled six wells in the Akkar North (East Block) and Akkar East area, showing successful and consistent exploration. The first five wells, J-50 (drilled in 2009), J-52 (2010), J-51 (2011), J-53 (2012), and Well 19 (2014), all discovered oil, confirming the Licence Area’s strong potential. Our most recent well, J-57, was unsuccessful in intersecting hydrocarbons, but provided valuable subsurface data for future drilling campaigns.  

Jupiter Energy’s J-50 well, located on the Akkar North (East Block) oilfield, is classified as part of the Akkar North accumulation, meaning that Jupiter Energy and the neighbouring permit operator MangistauMunaiGas (MMG), who operate the Akkar North oilfield, develop the Akkar North accumulation under a Joint Development Plan. Meanwhile, our J-53 well has confirmed oil but is yet to complete production, representing further upside potential.  

West Zhetybai

West Zhetybai has proven oil across three wells, with J-58 currently on production. Jupiter drilled J-55 (in 2012), J-58 (2012), and J-59 (2013) on the West Zhetybai structural complex on three local closures, and all three confirmed oil discoveries. 

J-58 was successfully completed as a producer in the T2B Dolomite, showing oil pay over the whole 147m gross section with good reservoir in sporadic pods through the whole formation. These results highlight both the productivity of J-58 and the untapped potential of the wider West Zhetybai structure.
