PJSC Gazprom has achieved business oil manufacturing from the sixth block of the Achimov deposits of the Urengoyskoye discipline within the West Siberian basin.
4 oil wells within the discipline’s Block 6A have now been fired up with two cell oil remedy models. “In the longer term, a whole of greater than 40 wells might be constructed to carry out the full-scale growth of Block 6A”, Russia’s state-owned Gazprom stated in a web based assertion.
“The Achimov deposits of the Urengoyskoye discipline lie at a depth of some 3,400-3,700 meters [11,154.86-12,139.11 feet] and are characterised by an extraordinarily complicated geological construction, heterogeneity of rock formations, low permeability, excessive temperature and abnormally excessive formation stress”, Gazprom added.

“Excessive-tech options have been used to obtain cost-effective oil manufacturing from the complicated Achimov deposits. For instance, a 3D formation mannequin has been generated to present help whereas drilling horizontal wells of vital size; the multi-stage hydraulic fracturing process is used as nicely”.
Gazpromneft-Zapolyarye director-general Vladimir Krupenikov stated, “In former instances, the extraction of sources of this type was thought of to be a problem for the whole oil and fuel sector. At present, we efficiently produce hydrocarbons from the Achimov formations in varied geological circumstances. The primary-ever manufacturing of oil from the Achimov deposits of the Urengoyskoye discipline was made doable because of the event of instruments for digital modeling and drilling of high-tech wells. The expertise we gained might be used at different blocks and can assist develop complicated hydrocarbon deposits throughout Western Siberia”.
Situated within the Nadym-Pur-Taz area of the Yamal-Nenets Autonomous Space, a standard fuel producing space, the Urengoy oil, fuel and condensate discipline started producing fuel in 1978, in response to Gazprom.
Urengoy was the most important fuel discipline on the time of discovery in 1966 with preliminary reserves of 10.9 trillion cubic meters [35.76 trillion cubic feet] of fuel, in response to Gazprom.
The Achimov formations have over 1 trillion cubic meters of fuel and 400 million tons of condensate categorised as C1 (explored) below the Russian system, in response to Gazprom.
The formations first produced oil twenty years in the past below a pilot part involving Block 1A, as introduced by Gazprom July 15, 2008. Block 1A launched into business oil manufacturing three years later, as introduced by Gazprom December 2, 2011.
In 2009 Gazprom enabled pilot fuel manufacturing from the Achimov deposits by way of Block 2A, it says on its web site.
In 2021 Block 4A and Block 5A of the Achimov deposits entered take a look at manufacturing for fuel and condensate, as introduced by Gazprom on the time.
On Might 28, 2024 Gazprom stated Block 3A of the Achimov deposits had began business fuel and fuel condensate manufacturing.
“After the 5 blocks [1A-5A] attain their full capability, the general fuel output might be round 37 billion cubic meters per 12 months”, Gazprom says on its web site.
