Gazprom kicks off West Siberian drilling with private partner
Gazprom and Rusgazdobycha are also working together on a integrated gas processing and LNG production complex on the Baltic Sea.
A joint venture between Gazprom and its private partner Rusgazdobycha has started development drilling at the Semakovskoye gas field in Western Siberia.
Semakovskoye is the largest of three fields operated by Rusgazalyans, a 50:50 partnership between the pair formed in 2017. It is estimated to hold 350bn cubic metres of recoverable gas.
Work on the first production well at Semak- ovskoye has begun, Rusgazalyans said in a state- ment on May 29. The well has a partial horizontal gradient, with a total of length of 2,700 metres and a vertical depth of 830 metres. Its completion is expected before the end of June. Mobilisation of a rig and other equipment began in March.
The development model for Semakovskoye calls for the construction of 19 production wells, with six due to be ready by the first quarter of 2021.
As most of Semakovskoye lies in shallow waters of the Gulf of Ob, Rusgazalyans is look- ing to build two artificial islands from where deviated wells can be drilled to tap offshore res- ervoirs, according to plans filed with authorities last year. This less common method of recovery
has been used at Kazakhstan’s Kashagan project in the Caspian Sea.
Rusgazalyans also intends to construct a third well cluster onshore, along with a 7.3 bcm per year gas treatment complex. Extracted gas will be piped to Gazprom’s operational Yamburg- skoye field, situated around 45 km south of Semakovskoye.
First gas had been scheduled for 2022. The project partners have given varying forecasts for output, although they suggested in 2018 that Semakovskoye and Rusgazalyans’ two other deposits Parusovoye and North-Parusovoye could flow up to 20 bcm per year by 2030.
Rusgazdobycha is reportedly controlled indi- rectly by Arkady Rotenburg, a key Kremlin ally who also owns one of Gazprom’s main building contractors, Stroygazmontazh (SGM).
Gazprom and Rusgazdobycha are also part- nered at a project to build a new gas processing and LNG production complex at the Baltic port of Ust-Luga, predicted to cost at least $13bn. Ethane from the project is to be supplied to a nearby petrochemical plant that Rusgazdobycha plans to build on its own. ™
