Gazprom JV completes construction of first Semakovskoye field well
RusGazAlyans, a joint venture of Gazprom and RusGazDobycha, completed construction of the first production well at Semakovskoye gas field in the Yamal-Nenets Autonomous Area of Russia (OGJ Online, June 4, 2020). Commercial gas inflow was obtained, and studies will be performed to determine the reservoir properties and confirm flow rates indicated in the production forecast. The well is 2,637 m long.
Two additional wells are built and awaiting completion through a series of tests and other process operations, Gazprom said Sept. 18. As part of the first phase of field predevelopment, 19 wells with horizonal lengths up to 4,200 m are expected to be brought onstream before 2023, allowing producers to begin developing the gas reserves contained in the offshore segment of the deposit, the company said.
RusGazAlyans was established in April 2017 to develop Parusovoye, Severo-Parusovoye, and Semakovskoye fields in the Yamal-Nenets Autonomous Area.
The aggregate amount of these fields’ recoverable gas reserves exceeds 420 billion cu m, with over 7 million tons of liquid hydrocarbons (oil and condensate). Semakovskoye field contains the largest amount of recoverable gas reserves with more than 320 billion cu m. These reserves are concentrated, inter alia, in the waters of Taz Bay of the Kara Sea.
Commercial production at Semakovskoye field is expected to begin in 2022.
