Gazprom neft: Record fishbone built at East-Messoyakha field


 

Yamalo-Nenets AO, February 14 - Neftegaz.RU. A unique for the industry multilateral well with 8 branch holes by the fishbone*  technology was built at East-Messoyakha field.

 

The length of the productive hole is 5.1 km, the total drilling rate is 9.1 km. The oil-saturated layer in the drilling area did not exceed 12 m. Fishbones are the trademark of Messoyakhaneftegaz. The multilateral well design increases the well productivity by 40% compared to a standard horizontal well and allows directing each branch to separate oil zones without opening sections with gas or water.
 

 The use of this technology is relevant for East-Messoyakha field’s geological structure, where reserves are located in split sandy deposits with clay bands at the depth of less than a kilometer. Last year, 131 high-tech wells were built at the field, every 4rth with using the fishbone technology. In 2019, 25 new similar wells with a large number of branch holes will be constructed at East-Messoyakha field. 

 

The East-Messoyakha field was launched by Vladimir Putin during a video conference on September 21, 2016. The 2018 East-Messoyakha output amounted to 4.5 million tonnes of oil.
 
 

* Fishbone is a multilateral well with a special trajectory - one horizontal borehole derives many branches. That makes the well look like a fish skeleton, thus the name. The well trajectory significantly increases the coverage of oil-saturated areas compared with traditional horizontal well with smaller scope of drilling activities.
