Production Volume: 37.4 million tons per annum

+++ Description

The sixth largest oil field in the world, the field is 80% depleted
New technologies (horizontal drilling, sidetracking, extended reach drilling, hydraulic fracturing) have been applied to boost the active well stock almost to 8 000

+++ History

1964 - The field was discovered
1969 - Production began
1999 - TNK-BP began its operations in the field

2010 - Automated well control pilot project launched

+++ Other Information

Since development work began at Samotlor a total of 2 086 well clusters have been built. This approach resulted in the field having an unusually large number of idle wells. Since TNK-BP took over operations, however, a program of well interventions has reduced the idle well stock by 39% to its current level of about 2 109.
In turn, new technologies (horizontal drilling, sidetracking, extended reach drilling, hydraulic fracturing) have been applied to boost the active well stock almost to 8 000. In addition, a development program has been implemented at the Ust-Vakh acreage, with 283 wells drilled and reserves of over 50 million tons brought on stream.
