Bashneft Introduces New Pipeline Repair Technology

Rosneft Oil Company’s Bashneft has completed the first-ever repair of an operating pipeline at the Arlanskaya group of fields without stopping oil pumping. The technology involves the installation of equipment on a pressurised pipeline. Stoppers are installed on either side of the pipeline section that needs to be repaired or replaced, with a bypass (standby line) installed between them. After blocking off this pipeline section, the oil flow is diverted through the bypass.

Field trials of the new technology were conducted at one of Bashneft-Dobycha’s oil treatment units. It took 18 hours to repair and replace 75 metres of pipeline. Thanks to the new technology, oil pumping, and the production well stock operations are not interrupted when the pipeline stock is being repaired. Throughout the repair, the volume of products transported via the pipeline section exceeded 14,000 tonnes. The economic gain amounted to 18.7 million roubles.

The successful experience of repair on the pipeline while still pumping crude has opened up new technological opportunities for the Bashkir oil industry and will become relevant in pipeline sections with substantial pumping volumes. Maintaining pumping volumes during repair has a significant impact on the financial and economic performance of the plant.

Bashneft-Dobycha was formed in 2009 as an enterprise of Bashneft. Its core production activities are conducted in the Republics of Bashkortostan and Tatarstan and the Khanty-Mansi Autonomous District–Yugra and the Orenburg Region.

The Arlanskaya group of fields includes seven oil fields located in the Burayevsky, Dyurtyulinsky, Ilishevsky, Kaltasinsky, and Krasnokamsky districts of the Republic of Bashkortostan and the city of Neftekamsk. It is developed by the Arlansky oil and gas production region, one of Bashneft-Dobycha’s five production regions.
