Specialists from TMK, the global producer of pipes for the oil and gas industry, took part in lowering a tubing string with Premium-class threaded connections into a well of more than 2.5 kilometers deep, situated on LUKOIL’s Yury Korchagin oil deposit in the Caspian Sea.
The pipes were produced at TMK’s Sinarsky Pipe Plant, and the finishing threading operations were carried out at the TMK-Kaztrubprom manufacturing facility.
After the running-in, the tubing string was subjected to an air-tightness test pressure of 200 atmospheres for 30 minutes. During the testing, none of the TMK pipes was rejected as defective by the customer.
TMK is a leading global manufacturer and supplier of steel pipes for the oil and gas industry, operating 23 production sites in the United States, Russia, Romania and Kazakhstan. TMK has the world’s largest steel pipe production capacity, about half of which is dedicated to the production of high margin oil country tubular goods (OCTG). In 2010, TMK’s pipe sales totaled approximately four million tonnes, shipped to customers in more than 65 countries.
The Yuri Korchagin field is an offshore oil field in the Russian sector of the North Caspian Sea. The field is located 180 kilometres (110 mi) from Astrakhan and 240 kilometres (150 mi) from Makhachkala at a sea depth of 11–13 metres (36–43 ft).
