10.11.2014 The sixth power supply block unit of Untygeisky oil production field


The sixth power supply block unit of Untygeisky oil production field At the beginning of October 2014 ROLT power systems ROLT PSG 1000 commissioned a modular gas reciprocating power plant at Untigeyskoye production field (Khanty-Mansiisk autonomous district) Gas reciprocating power plant based on gas reciprocating power unit Waukesha VHP 5904 GSID with capacity of 975 KW (electrical) became the sixth power module within autonomous power centre. The new power unit has increased the total station capacity to 6 MW (el.)

The client of the project was an owner of the oil plot - the company «KanBaikal Resources, Инк». Modular internal electrical power station at the trading has been operated since 2007, with previously commissioned gas reciprocating power plants based on Waukesha units. The decision to increase the power station was taken by the oil company management in connection with the intensification of oil production. Option for Waukesha units was made on the basis of a positive long-term operating experience of similar equipment. Indeed, associated petroleum gas is in the composition of the gas extracted at Untygeysky oil production field, which is used as fuel for a gas engine plant, has a low methane index and high content of heavy fractions. But it is the ability to work steadily on the associated petroleum gas with complex composition that gives Waukesha engines major competitive advantage.

It is needed to mark that the production field is located in conditions of eternal frost layer. It is for this reason that power is available on a single technological platform fixed on deeply bored piles. Taking into account difficult operating conditions of gas reciprocating power plants, ROLT power systems technicians had to adapt the serial structure to the aggressive climate. Thus, the gas line of the fuel system was equipped with electric heating, technological dimensions of openings and their location are optimized. In order to heat the oil envisaged for replacement the module has a separate bay for short-term storage.

ROLT engineers also conducted work on management system integration of a new power module into upper level of computer-aided process control, by including ComAp management controller into the system through asynchronous server MoxaNPort 5430 and Industrial switching unit Moxa EDS-205. Modernization of computer-aided process control allowed to realize mutual work of all power plants in the common bus with load division. Currently, control and monitoring of all equipment dealing with energy generation is performed by operators of the customer from a single control centre, located in a separate module.

According to "KanBaykal Rezorses, Inc.", further expansion of generating capacity of Untygeysky oil production field is planned by the company to be carried out in cooperation with ROLT power systems.

Note on Waukesha series VHP

Waukesha — is a world famous trademark that General Electric uses to produce industrial gas engines with capacity from 230 to 3605 kW. More than a century ago Waukesha was founded in the same city in the state of Wisconsin in the United States and has long been an independent producer of natural gas engines. In 2010 it has become part of GE Energy.

Series engines VHP (Very High Power *) have been put into mass production in the 60s of the last century. They can work on heavy types of gaseous fuel, for example, associated petroleum gas, as well as provide the reliability and high performance. VHP series engines are often used to drive reciprocating and centrifugal compressors, pumps, drilling rigs and generators. Most often, these motors are used in remote and inaccessible areas with harsh climate, such as the oil fields.
*Very high capacity

Note on Untigeyskoye production field

Untygeyskoe oil field is located in Surgut district, Khanty-Mansi Autonomous District, Tyumen region, and is part of the Vartovsky oil and gas area, Sredneobskaya oil and gas region. By recoverable reserves the production field can be classified as small, structurally – as difficult. It was opened in 1995, and in 1997 CanBaikal Resources Inc. ("KanBaykal Rezorses, Inc.") received a license for exploration and production of hydrocarbons on this oil site for 25 years, which is engaged in geological survey of subsoil, exploration and production of oil and gas, as well as an integrated operation of oil and gas fields.

Note on ROLT< power systems

ROLT power systems is an engineering company within ROLT group, activity of which was focused on implementation of projects in the sphere of power supply.
