Centek Group - Excellence to the core

Centek was founded in 2001 and is now one of the leading manufacturers of casing centralisers used in oil and gas operations to position pipes down the drilled hole prior to cementation.

Centek operates globally, throughout Europe, the Americas, Asia-Pacific and the Middle East, working with major oil companies such as Shell, BP, ExxonMobil, Maersk, and all national oil companies. The company has a strong and close association with Halliburton, one of the largest oil field services companies in the world.

In 2008 Centek won the Queen's Award for Enterprise for outstanding achievement in international trade and followed this by winning the award again in 2009, and then once more in 2014 for continuous product innovation and development.

Centek carries out all manufacturing and quality control in-house. The company employs 153 people in Newton Abbot, Devon, UK, exports to over 50 countries and holds patents in all developed oilfield countries. Centek Group opened a US manufacturing subsidiary in June 2012 based in Oklahoma City, Oklahoma, US. The 80,000ft2 factory is fully self-sufficient in all aspects of centraliser manufacture with its own heat treatment and laser cutting plants. Centek now has the largest centraliser manufacturing capacity in the world following the expansion of its Newton Abbot factory in 2014.

Centek emphasises product quality and customer support, and 75% of its sales are repeat orders from existing customers. Centek has achieved ISO 9001-2000 and API SPEC 10 D certification, both essential competencies in the oil industry.

Centek is at the forefront of centraliser design and manufacture. The revolutionary Centek S2 centraliser is a single-piece unit with an integral bow to end-band design. Manufactured from a single piece of heat-treated steel, it maximises standoff. The S2 has zero start and running forces, which reduces drag. This allows pipe rotation if reaming is necessary or once the string has landed to aid cementation.

The Centek S2 Centraliser

The S2 gives unmatched flexibility and is designed to compress virtually to pipe OD with no permanent set occurring, and then spring back to its design diameter. This is a significant improvement on older centraliser designs, which are suitable for use in vertical wells, but are susceptible to mechanical failure in the deviated, horizontal or ERD wells for which the S2 was specifically produced.

The Centek UROS Centraliser

Centek's UROS centraliser was launched in 2010 for under-reamed wells where the high points of the bows are offset alternately, which significantly reduces drag without reducing strength or centralising capability.

The Centek UROS-CT Centraliser

The UROS-CT developed in 2013 is for use with tight tolerance casings in deepwater wells where the centraliser has to compress fully to travel between tight casing strings and yet expand to the designed size once in the open hole.

The Centek S2 Hinged Centraliser

The Centek S2 Hinged Centraliser went into production in 2015 for offshore use for top-of-hole centralisation applications with oversized casing connectors. The S2 Hinged Centraliser is made from a single piece of hardened, high-grade steel with an unequalled joint strength and rapid-fit spiral pins for fitting to casing on the drilling platform or at the pipe yard. The S2 Hinged Centraliser provides a high restoring force and high standoff ratio, with no start or running forces as these centralisers are made precisely to gauge.

Centek Centraliser Sub

Centek has also introduced its Centraliser Sub designed for running as part of a tight tolerance casing string in deepwater, ultra-narrow annulus applications. Halliburton manufactures the sub and installs an adapted UROS centraliser on the sub body. In operation the centraliser can recess completely into the sub body to pass through the tightest of restrictions while protecting the bows from damage, and rotate while fully compressed with no loss of eccentricity at the end-bands.

Innovation and quality

Centek Group has a successful track record unrivalled within the Industry. Consistent performance coupled with problem-free running operations worldwide lead to consistently good primary and zonal isolation cement jobs. Centek centralisers are available worldwide through an extensive network of distributors.

There are many oilfield centraliser manufacturers, but none can rival the performance of Centek's products.
