THE NEXT GENERATION

PHAZER™ Product Range...

Placeholder Image-1

PHAZER™: FLEX

Vulcan's PHAZER™: FLEX Under-reamed centralizer has been designed to glide through previous cased hole restrictions and open up to provide a high level of Stand-off in the open hole.

Placeholder Image-3

PHAZER™: SUB

The PHAZER™ : SUB In-line under-reamed centralizer sub is specifically designed for passing through long sections of cased hole with annular clearances less than 0.50” with low accumulative running forces & to provide positive stand-off for good zonal isolation.

PHAZER™: SR

The PHAZER™ : SR is a one piece heavy duty centralizer that has been specifically designed for gauge hole centralization, offering 100% stand-off.

PHAZER™: Z Range

Vulcan's PHAZER: ZR RANGE is a low friction Zinc Alloy & Carbon Kevlar Composite solid body centralizer, designed specifically to reduce torque and drag in ERD wellbores.

PHAZER™: ECO

The PHAZER™ : ECO is a fabricated steel solid body gauge hole centralizer suitable for intermediate well bores.

PHAZER™: SB

The PHAZER™ : SB - API qualified range of welded & non-welded bow spring centralizers.

Vulcan Completion Products (VCP) centralizers have been designed to assist RIH by reducing drag/running forces and minimising ECD’s, whilst providing positive stand-off and the best possible conditions for zonal isolation.

​

With over 150 years’ experience in the design, API testing and International manufacturing of centralizer products, we offer a comprehensive portfolio, providing solutions for all applications.

​

Our highly successful patented PHAZER™: FLEX and PHAZER™: SUB centralizers have been engineered to fulfil the required extreme specifications for Under-reamed applications. This along with our new PHAZER™: FLEX-TT (Tight Tolerance) centralizer, now tackling annular clearances of less than 0.25” (6mm) in ultra-extreme cases, keep VCP pushing the boundaries of centralization as we know it!

​

All out testing is performed to surpass API 10D (7th Edition) and meet all the demands of our clients under-reamed wellbores.

Full test reports are available upon request.

​

VCP continue to push the boundaries of solid body centralization with our PHAZER™: Z Range of zinc-alloy centralizers combining Carbon-Kevlar™ composite material technologies, for the ultimate torque & drag reduction in both cased hole and open hole whilst maintaining OD, ZERO Wear. Specifically developed for ERD wellbores and beyond.

 

For intermediate wellbore applications, VCP offers a range of conventional welded & non-welded bow spring and solid body centralizers, also providing cost effective solutions.
