ULTIMATE DRAG AND TORQUE REDUCTION 

Thousands of field runs worldwide have proven that the

Spir-o-lizer's advanced metallurgy and design are reducing 

both drag (sliding forces) and torque by typically 40%

compared to other solid/rigid centralisers.

This reduction in drag is proving invaluable in getting casing,

liners, and screens to bottom with ease, in demanding and 

tortuous wells.

In addition, Operators are reporting a 95% success rate when

rotating liners during clean up and cementation when utilising 

Spir-o-lizers.

In many cases, utilising Spir-o-lizer, costly high torque

connections are proving to be over specified.

 MAXIMISED FLUID BY-PASS 

 Fluid by-pass has been maximised to reduce resistance,

 increase mud sweep and optimise subsequent cement 

 placement. Downhole hydraulics are minimised to reduce

 pressure on your wellbore formation and aid in the

 prevention of mud and cement losses.

Our innovative self-cleaning blade design (patented) 

 minimises potential solids build up and packing off in

deviated applications.

 IMPROVED HOLE CLEANING AND CEMENT 

 PLACEMENT 

 Eliminate laminar flow. Even without rotation, the relieved 

angle blades induce turbulent flow for improved cutting and 

filter cake removal, in preparation for radial cement 

 placement. Due to the performance of the Spir-o-lizer tool,

 remedial cementing operations are minimised.

COMPUTER SOFTWARE PROGRAM 

 Downhole Products 3D Spacing, Torque and Drag Software

 Program offers Customers computer simulated predictions,

 prior to performing actual well bore installation of casing,

 liners and screens.

 EXCEPTIONAL WEAR RESISTANCE 

The Spir-o-lizer's resistance to abuse is unparalleled due to

 its resilience and ductility. Field runs have proven that the

tools ability to resist wear in both cased and open hole will 

ensure maximum standoff throughout the string.

 EXTENDS CASING LIFE 

The Spir-o-lizer is unique, as it offers an extension to casing 

 life by delaying the corrosion cycle, via the introduction of 

downhole cathodic protection.

UNIQUE NON SPARKING ALLOY 

 Recommended for safe use in hazardous environments.

 Aluminium or steel do not meet this criteria.

STOP COLLARS 

Spir-o-lok Stop Collars are manufactured from different 

 materials. Our Spir-o-lok DI stop collar offers a 20 Ton axial 

 holding force for today's more demanding wells. We utilise

stainless steel set screws for chrome pipe applications, to

eliminate carbon steel impregnation.

 DESIGNED TO REDUCE OPERATING COSTS 

Track Record of Reliability. 99.5% success rate.

Operators save costly rig time by virtually eliminating 

 missruns, even in the world's most demanding and 

extended reach wells.

 Further cost savings are achieved by pre-installation of 

Spir-o-lizers prior to shipping. ISO 9001 Accreditation ensures a quality product and 

service.

PEN-O-TRATORTM

n NEW SLICK BODY ELIMINATES 

SOLIDS BUILD UP 

The slick body design has eliminated 

 potential areas which can trap solids

and cuttings

§ INTEGRAL FLOAT VALVE - OPTIONAL

Positive seal PDC drillable spring

operated non-return poppet valve.The phenolic material valve is

Designed to withstand high

temperature, large volumes of 

fluids pumped at high flow 

rates. Suitable for both high

and low pressure conditions

n RUN WITH TORQUE AND DRAG 

 REDUCING ZINC ALLOY SPIR-O-LIZERS 

TO OPTIMISE PERFORMANCE 

The ultra low friction Spir-o-lizer will 

minimise drag and maximise the

rotational ability of the Pen-o-trator 

and tubular string that follows

n EASY DRILL-THRU CAPABILITY – PDC, OR ROLLERCONE BIT 

The high strength profiled alloy nose

will anchor even in uncured cement 

to facilitate ease of drill out 

n INTERCHANGEABLE COMPONENT 

TECHNOLOGY This tool can be readily factory 

assembled to suit variable

configurations and dimensions
