ADVANCED COMPOSITE STANDOFF Produces Multilayer Structural Shells

Integrally Bonded Direct to Tubular Centralization Staggered placement to give optimal fluid bypass and ECD Very low friction coefficient High wear resistance but casing friendly Low impact geometry for restrictions / obstructions Flexibility of design for bespoke solutions Very robust Construction High Mechanical properties


What is it

Multilayer Composite Centralizer (MCC) (Patent Application 1215868.9 PCT/E82013/057416)

1. Wear Resistant Zirconia Composite Layer 2. Structural Carbon Fiber and Kevlar Mat 3. Structural Carbon Fiber Mat 4. SMC Carbon Fiber Spacing layer 5. Structural Carbon Fiber Mat 6. Carbon Fiber Adhesion Mat

Integral Bond to the pipe with a High Adhesion Epoxy Resin


Production, Installation and QC Shell Production - Under Controlled Factory Conditions Multilayer lay up with structured and directional fiber and surface designed to meet environment demands Enhanced Quality Control Good output through Resin Transfer Molding (RTM) process


Production, Installation and QC Installation Surface Preparation Innovative surface preparation, NO Sandblasting units to move Minimum Anchor profile 40 Micron Adhesion to substrate > 40 MPa


Production, Installation and QC Installation Pipe Bond Injection - Place Pad on Tubular Bonding Agent delivered in 2K cartridges (Perfect stoichiometric ratio) Cartridges are loaded into gun

Material is injected through ports in pad


Production, Installation and QC

Installation Pipe Bond Injection Voids evicted using Vacuum pump



Installation Total Quality Control Ecographic Inspection to check for any defects between the pipe and the pad


Properties True Low Friction Coefficient, High Abrasion Resistance: MCC have a very low friction coefficient dramatically reducing torque and drag and assisting casing placement to TD. Abrasion Resistance 6 x higher than other direct to tubular solutions

Properties Adhesion - >40Mpa

Custom Designed Modified Epoxy Bonding Agent Silane Modified A component for maximum adhesion Nanomer and Nanotube fillers Resin matrix modified for tear strength & shock resistance Fast Cure Perfect stoichiometric ratio in 2K Cartridges Under Vacuum Injection process


Properties

Shear Load No failure at 100 tonnes


Properties Impact 10M Drop Ball Test No Damage


Properties Mechanical Testing In House Laboratory Ravenna

Adhesion 40 Mpa

Temperature Resistance 220 C

Compressive Strength 200Mpa

Tensile Strength 120Mpa

Impact Resistance 10m drop ball no damage


Properties Maximum Fluid Bypass: In close tolerance wells or pressure sensitive formations ,the ability to space the blades along the length of the tubular offset from each other results in minimal restriction to annular space and maximum fluid bypass = < ECD


Equivalent Circulating Density (ECD) Benefits:

Irrecoverable Pressure Loss, psf

n. 3 Spiral Blades @ 120 phased from each other

n. 4 Straight Blades @ 90 phased 2+2

n. 2 Spiral Blades at 180 in the same circumference

Properties


Non-Metallic inert composite material MCC is entirely non-metallic and consequently inert avoiding any risks of galvanic corrosion of or metallic debris into the well bore

Millable and Drillable Material MCC is millable and drillable in the same manner of wellbore formation allowing milling operations without the risk of running into metal collars

Properties

Casing-Friendly Material: MCC wears casing at a factor 10 times less than that of steel

Flexible Geometry and Placement The specific geometric shape and design of MCC is unlimited and is custom designed for each customers requirements and can be placed at any location on the tubular


Well Design Aids

CentraDesign - Centralizer Placement Software The software calculates centralizer placement using any combination of holes, pipe sizes and centralizers of one or more types. Given desired standoff, it calculates centralizer placement; given centralizer placement, the program calculates the resulting standoff.


Well Design Aids

TADPRO Torque and Drag Model Torque and drag problems are very common during drilling, cement, completion, and work over operations. Excessive torque and drag in the borehole will result in buckling, failure of pipe or incomplete operations. TADPRO aids in the calculation of torque and drag along drill strings or casings for various operations.


Advantages & Applications

Staggered placement to give optimal fluid bypass Very low friction coefficient High wear resistance but casing friendly Low impact geometry for restrictions / obstructions Flexibilty of design for bespoke solutions Very robust Construction High Mechanical properties

Lean profile / Close tolerance ECD Issues Differential Sticking Sidetracks & Multilaterals Expandables Predrilled & Slotted Liner ERD Wells Restrictions
