Non-Magnetic Drill Collars & Products

Schoeller-Bleckmann high grade alloys P530, P550, P580, P560, and P750 are used for these very

sophisticated parts because of their proven mechanical safety and corrosion resistance. The standard P530

material has been enhanced with our P550 and P580 material. P550 has a higher chromium and nitrogen

content which provides better resistance to pitting corrosion additionally to better mechanical characteristics and

endurance strength. The new P650 alloy uses higher Mo and Ni contents to achieve outstanding mechanical

properties and corrosion resistance. Our P750 brand offers you an extraordinary competitive possibility to

common Ni-based alloys.

Schoeller-Bleckmann Non-Magnetic passes the sensitization tests as per: ASTM A 262 Practice A & E

COMPRESSIVE I.D. TREATMENT

Schoeller-Bleckmann Non-Magnetic or Steel material has a proprietary treatment to the inside

surface. The treatment imparts a compressive stress layer to a nominal depth of 4.75mm both

circumferentially and axially throughout. This substantial depth of compressive layer provides longer

lasting resistance to Stress Corrosion Cracking.

SBD Non-magnetic Integral Blade Stabilizers are manufactured from Chromium

Manganese Austenitic Stainless Steel.

Stabilizer Hardfacing

For Non-Magnetic Stabilizers, SBD recommend hardface dressing type

HF3000. This particular dressing comprises tungsten carbide inserts set in a

powder spray deposit, which is ideal for abrasive formations. Dressing

technique has been developed in-house to take full account of the chemical

composition of the material and the need for repeat re-dressings without

damage. This includes full temperature control of the parent body during the

pre-heating process and also throughout the complete dressing procedure.

Quality Assured Tools

Full quality control procedures are maintained throughout all production

processes and when HF3000 hardfacing is deposited, final ultrasonic inspection

is carried out to ensure that a minimum of 97% bonding of carbide inserts is

obtained. This is the SBD guarantee and each tool is certified to this effect.

Connections also receive full dye penetrant inspection and are finally coated

with an anti-galling treatment.

When ordering SBD stabilizers please specify:-

1) O/D, I/D + Neck O/D

medium hard formation holes are available in two types as

shown.

Stabilizer bodies are manufactured from A.I.S.I. 4145 H Modified

steel with mechanical properties in accordance with A.P.I.

Specification 7-1.

Mild steel blades are welded onto the body using strictly

controlled pre-heating, post weld heat treatment and weld

application techniques.

All areas affected by the process of welding are subject to full

non-destructive examination to assure the mechanical integrity of

the joint.

“Standard” Weld Blade Stabilizers are only available in Straight

Blade types, but can be supplied with 3 or 4 blade configuration.

Providing tools with extra bearing areas, “Standard” tools reduce

hole wall damage in soft formations and provide improved

directional control where bit deviation forces exceed the

formations ability to adequately support conventional blade

widths.

SBD HF5000 hardfacing is most commonly applied to Weld Blade

Stabilizers.

Information on SBD hardfacings can be found in this brochure

Thread connections are manufactured to A.P.I Specification 7-1

and can be produced with Stress Relief Groove and Bore Back

according to customer’s specification.

Barrel Stabilizer Sleeves

AVAILABLE FOR HOLE SIZES 8 1/2’’ – 26’’

The SBD “Barrel” sleeve system has been designed to overcome the logistics difficulties

normally associated with transportation, storage and related costs of stabilizers at the rig

site.

Developed from the original SBD rig replaceable sleeve and fully inter-changeable with

standard steel and non-magnetic mandrels “Barrel” sleeves may be used for both string

and near bit applications.

Manufactured from high grade alloy steel “Barrel” sleeves are used extensively in

directionally drilled wells where unconsolidated or badly faulted formations are being

drilled.

Field tests have shown that when used in conjunction with a mud motor and or steerable

system the long radius and constant curvature of the sleeve blades improve directional

control particularly during orientation and can reduce torque.

“Barrel” sleeves are by design easily made power tight on the rig floor by using a

conventional plate type sleeve breaker or tongs.

Features

1) Long radius constant curvature blade profile reduces

hang up, hole wall damage and increases R.O.P

2) Reduced fluctuation of W.O.B. caused by hang up

3) Reduced drilling torque

4) Improved directional control when used in a steerable

system

Stabilizer sleeves may be

hardfaced with any of SBD

dressing alternatives and

the above illustrated blade

configuration can be

incorporated in integral

blade stabilizers if required.

Hardfacing Types

HF1000

Crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size

ensures greater concentration of carbide which is ideal for soft formation drilling.

- Section through hardfacing

HF2000

Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze

matrix. This will give a greater depth of carbide coverage – ideal for high deviation

drilling in abrasive formations.


HF3000

Tungsten carbide inserts set in a powder spray deposit ideal for abrasive formations.

97% bonding guaranteed, certified by ultrasonic report. Recommended for non-

magnetic stabilizers.

HF4000

Tungsten carbide inserts (button type). The inserts have been developed to allow

cold insertion and maintain close fit. A greater concentration of inserts on the

button third of the blade and leading edge will increase surface contact to reduce

wear in highly abrasive formations.


HF5000

The oxy-acetylene process applies tough molten carbide particles of varying size

held in a nickel chrome matrix which provides excellent bonding properties and

greater surface wear characteristics are achieved. Surface hardness levels over 40

H R C. ideal for GEO-THERMAL applications over 35°C.

Hardfacing

The LaserCarb® process from Technogenia and used by Laser Cladding Technology Ltd through a partnership agreement, has been chosen by Schoeller-Bleckmann Darron as a reference for the protection of their tools.

Part of the Group www.lasercladding.co.uk and www.technogenia.com

Laser Cladding or Laser Deposition is a processing technique used for adding one material to the surface of another in a controlled manner.

A stream of a desired powder is fed into a focused laser beam as it is scanned across the target surface, leaving behind a deposited coating of the chosen material.

This enables the applied material to be deposited selectively just where it is required.

Process Advantages

Additional material can be placed precisely where desired.

A very wide choice of different materials can be both deposited and deposited onto.

Deposits are fully fused to the substrate with little or no porosity.

Minimal heat input results in narrow HAZ (heat affected zone).

Minimal heat input also results in limited distortion of the substrate and reduces the need for additional corrective machining.

Easy to automate and integrate into CAD/CAM and CNC production environments.

Capacity

External Deposit: Diameter: Up to 1000mm Length: Up to 12000mm Weight: Up to 3000kg Flat parts can also be accommodated

Internal Deposit: Diameter: >50mm

Deposit Thickness: 0.5mm to 1.5mm per layer Multiple layers can be deposited with certain materials.

Circulating Sub

The Darron Circulating Sub has been designed to achieve increased mud

circulation by placement in the B.H.A., either above the bit or down hole motor to

pump materials in case of lost circulation.

Activation is accomplished by dropping a chrome steel ball down the drill string

and then engaging the mud pumps. On application of 3000 psi fluid pressure, the

ball shears the pin holding the sleeve in its primary position. The sleeves and pin

drop into the secondary position opening the three sub ports and diverting the

downhole flow.

Darron Circulating subs are manufactured from AISI 4145 H modified material

fully heat treated to give 285-341 BHN are available in the same nominal

diameters as standard drill collars or to customers own specifications.

CHEMICAL COMPOSITION:

P530 is a special nonmagnetic, austenitic Mn-Cr-N-steel with Nickel-content of < 2%.

MECHANICAL PROPERTIES:

Following mechanical properties (tested at room temperature) are achieved by a special cold-working process over the full length of the collar:

MAGNETIC PROPERTIES: Relative permeability: < 1,001.

CORROSION RESISTANCE:

- Transgranular SCC: Prevented by special surface treatments (Hammer peening, roller burnishing, shot peening).

- Intergranular SCC: The occurance of material sensitization is prevented by quenching after warmforging.

Each collar is tested according to ASTM A 262, Pract.A and E, last edition.

NON-DESTRUCTIVE TESTING:

- Magnetic inspection: Drill collars are 100% tested by a proprietary probe-testing process using a Förster Magnetomat 1.782. (“Hot Spot” – test). Magnetic permeability of each collar is certified with the printout of probe testing.

- Ultrasonic inspection: Each collar is ultrasonically inspected over 100% of the volume according to ASTM E 114, last edition as a minimum level.

GALLING RESISTANCE:

P530 is due to the chemical composition and the special coldworking process less susceptible to galling than Cr-Ni steels.

** Please note this data may be subject to change** P530 Non-Magnetic Drill Collars meet all requirements of API Spec 7.1, last edition. All tests are carried out according to ASTM-Standards, last edition.

P550 Material Data

CHEMICAL COMPOSITION:

P550 is a special nonmagnetic, austenitic Mn-Cr-N-steel with a high nitrogen content.

MECHANICAL PROPERTIES:

Following mechanical properties (tested at room temperature) are achieved by a special cold-working process over the full length of the collar:

MAGNETIC PROPERTIES: Relative permeability: < 1,005.

CORROSION RESISTANCE:

- Transgranular SCC: Prevented by special surface treatments (Hammer peening, roller burnishing, shot peening).

- Intergranular SCC: The occurance of material sensitization is prevented by quenching after warmforging. Each collar is tested according to ASTM A 262, Pract.A and E, last edition.

- Pitting Corrosion: Due to a high chromium – and nitrogen content a high resistance to pitting corrosion is given

NON-DESTRUCTIVE TESTING:

- Magnetic inspection: Drill collars are 100% tested by a proprietary probe-testing process using a Förster Magnetomat 1.782. (“Hot Spot” – test). Magnetic permeability of each collar is certified with the printout of probe testing.

- Ultrasonic inspection: Each collar is ultrasonically inspected over 100% of the volume according to ASTM E 114, last edition as a minimum level.
