OSS Non-Magnetic Integral Blade Stabilizers are manufactured from Chromium Manganese Austenitic Stainless Steel.

Mechanical Properties

Tensile 120,000 psi minimum

Yield 100,000 psi minimum

Hardness 285 BHN. Minimum

Magnetic Permeability

Max 1.01

Average 1.005

Surface Treatment

OSS offers as an option, an additional treatment which, when applied to the inside diameter

and/or between the blades creates a compressive layer, giving additional protection against stress

induced cracking. This treatment is recommended when equipment is to be used in environments

with high chloride concentrations.

Stabilizer Hardfacing

For Non-Magnetic Stabilizers, OSS recommends hardface dressing type HF3000. This particular

dressing comprises tungsten carbide inserts set in a powder spray deposit, which is ideal for

abrasive formations. The 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 preheating 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


12

minimum of 97% bonding of carbide inserts is obtained. This is the OSS 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 OSS stabilizers, please specify:

1. Drill collar size and I.D.

2. Type of stabilizer (string or near-bit)

3. Type of hardfacing

4. Spiral type

5. Connection type and size

OSS Drill Collars are manufactured from Chromium, Molybdenum Alloy Steel conforming to

AISI 4145 H Modified. Fully heat treated and supplied in accordance with A.P.I. Specification 7. H2S

resistant steel is available on request.

State of the art measurement and ultrasonic techniques are used to ensure that the highest

control standards within the industry are maintained.

Quality Control and Ultrasonic Inspection

Every OSS Drill Collar is subject to full length, full section ultrasonic examination. Thread

connections are machined and gauged in accordanc e with A.P.I. Specification 7 and RP7G and are

individually examined within our own inspection department as an integral part of final inspection

procedures.

Individual characteristics of each thread such as standoff, taper, pitch, etc., are fully documented

on in-house documentation.

Thread Connections

All connections are machined to the highest possible accuracy and conform to the requirements

of A.P.I. Specification 7.

To improve fatigue resistance all connections are cold rolled and to prevent galling during make

up all connections are phosphated. Connections are coated with a thread compound conforming to

the requirements of A.P.I. and for protection against mechanical damage thread protectors are

fitted.

Precision Boring

Drill Collars are deep precision bored to ensure tight tolerances that eliminate wall thickness

variation along the bar length and drifted to A.P.I. Specifications. In addition to the standard ranges

shown on Sheet 1a, special sizes, bores, connections and lengths can be made to meet

customers’ specific requirements.


14

Surface Finish

The surface finish, linear straightness, roundness and O.D. tolerances conform to A.P.I. Specification.

Identity Markings

OSS is licensed to apply the A.P.I. monogram based on API Spec.1 marking procedure on the

Drill Collars with a unique identification serial number, O.D., I.D., size and style of connections.

Customers’ own identity markings and additional identity slots can be machined on request.

Standard ranges and sizes of Drill Collars are shown on Sheet 1a. Details of Spiral Drill

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 sleeve and pin drop into the secondary position

opening the three sub ports and diverting the downhole flow.

OSS Circulating Subs are manufactured from AISI 4145H Modified material fully heat

treated to give 285-341 BHN and are available in the same nominal diameters as standard drill

collars or to customers own specifications.

OSS offers a complete range of Hardfacings to suit all drilling conditions. Experience in the

Gulf of Thailand and China has assisted OSS to develop improvements on wear characteristics and

matrix hardness. Extensive research in-house has increased reliability in bonding.Depending on your

specific needs, OSS offers five hard-facing options for stabilizer blades:

HF 1000 Crushed Tungsten Carbides are fused together within a tough polycrystalline matrix of nickel. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

HF 2000 (Geothermal Dressing) In this hard-facing, trapezoidal tungsten carbide inserts are 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.

HF 3000 Metal Powder spray is used to fuse the tungsten carbides. This spray deposit is ideal for abrasive formations. Recommended for non magnetic stabilizers

HF 5000 (Flexicoy Technodur) Fused tungsten carbide in a nickel chrome boron matrix designed for oxy-acetylene torch application and available for components subject to high levels of wear. Flexicoy has pure nickel core surrounded by fused tungsten carbide and alloy elements for the matrix. This fused together when deposited to form a tough wear resistance surface.

HF 6000 (Flexicoy Technosphere with Diamond TCI) Diamond inserts and tungsten carbide inserts are set in a powder & Technosphere spray deposit – ideal for very abrasive formations

OSS supplies a complete line of float valves, repair kits, and puller assemblies to accommodate a wide range of drilling situations and operating conditions. These Drill Pipe Float Valves provide added blowout protection at the bottom of the drill-string, prevent flow-back when joints are added, and keep cuttings out of the drill-pipe to prevent bit plugging while making connections.

Note: It is recommended that multiple Drill Pipe Float Valves run in the same string be separated.

Model “F” Plunger Type Model “G” Flapper – Full Flow

Plunger type valve offers positive and instant shut-off. In normal drilling operations this model offers economy and durability. The piston type stops flow-back when making connections and keeps cuttings out of the drill string

Flapper style valve features an investment cast flapper. It’s quick opening for full flow through the valve. Designed for highly abrasive drilling fluids.

Model “GA” Flapper – Full Flow w/Carbide Model “FX” Plunger Type

Identical to the “G” except for a carbide orifice in the flapper. Allows differential pressure readings at surface.

For well bores with high bottom hole temperatures, hydrogen sulphide, carbon dioxide or highly abrasive hematite mud.

CONSTRUCTED FOR LONG LIFE

OSS supplied Drill Pipe Float Valves are made of low carbon steel suitable for most applications including H2S conditions. The valves are designed and constructed with a minimum number of parts-all highly resistant to wear to give long and trouble-free service.

EASILY SERVICED

Normally, the only service required is replacement of the valve seal. This can be accomplished in second with-out special tools. The valve guide at the lower end of the valve stem is simply raised, compressing the spring and allowing for removal of the entire inner portion of the valve. OSS supplied Drill Pipe Float Valves are easily installed by simply lubricating the side seals and sliding them into the cavity in the float sub or drilled out drill collar. Care must be taken in positioning the float valve in the drilling string. If it is placed too far from the top of the hole and the pipe is not filled while running in, hydrostatic pressure could cause damage to the drill pipe or the float valve. If the pipe is filled while running in, the float valve can be placed just above the bit, if desired.
