WEATHERFORD SUCKER RODSAnother Production Enhancement Solution from Weatherford

Choices in Technology For Your Sucker Rod Needs

Weatherford Artificial Lift Systems offers premium quality, high-strength sucker rods with high and ultra-high load ratingsplus highly corrosion-resistant properties. These special chrome-moly/chrome-nickel alloy steel sucker rods are availablein 5/8, 3/4, 7/8, 1 and 1-1/8 inch diameters. All sizes are offered in 25 and 30 foot lengths. Each rod is heat treated,and has pin ends machined, with API rolled threads.

EL® ULTRA-HIGH-STRENGTH SUCKER RODS

Designed to provide an ultra-high load rating and successful corrosion-resistant qualities, EL rods are Weatherford's premium line of high-strength coupled sucker rods. The exclusive induction case hardeningprocess incorporated into the manufacturing of these rods makesthem the ultimate fatigue-resistant sucker rod.

Ordinary sucker rods tend to fail from fatigue originating at the surfaceunder tension. The unique engineering of the EL rod puts it in a classby itself. It has a thin compression layer at its surface that remainsunder compression even under normal operating tensile loads. Sincethe compressive pre-stress protects the surface from tensile stresses,the chances of developing fatique cracks are greatly reduced.

Additionally, stringent quality control procedures employed with theserods promote reliable and long service life.

High-Strength Sucker Rods

QUENCHED AND TEMPERED SUCKER RODSDesigned for high strength and fatigue performance, the S88 rodprovides an intermediate step between the normalized Grade D andultra-high strength EL rod. These rods are manufactured with 3130MNickel-Chrome steel; they are quenched and tempered which resultsin higher toughness and a finer grain structure, making them capableof better fatigue resistance. For example, the quenched and temperedrods typically have charpy impact results in the +70 ft. lb. range, whilenormalized and tempered rods are typically in the 20 ft. lb. range. Thisadded toughness of the quenched and tempered rod provides theadded fatigue resistance needed in extreme applications.

S88 sucker rods are available in 5/8"*, 3/4", 7/8", 1" and 1 1/8"*diameters. All sizes are available in 25-foot and 30-foot* lengths.

COROD® Continuous Sucker RodsWeatherford manufactures

the COROD® continous sucker rod for distinctproduction enhancement and cost saving advantages to various rodstring applications. Unlike conventional sucker rods that are coupled

every 25 or 30 feet, continuous sucker rods require couplings onlyat the top and bottom of the rod string-regardless of well depth. Withfewer joints, this solid length of steel is lighter and enhances tubing

life due to a more uniform contact between the tubing and suckerrod. It also addresses many premature tubing wear challenges,

especially in directional and horizontal wells.

SPECIAL APPLICATIONSSpecial applications such as highly deviated wells and heavy, high-

viscosity oil production, are prime opportunities for thehigh-strength, high-torque capabilities

of the COROD® system.

Corod is ideally suited to both reciprocating androtary pumping applications.

API GRADE RODSWeatherford API sucker rods are manufactured to API 11B specificationsand ISO 9001/API Q1 certified in one of the most modern facilities ofits type within the industry. These rods feature fully rolled, cold-formedthreads designed to provided a precise, smooth, reinforced threadstructure not attainable by normal machine-cut threads. Metal is displacedrather than removed, and the resultant cold working strengthens thethread root. Weatherford rods are cleaned by shot blasting to removeany scale and oxidation, then liberally coated with rust inhibitors andcarefully palletized in bundles for safe transport and handling.

T66/XD SUCKER RODS

The T66/XD is an extremely dependable rod designed for high-strengthservice and provides an intermediate step between the Grade D andultra-high-strength EL rod.

These rods are manufactured with 4138M chrome-moly steel, makingthem capable of handling the toughest stresses. The special alloysteel provides more resistance to sulfide stress cracking than AISI4337 nickel-chrome-moly steel used in older generation high-strengthsucker rods.

The metallurgical makeup of the T66/XD sucker rods is checkedcontinually for quality assurance. Rods are forged, normalized, andtempered, shot blasted, and pins precision machined and roll-threaded.This continuous in-process inspection confirms that only the finestsucker rods bear the Weatherford name.

Applications

Weatherford Grade “T” and “SM” sucker rod couplings aremanufactured to strict quality control standards from highstrength alloy steel and conform to API Specification 11B.

The threads of these couplings are cold form-rolled producedby displacement of material rather than by removal of materialas in the cut thread. Rolling the thread results in a compressivestress at the root of the thread, giving maximum strength to thetraditional weak point of cut thread couplings.

Weatherford sprayed metal couplings have a corrosion resistantsurface with a low coefficient of friction that reduces wear onthe tubing and the coupling. This coupling is recommended fordeviated wells.Weatherford couplings are available in Standard O.D., oversizedand Slim Hole configurations in sizes of 5⁄8” through 1-1⁄8”.

COROD® Continuous Sucker RodsWeatherford manufactures

the COROD® continous sucker rod for distinctproduction enhancement and cost saving advantages to various rodstring applications. Unlike conventional sucker rods that are coupled

every 25 or 30 feet, continuous sucker rods require couplings onlyat the top and bottom of the rod string-regardless of well depth. Withfewer joints, this solid length of steel is lighter and enhances tubing

life due to a more uniform contact between the tubing and suckerrod. It also addresses many premature tubing wear challenges,

especially in directional and horizontal wells.

SPECIAL APPLICATIONSSpecial applications such as highly deviated wells and heavy, high-

viscosity oil production, are prime opportunities for thehigh-strength, high-torque capabilities

of the COROD® system.

Corod is ideally suited to both reciprocating androtary pumping applications.

API GRADE RODSWeatherford API sucker rods are manufactured to API 11B specificationsand ISO 9001/API Q1 certified in one of the most modern facilities ofits type within the industry. These rods feature fully rolled, cold-formedthreads designed to provided a precise, smooth, reinforced threadstructure not attainable by normal machine-cut threads. Metal is displacedrather than removed, and the resultant cold working strengthens thethread root. Weatherford rods are cleaned by shot blasting to removeany scale and oxidation, then liberally coated with rust inhibitors andcarefully palletized in bundles for safe transport and handling.

T66/XD SUCKER RODS

The T66/XD is an extremely dependable rod designed for high-strengthservice and provides an intermediate step between the Grade D andultra-high-strength EL rod.

These rods are manufactured with 4138M chrome-moly steel, makingthem capable of handling the toughest stresses. The special alloysteel provides more resistance to sulfide stress cracking than AISI4337 nickel-chrome-moly steel used in older generation high-strengthsucker rods.

The metallurgical makeup of the T66/XD sucker rods is checkedcontinually for quality assurance. Rods are forged, normalized, andtempered, shot blasted, and pins precision machined and roll-threaded.This continuous in-process inspection confirms that only the finestsucker rods bear the Weatherford name.

Applications

Deep, highly loaded wells in mildly corrosive environments providedsatisfactory corrosion inhibiting practices are followed.

Weatherford Grade “T” and “SM” sucker rod couplings aremanufactured to strict quality control standards from highstrength alloy steel and conform to API Specification 11B.

The threads of these couplings are cold form-rolled producedby displacement of material rather than by removal of materialas in the cut thread. Rolling the thread results in a compressivestress at the root of the thread, giving maximum strength to thetraditional weak point of cut thread couplings.

Weatherford sprayed metal couplings have a corrosion resistantsurface with a low coefficient of friction that reduces wear onthe tubing and the coupling. This coupling is recommended fordeviated wells.Weatherford couplings are available in Standard O.D., oversizedand Slim Hole configurations in sizes of 5⁄8” through 1-1⁄8”.

EL® ULTRA-HIGH-STRENGTH SUCKER RODS

Designed to provide an ultra-high load rating and successful corrosion-resistant qualities, EL rods are Weatherford's premium line of high-strength coupled sucker rods. The exclusive induction case hardeningprocess incorporated into the manufacturing of these rods makesthem the ultimate fatigue-resistant sucker rod.

Ordinary sucker rods tend to fail from fatigue originating at the surfaceunder tension. The unique engineering of the EL rod puts it in a classby itself. It has a thin compression layer at its surface that remainsunder compression even under normal operating tensile loads. Sincethe compressive pre-stress protects the surface from tensile stresses,the chances of developing fatique cracks are greatly reduced.

Additionally, stringent quality control procedures employed with theserods promote reliable and long service life.

Key Benefits

High-Strength Sucker Rods

QUENCHED AND TEMPERED SUCKER RODSDesigned for high strength and fatigue performance, the S88 rodprovides an intermediate step between the normalized Grade D andultra-high strength EL rod. These rods are manufactured with 3130MNickel-Chrome steel; they are quenched and tempered which resultsin higher toughness and a finer grain structure, making them capableof better fatigue resistance. For example, the quenched and temperedrods typically have charpy impact results in the +70 ft. lb. range, whilenormalized and tempered rods are typically in the 20 ft. lb. range. Thisadded toughness of the quenched and tempered rod provides theadded fatigue resistance needed in extreme applications.

S88 sucker rods are available in 5/8"*, 3/4", 7/8", 1" and 1 1/8"*diameters. All sizes are available in 25-foot and 30-foot* lengths.
