WEATHERFORD SUCKER RODSAnother Production Enhancement Solution from Weatherford

Choices in Technology For Your Sucker Rod Needs

Weatherfords artificial lift systems offer 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 RODS

Designed 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.

COROD Continuous Sucker RodsWeatherford manufactures

the COROD continous sucker rod for distinct production enhancement and cost saving advantages to various rod string applications. Unlike conventional sucker rods that are coupled

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

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

especially in directional and horizontal wells.

SPECIAL APPLICATIONS

Special applications such as highly deviated wells and heavy, high-viscosity oil production, are prime opportunities for the

high-strength, high-torque capabilities of the COROD system.

Corod is ideally suited to both reciprocating and rotary pumping applications.

API GRADE RODS

Weatherford API sucker rods are manufactured to API 11B specifications and ISO 9001/API Q1 certified in one of the most modern facilities of its type within the industry. These rods feature fully rolled, cold-formed threads designed to provided a precise, smooth, reinforced thread structure not attainable by normal machine-cut threads. Metal is displaced rather than removed, and the resultant cold working strengthens the thread root. Weatherford rods are cleaned by shot blasting to remove any scale and oxidation, then liberally coated with rust inhibitors and carefully palletized in bundles for safe transport and handling.

Grade C RodsLight-to-medium load applications in non-corrosive wells. AISI 1536 carbon-manganese alloy steel.Grade K RodsLight-to-medium load applications in corrosive wells. AISI 4623 nickel-molybdenum alloy steel.Grade MD56 RodsMedium-to-heavy loads in non-corrosive wells. AISI 1541 carbon-manganese alloy steel.Grade D RodsHeavy loads in non-corrosive or effectively inhibited wells. AISI 4142 chromium-molybdenum alloy steel.Grade KD63 Rods (normally API Grade D Service) Heavy loads in effectively inhibited corrosive wells. AISI 4720 nickel-chromium-molybdenum alloy steel.API Pony RodsPony Rods from Weatherford conform to appropriate API classifications. They are manufactured under strict quality standards and from the same alloy steels as sucker rods.

T66/XD SUCKER RODS

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

These rods are manufactured with 4138M chrome-moly steel, making them capable of handling the toughest stresses. The special alloy steel provides more resistance to sulfide stress cracking than AISI 4337 nickel-chrome-moly steel used in older generation high-strength sucker rods.

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

Applications

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

Weatherford Grade T and SM sucker rod couplings are manufactured to strict quality control standards from high strength alloy steel and conform to API Specification 11B.

Weatherford Hi-T couplings are designed to carry the high torque requirements of PC pumping applications. Weatherford high-strength couplings are designed to carry the high loads of deep wells.

The threads of these couplings are cold form-rolled produced by displacement of material rather than by removal of material

as in the cut thread. Rolling the thread results in a compressive stress at the root of the thread, giving maximum strength to the traditional weak point of cut thread couplings.

Weatherford sprayed metal couplings have a corrosion resistant surface with a low coefficient of friction that reduces wear on the tubing and the coupling. This coupling is recommended for deviated wells.

Weatherford couplings are available in Standard O.D., oversized and Slim Hole configurations in sizes of 58 through 1-18.

COROD Continuous Sucker RodsWeatherford manufactures

the COROD continous sucker rod for distinct production enhancement and cost saving advantages to various rod string applications. Unlike conventional sucker rods that are coupled

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

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

especially in directional and horizontal wells.

SPECIAL APPLICATIONS

Special applications such as highly deviated wells and heavy, high-viscosity oil production, are prime opportunities for the

high-strength, high-torque capabilities of the COROD system.

Corod is ideally suited to both reciprocating and rotary pumping applications.

API GRADE RODS

Weatherford API sucker rods are manufactured to API 11B specifications and ISO 9001/API Q1 certified in one of the most modern facilities of its type within the industr y. These rods feature fully rolled, cold-formed threads designed to provided a precise, smooth, reinforced thread structure not attainable by normal machine-cut threads. Metal is displaced rather than removed, and the resultant cold working strengthens the thread root. Weatherford rods are cleaned by shot blasting to remove any scale and oxidation, then liberally coated with rust inhibitors and carefully palletized in bundles for safe transport and handling.

Grade C RodsLight-to-medium load applications in non-corrosive wells. AISI 1536 carbon-manganese alloy steel.Grade K RodsLight-to-medium load applications in corrosive wells. AISI 4623 nickel-molybdenum alloy steel.Grade MD56 RodsMedium-to-heavy loads in non-corrosive wells. AISI 1541 carbon-manganese alloy steel.Grade D RodsHeavy loads in non-corrosive or effectively inhibited wells. AISI 4142 chromium-molybdenum alloy steel.Grade KD63 Rods (normally API Grade D Ser vice) Heavy loads in effectively inhibited corrosive wells. AISI 4720 nickel-chromium-molybdenum alloy steel.API Pony RodsPony Rods from Weatherford conform to appropriate API classifications. They are manufactured under strict quality standards and from the same alloy steels as sucker rods.

T66/XD SUCKER RODS

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

These rods are manufactured with 4138M chrome-moly steel, making them capable of handling the toughest stresses. The special alloy steel provides more resistance to sulfide stress cracking than AISI 4337 nickel-chrome-moly steel used in older generation high-strength sucker rods.

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

Applications

Deep, highly loaded wells in mildly corrosive environments provided satisfactor y corrosion inhibiting practices are followed.

Weatherford Grade T and SM sucker rod couplings are manufactured to strict quality control standards from high strength alloy steel and conform to API Specification 11B.

Weatherford Hi-T couplings are designed to carr y the high torque requirements of PC pumping applications. Weatherford high-strength couplings are designed to carr y the high loads of deep wells.

The threads of these couplings are cold form-rolled produced by displacement of material rather than by removal of material

as in the cut thread. Rolling the thread results in a compressive stress at the root of the thread, giving maximum strength to the traditional weak point of cut thread couplings.

Weatherford sprayed metal couplings have a corrosion resistant surface with a low coefficient of friction that reduces wear on the tubing and the coupling. This coupling is recommended for deviated wells.

Weatherford couplings are available in Standard O.D., oversized and Slim Hole configurations in sizes of 58 through 1-18.

Choices in Technology For Your Sucker Rod Needs

Weatherfords artificial lift systems offer premium quality, high-strength sucker rods with high and ultra-high load ratings plus highly corrosion-resistant properties. These special chrome-moly/chrome-nickel alloy steel sucker rods are available in 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 hardening process incorporated into the manufacturing of these rods makes them the ultimate fatigue-resistant sucker rod.

Ordinary sucker rods tend to fail from fatigue originating at the surface under tension. The unique engineering of the EL rod puts it in a class by itself. It has a thin compression layer at its surface that remains under compression even under normal operating tensile loads. Since the 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 these rods promote reliable and long service life.

Key Benefits

Energy saving through pumping with a lighter string with no compromise in production

Higher fluid production with existing pumping unit

Reduction in the size of pumping unit with no reduction in production

Use of smaller, more economical tubing

High-Strength Sucker Rods

QUENCHED AND TEMPERED SUCKER RODS

Designed for high strength and fatigue performance, the S88 rod provides an intermediate step between the normalized Grade D and ultra-high strength EL rod. These rods are manufactured with 3130M Nickel-Chrome steel; they are quenched and tempered which results in higher toughness and a finer grain structure, making them capable of better fatigue resistance. For example, the quenched and tempered rods typically have charpy impact results in the +70 ft. lb. range, while normalized and tempered rods are typically in the 20 ft. lb. range. This added toughness of the quenched and tempered rod provides the added 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.

Maximum Stress Allowable

Sa = (T/2.8 + 0.375 Smin) SF

S87 API D rod is recommended for mild corrosive or inhibited wells; also recommended for CO2 wells (sweet corrosive environments). Manufactured with 3130 modified alloy steel.

S67 API Grade D rod is recommended for heavy duty pumping in non-corrosive or inhibited wells. This economical high strength rod is manufactured with 1029 modified alloy steel.
