 Another Production Enhancement Solution from Weatherford 

GAS LIFT SYSTEMS

Weatherford is the leading single-source provider of artificial lift systems

worldwide and the only company to offer a completely integrated suite of

products, services and system solutions for virtually every form of lift.

INTELLIGENT SOLUTIONSWe know and understand artificial lift

processes, reservoir dynamics and

production economics. Our Artificial

Lift Technical Specialists listen to

customers’ needs and requirements,

then carefully analyze well data, systemcharacteristics, equipment capabilities, related

costs, and other critical factors to determine

the best system for optimum production

performance. Should more than one

system and solution fit the overall

criteria, we systematically evaluateevery aspect to ensure the final solution

is the one that provides the highest return for

 Surface control of production rates

 Multiwell production from single compressor

 Multiple or slimhole completion applications

 Minimal moving parts

The primary requirement for gas lift applications is an available and economical supply of pressurizedgas. In a typical gas lift system, compressed gas is injected into the casing tubing annulus throughgas lift mandrels and valves into the production string The injected gas lowers the hydrostatic

as lift is an artificial lift process that most clearly

resembles the natural flow process and basically operates

as an enhancement to or extension of that process. When

high pressure natural gas is available either through nearby

wells or a compression source, gas lift is typically the

preferred form of artificial lift.

Weatherford's McMurry-Macco™ Gas Lift Systems include

a complete portfolio of value-added products, services and

solutions for production enhancement and ultimate reservoir

recovery. Every gas lift design is complemented by anextensive range of compatible equipment and capabilities,

technical and field support, and in-depth analysis programs.

From design and well evaluation to valve spacing and

troubleshooting, Weatherford Gas Lift Systems have

proven successful in providing solutions with exceptional

economic value and operating efficiencies.

GAS LIFT VALVESStanding at the forefront of technology, Weatherford's McMurry-

Macco™ gas lift valves are used for intermittent or continuous

gas lift, and tubing or casing flow applications. A complete line

of wireline-retrievable and tubing-retrievable gas lift valves is

included. Injection-, differential-, and production-pressure

operated valves, orifice valves and specific application valves

such as pilot and constant flow valves complement this extensive

valve offering.

This comprehensive product line is available in 1-in. and 1½-in.

sizes with selected 5/8-in. OD models for slimhole applications. In

addition, all valves are offered in various materials and packing

options to match specific downhole requirements.

SPECIAL APPLICATION EQUIPMENTSpecially designed slimhole mandrels that connect to packoff

assemblies or coiled tubing strings are offered. Weatherford's

packoff equipment is made up of retrievable isolation tools set

in the tubing string and commonly used for the

installation of concentric gas lift valves, or for

isolating holes in the tubing string.

A complete line of chemical injection and waterflood

systems is also available. Chemical injection valves

are designed to control the entry of chemicals

GAS LIFT MANDRELSAs a world leader in gas lift mandrel manufacturing,

Weatherford offers an extensive family of wireline-retrievable

side pocket mandrels and tubing-retrievable mandrels. Each

family features 1-in. and 1½-in. ID pocket profiles and

includes both oval and round body designs. Configurations

and models range from forged and machined pocket designs to

high pressure solid body, and special clearance applications.

Each model can be configured with a variety of porting options

including annular, tubing, side-string, bypass, waterflood, and

chemical-treating injection.

KICKOVER TOOLS

Weatherford manufactures a full line of kickover tools used inconjunction with wireline to selectively install or retrieve control

equipment from sidepocket mandrels equipped with an orienting

sleeve. The KOT®

tool features no pinning between runs. This

unique feature allows quicker valve installation plus offers

wireline operators unlimited attempts at removing or installing

the valve without having to come out of the well.

COMMUNICATION AND ISOLATION DEVICES

As essential components to gas lift systems,Weatherford offers a completely integrated line of

communication and isolation devices in both 1-in. and

1½-in. OD models. Dummy valves, equalizing dummy
