When choosing a form of lift, Weatherford uses its extensive suite of lift offerings to design the most appropriate system for your well. For gas-well deliquification, we have developed the Unloading Selector, a simple online process that analyses the data you provide and then produces an unbiased recommendation as to which form of lift is best suited for your well. In addition we provide intelligence-at-the-wellhead with specific controllers for each type of lift and intelligence-at-the-desktop with our detailed analysis software for maximum optimization. However, optimization is more than just control and analysis. It is a

systematic approach to operating wells, managing field operations and exploiting reserves efficiently.

To that end, we provide tools to comprehensively optimize wells at an individual and fieldwide basis that follow the optimization cycle, including:

• Monitoring well activity and reservoir changes

• Quantifying data received

• Controlling well operation based on the well’s current state

• Analyzing the artificial-lift system related to the current well status

• Designing the artificial-lift system based on the well’s current and projected characteristics

• Managing operations work flow

Integrating optimization

Only Weatherford offers optimization, products and expertise for all forms of lift. We provide unbiased system recommendations based on an exacting analysis of reservoir data. Matching the system to the task ensures better control of lifting costs and enhanced reservoir recovery.

Reciprocating rod-lift systems

We combine multiple technological systems and field-experienced personnel to provide the best configurations for any field. Our rod-lift solution offers complete optimization of your well from the pumping unit and downhole pump selection through wellsite automation and data analysis. By integrating rod-pump controllers (RPCs), variable-speed drives (VSDs), remote diagnostic software and communication systems, we enable operators to effectively optimize their production.

We offer a wide range of pumping units, providing specific solutions for high-efficiency, long-stroke, low-profile and nonelectric power sources. Specific rods are available depending on the configuration of the well. Sucker rods of various strengths and composition can be considered for the particular requirements of the well. Our COROD® continuous rod is a choice for many modern rod-lift systems.

More than just offering the right pump size, we provide multiple types of downhole pumps, including insert, tubing and Fluid-Packed™ pumps. Once a pumping system is configured for a well, a WellPilot® rod pump optimization controller (RPOC) or VSD is used to control the pumping system to match inflow and production. LOWIS™ host-based software provides the detailed analysis that enables operators to fine-tune the operation of the pump, predict and react to pending problems, monitor performance of the well in real time, manage work process of well activities, and create better designs for the pumping, based on historical information from the well.

Progressing cavity pumping (PCP) systems

We offer the most comprehensive portfolio of PCP systems including an unrivaled selection and application experience.

Drive heads are available in electric or hydraulic formats, and pumps are designed for the vast differences in conditions that can be found in PCP applications. Even specific stators can be chosen based on the temperature and properties of the fluid produced.

Our new HiPer™ elastomer has extended pump life in a coalbed methane (CBM) well from 3 to more than 18 months. Our DuraSeal™ stuffing box provides the confidence required to operate your pump safely for an extended period. We have more than 500 boxes in the field, and many have been running for more than 400 days.

We provide intelligence-at-the-wellsite with our WellPilot® VSD, downhole sensors and surface instruments designed for PCP operations. Intelligence-at-the-desktop is provided through LOWIS™ and WellFlo® software that monitors, analyzes, controls and designs the lift system.

Our WellPilot VSDs prevent over torque of the rods and enable the well to be pumped at maximum rates without pumping off and damaging the pump. Downhole pressure and temperature gauges at the intake and discharge of the pump provide further precision for the controller and the well analyst to properly operate the pump. The information from the controller, gauges and other sources, such as well-testing data, are used in LOWIS software to monitor and analyze the function of the well. The data collected in LOWIS software is used to adjust the design of future pumping systems for that well. Additionally, WellFlo software provides nodal analysis for new and existing wells.

Plunger-lift systems

We offer different types of plungers from conventional to high-tech to accommodate various well conditions like high-ratio oil and loading gas wells. Our lift experts can look at the composition of the liquid and the amount of gas, pressures and well configurations to design an optimal system. In conjunction with bumper subs, lubricators, controllers and accessories, we offer complete plunger-lift systems, optimized for your success.

The recent release of our new SafetyLift™ plunger system is just one example of the innovations that we provide our plunger-lift clients. The SafetyLift plunger can effectively operate below a subsurface safety valve in deepwater applications.

Additionally, our WellPilot® plunger-lift controllers manage the release of the plunger to the precise time that the well has built enough pressure for another cycle. The controllers use pressure measurements and built-in logic to determine the best time to cycle the well. The controller operates in one of four user-selectable control modes, including A/B valve (normal mode), pressure mode, Murphy mode and 3-valve mode. Historical data are stored in the controller, including but not limited to the number of plunger travels, total plunger arrivals, plunger travel time and accumulated sales time. Additionally, LOWIS™ software provides analysis tools for the operator to fine-tune the well to deliquify gas wells and provide maximum gas or fluid production, as well as electronic flow measurement (EFM) operations.

Our gas-lift systems feature an extensive range of compatible equipment available for use with continuous and intermittent flow applications and with wireline- and tubing-retrievable deployments. Our products, including valves, mandrels, latches and kickover tools, offer the flexibility to

provide the right equipment and system solution for every gas-lift requirement. Our experience enables us to be innovative in our thinking, and our engineers are always working to improve existing designs and create new and useful tools.

For deepwater, high-pressure and highly corrosive well environments, we designed the double-valve external (DVX) side-pocket gas-lift mandrel, which is now being used in installations throughout the world.

We not only offer our experience and innovations, but we also provide support through a suite of design and analysis software to aide in the selection of valve types, port sizes, depth settings and much more. Our software is available and applicable throughout the life of your reservoir.

To enhance further your well’s performance, we offer intelligence-at-the-wellsite with controllers that can handle single or multiple wells for injection control and parameter monitoring. The solution provides access to continuous real-time data, controls the constant gas injection based on controlled set point, and supports orifice-meter and turbine-meter gas measurement. It provides a well stability profile (heading detection) and an alarming interface for a gas-lift specific control unit.

We have the most advanced software for designing, monitoring and troubleshooting production issues. With ReO® software, you can model the entire field and optimize the gas allocation across all wells for maximum production fieldwide. WellFlo® systems analysis software provides a powerful and simple-to-use standalone application to design, model, optimize and troubleshoot individual oil and gas wells. WellTracer™ technology gives you a snapshot of your well’s performance by injecting a small volume of carbon dioxide (CO2) into the gas supply to detect the presence of multiple-lift points, the depth of an operating valve and even-injection gas leaks into the production tubing. We also have industry-standard software for designing gas-lift systems and unloading modeling.

With an extensive selection of sizes and materials, plus value-added products and solutions, our clients maximize ultimate reservoir productivity and realize increased operational efficiency.

Electric submersible pumping (ESP) systems

We offer a complete solution—not simply parts and components— to enhance production over the life of a well or field, as well as improve our client’s system run-life and overall profitability. Our experienced personnel understand there is more to providing a finely tuned ESP completion than just excellent hardware. Our ESP team uses their experience in design, engineering, installation and optimization to provide a full-time ESP support structure and ensure maximum returns from your investment.

Our total solution provides wellsite intelligence, historical references and remote optimization. At times, the ESP solution can react to changing fluid levels and return to normal operations without the operator having to intercede. With the remote terminal unit (RTU) storing the short-term data and the remote software collecting, trending and providing analytical displays of that data, the user is aware of temporary changes in the system. These changes can be compared over time to identify trends that provide a method to predict potential problems and take proactive action to avoid impending expensive repairs.

Our ESP solution provides intelligent control at the wellhead, as well as monitoring, analysis and control at the desktop. The result is improved ESP performance and increased profitability. We currently have hardware and optimization software installations used in many locations around the world.

Hydraulic-lift systems

Recognized for flexibility and the capability to operate in high-volume, high-depth environments, our hydraulic-lift systems provide extraordinary flexibility in installation and operation to meet a broad range of artificial-lift requirements. Offering jet and piston hydraulic-lift systems—ranging from operating depths of 5,000 to 17,000 ft (1,524 to 5,182 m) with volumes from 50 to 25,000 BFPD—our hydraulic-lift capabilities are designed to maximize production and reduce lifting costs.

Our hydraulic jet-lift pumps provide proven performance in almost limitless applications covering a wide range of depths, volumes and well conditions. With no moving parts, our jet-lift pumps provide greater reliability and serviceability, which is a real plus in remote locations. Its shorter length also provides easier passage through problematic boreholes.

With our simple method of changing the pump size, our experts can customize your jet-lift pump to maximize your returns. This technique is accomplished through our proprietary jet-pump sizing program (JEMS), an evaluation modeling software. JEMS simulates anticipated downhole conditions and performance ranges for every possible scenario, enabling us to prescribe the precise nozzle and throat sizes. We then provide you with a performance chart reflecting the highly efficient and cost-effective system for your well.

Capillary injection-lift systems

We provide advanced chemical technology and injection services, resulting in safer and more effective production enhancement for clients worldwide—onshore and offshore.

Our chemical services group offers Engineered Chemistry® solutions for virtually any downhole condition that one encounters, and our proprietary injection equipment has been designed with safety and service life in mind.

We maximize your well’s production while protecting your tubulars—reducing your workover needs and eliminating batch treating and shut-in time. Our expertise places chemicals at the precise point in the amount needed, eliminating chemical metering and saving chemical costs.

In addition to an outstanding training program and skilled operators, there are important and unique safety features built into all of our capillary string units. Only Weatherford equips every capillary string unit with a hydraulically controlled blowout preventer (BOP), instead of a conventional single-element packoff.

In fields around the globe, production declines are not always the result of reservoir or wellbore issues. Sometimes completion factors, such as flow areas cause reduced production—and our patented internal critical velocity reduction plus (iCVR+™) and Xtra-Lift™ systems provide solutions.

These proprietary Weatherford technologies are designed for extended perforated-interval gas wells. They combine the best attributes of flow-area reduction and foam-lift assistance by reducing surface tension and density of produced water.

These solutions reduce the well’s critical velocity and improve production rates.
