    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 wells current state

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

    Designing the artificial-lift system based on the wells 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.

    Selecting the right lifting configuration and system for a specific well or field requires an in-depth analysis of well conditions, field and client requirements, equipment capabilities and associated costs. Weatherford specialists bring together their expertise across all forms of lift to determine the most cost-effective solution and system/equipment match for maximum performance and production enhancement.

    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.
