All rights reserved.2When 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 asystematic 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 receivedControlling 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 flowIntegrating optimizationOnly 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.MonitorAnalyzeWork FlowQuantifyControlMeasureArtificial Lift Production OptimizationSystematic approach to artificial-lift solutionsSelecting the right lifting configuration and system for a specific wellor 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 todetermine the most cost-effective solution and system/equipment matchfor maximum performance and production enhancement.Values represent typical characteristics and ranges for each form of artificial lift. Parameters vary according to well situations and requirements and must be evaluated on a well-by-well basis.2011 Weatherford.

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.PRO/KC is a registered trademark of Permian Rod Operations.2011 Weatherford.

All rights reserved.5Progressing cavity pumping (PCP) systemsWe 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 PCPapplications. 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.Progressing cavity pumpingDrive heads –Electric –Hydraulic Pumps–Conventional–Extreme conditions –Insertable Rods–COROD ? continuous –SuckerAccessories–DuraSeal rotating stuffing box –HiPer nitrile elastomer Services–Agitating autoclave Controllers –Gauges ? mPOD ?? sPOD ?–WellPilot VSDSoftware–LOWIS software ?

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 deepwaterapplications.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.
