For years, Weatherford’s Production Optimization unit has been developing the award winning LOWIS™ software for analyzing artificially lifted wells and has completed over 90,000 well installations. In addition to software, Weatherford has industry leading hardware controllers and personnel with decades of experience. LiftAdvisor service uses their experience and know-how to provide a state-of-the art surveillance and analysis service.

LiftAdvisor service supplies operators with daily web-based well status, detailed reports and an experienced analyst’s evaluation with recommendations for well operation improvements. With LiftAdvisor service, operators of all sizes can benefit from concise daily, weekly and monthly well reporting in addition to field-proven analysis services. This cost-effective service is scalable so you choose how sophisticated your system becomes.

Web-based Well Surveillance with LiftAdvisor Service

Too much data can be as bad as not enough data if you do not have the software application and the available personnel to efficiently organize and properly analyze the data. Working with multiple customers using our software solutions we have found that there are two main modes of operation, status and analysis. While a main advantage of the service is analysis–we recognize that a majority of the time users are interested in the status of their wells. The scheduled reports package is designed to fit that need. Your own web page provides the following information:

Current Well Status–Displays current alarms, along with yesterday and today’s runtime, number of cycles and inferred production results. This information is updated every hour and can be accessed anywhere there is an Internet connection. You also have an option to include a callout system. Our host software will send a text message or email notifying you that a well is in alarm state. This makes 24/7 well optimization a reality without staffing during off hours.

Weekly Snapshot Report–The focus of this report is to give you a quick snapshot of how your well is performing. This report includes dynamometer cards, current rod pump controller (RPC) set-points, cycle times and the last seven days of runtime compared to normal operation. Every Monday morning you can view and/or download this report.

Monthly Report–On the first day of every month you can download a file containing the runtime, number of cycles and inferred production for each individual day of the previous month. This allows you to trend, manipulate and archive the monthly data.

Advantages of LiftAdvisor Service

• Web-based well status
• Quick deployment
• Experienced well analysts available
• Advanced well site hardware
• Simplified communication
• No capital investment
• Scalable solution

LiftAdvisor Analysis Services

Weatherford has a knowledgeable and experienced staff of well analysts ready to assist you with optimizing your wells. You can think of it as your own analysis team available when you need them. The goal of these services is to provide you with information so you can make profitable decisions. All these services are optional so you can choose those that will provide your company the most benefits. Analysis services include:

Controller Tuning–After the system is first deployed we will remotely tune your wells. Optimal pump-off set points and idle time for rod pump will be determined. Inferred production and base runtime will also be setup.

Standard Analysis Report–With the right information, we can provide a complete analysis report. For rod pumping, this includes downhole cards, current surface and downhole components, current operating parameters and an economic analysis of energy usage.

Detailed Analysis Report–This report has all the information that is found in the Standard Analysis Report plus our analysts will further analyze the well, point out areas of concern and make recommendations based on their years of experience.

Dedicated Analyst–With this service, one of our well analysts will be assigned to your wells. Each week they will check on your wells using a combination of our industry leading software and their field experience. Our analysts will then notify you of any issues that may be affecting the performance of your wells. If you have any problems with your well, you can also notify the analyst and they will look at your well remotely and provide feedback. The goal of this service is to be proactive rather than reactive and identify problems before they become costly.

Benefits of LiftAdvisor Service

• Determination of pump condition, pump fillage, tubing anchor condition, gas compression, pump spacing, etc.
• More accurate top of stroke, RPC pump off and malfunction set-point determination
• Correct pumping unit gearbox loading, including unit unbalance and counterbalance requirements to properly balance the unit
• Accurate pumping unit walking beam (pumping unit structure) loading
• Correct peak rod stress calculations
• Correct pump displacement, which can be used to verify well testing results, as well as to track downhole pump efficiency
• Calculated fluid levels–the user no longer has to depend solely on manual fluid level tests
• More accurate calculated fluid level trends
• Calculated pump intake pressure (PIP) accuracy
• Accurate electrical cost calculation

LiftAdvisor Service Standard Analysis Report

Surface and downhole dynamometer cards Current information about each well including the latest well test data Unit loading including gearbox torque, structure load and fluid level information Rod string data including peak rod stress as a percent of allowable maximum Surface and downhole load information Pump displacement data based on surface, downhole and net pump stroke–as well as pump efficiency calculations Prime mover vs. calculated horsepower data and electro/mechanical efficiency values Calculated daily and yearly electrical costs

Detailed Analysis Report from LiftAdvisor Service

At Weatherford, we understand that a canned report does not provide enough information to truly understand the condition of your well. That is why LiftAdvisor service incorporates knowledgeable and experienced well analysts using our industry leading tools to develop in-depth and detailed reports. The contents of these reports are customized to your wells and focused on the type of information you are looking to extract. The reports include multiple surface and downhole cards, our Standard Analysis Report, cycle times and other information that conveys the analyst’s interpretation of the wells state. The recommendations included are based on the data collected from the wells, analysis software and the analyst’s years of experience. With these reports, you have the information you need to make better informed decisions for more productive, profitable wells.

Getting Started with LiftAdvisor Service

LiftAdvisor service can be as simple as web site access to your well’s current information or as complex as a package that includes a controller at the well site, communication system, web site access and a well analyst providing detailed reports of the wells on the system. The service uses an open system that can be used with existing artificial lift controllers and most communication systems, so past investments are not lost. Weatherford has years of experience in the design and implementation of remote optimization applications. Our technicians will perform a site survey and develop a system that minimizes your costs but also provides the reliability needed for your specific needs.

Minimal Investment of LiftAdvisor Service

Because Weatherford hosts the software server, your costs are minimized. While each company has their own secure system, the costs of servicing and maintaining the systems are shared. The economies of scale multiply with efficient use of computing systems, standardized communication systems and affordable wellhead electronics. This service includes software support provided by our team in Houston. Plus with Weatherford hosting your server, upgrades occur without interruption to your operations.
