WellPilot® Optimization Controller for Rod Pumping Features

How does it work?

The controller gathers data from the well through load and position sensors and uses it to calculate pump fillage and optimize production on each stroke. This information is used to minimize fluid pound by stopping or slowing down the pump at the assigned pump fillage setting. By using the unabbreviated application of the wave equation, the well can be controlled with unprecedented accuracy. That accuracy also enables real-time and historical production measurement for up to 120 days stored in the controller.

Getting started is easy. The new intuitive interface is easy to use and allows the user to quickly start optimizing the well.

Upgrade Capabilities

As your needs develop, the WellPilot controller grows. Because of the expandable design of the unit, it can be upgraded with additional features as you need them. Some of these features are listed below:

• Real-time inputs from an infrared water-cut meter coupled with our daily fluid production measurement provide accurate and instantaneous production well testing
• Fluid-level measurements from a portable or permanent acoustic sounding device (ASD) provide real-time data which can be logged for pressure build-up analysis and real-time calibration for fluid level control
• Real-time electronic flow measurements at the wellsite
• Measure and track chemical use and inventories in real time at the wellsite

Packaging

The unit is packaged in a new custom red polycarbonate enclosure design that is virtually indestructible. An illuminated power switch externally mounted on the door means there is no need to open the panel to the electronics section to turn the WellPilot controller on or off. An easy-to-read enhanced graphics display and keypad makes it simple to setup, optimize, and troubleshoot your well.

Upgradeability–The WellPilot central processing unit (CPU) board can be installed in earlier versions of our Model 2000 and ePIC™ RPCs. The footprint of the board mounting locations and connectors make it very simple to upgrade to the latest in technology and use the existing enclosure, display, radio, and cables.

Connectivity

The WellPilot controller supports the following:

• Ethernet interface that can be used for remote flash firmware upgrades, debugging, or host interface using IP enabled radios
• Serial interface for radio communications to host management systems
• Expansion serial port for scanning external Modbus devices
• USB on board for high speed connectivity and data storage
• Control area network (CAN) provided for future connection to infrared water-cut meter
• Bluetooth^®2 provided for future connection to an acoustic sounding device
• SD memory card slot for upgrading operating system and applications in flash file system

Getting Started

Since the WellPilot RPO is an open system and both backward and forward compatible, you can implement it in existing automated fields. The unit uses standard load and position sensors and can even be retrofit into existing Model 2000 and ePIC controller housings. The RPO can communicate across all standard communication channels so existing communication networks can be used.

The WellPilot controller simplifies the complex matter of optimizing the well and alleviates the difficulties in implementing a new system. Its open system and extendible design assure compatibility with current and future systems and applications. The menu system on the unit assures that the user can easily follow the steps to configure, run, and troubleshoot the system.
