Facilities Monitoring Solution

Along with providing optimization at the well level with automation tools, eProduction Solutions also provides tools for operations optimization. By providing up-to-the-minute information about your field, coupled with advanced analysis capabilities, the tools assist in making sound decisions related to field and platform operations.

Well and Facility-Site Intelligence with the Facilities Monitoring Solution

eP's solutions provide hardware for facility monitoring and process control for production and test separators. eP offers two solutions for well and facility site monitoring.

EXS-1000

eP's EXS-1000 is for use in automating oil and gas production wells and other general purpose applications requiring small to medium I/O point counts. Its electronic circuit boards are conformally coated for protection in extreme corrosive, humid and temperate environments.

The EXS-1000 design is based on 25 years of experience in providing process controllers for use in harsh environments along with quality controlled manufacturing practices. This design provides high reliability for even the most extreme conditions.

The EXS-1000 is a cost effective production automation controller designed for simple applications as a stand alone unit, or for more complex applications that involve control, communications, and alarming.

Startup is easy using the keypad/liquid crystal display or Windows based configuration management software. No special programming knowledge is required to apply the automatic alarm based control functions.

The EXS-1000 is designed for easy communications to host computers and DCS systems using either Modbus RTU, Modbus ASCII, or eP's own 8500 protocol.

The basic RTU measures 8"x7.5"x2.5" and may be mounted standalone on any control panel or optionally packaged in a NEMA 4 enclosure for outdoor service.

The EXS-1000 is suitable for applications such as well injection, well disposal, tank, and compressor monitoring.

CS7X

The CS7X is an Internet ready, modular and scalable distributed control system designed to provide real-time process control and monitoring of oil and gas production facilities. An integral web server supports direct viewing of process data using off-the-shelf browsers such as Internet Explorer or Netscape. A flash file system supports FTP file transfer of system configuration and HTML files.

Supported applications include valve and motor control, AGA3/AGA8 gas flow calculations, continuous loop PID control, and emergency shut down capabilities. High availability is achieved by redundant processors, hot swappable components, global database architecture and multiple communication channels. I/O modules are available in either a 6U rack or DIN rail mount configuration.

The eP CS7X is used for applications such as well testing, platform monitoring, and injection manifolds.

Desktop Intelligence with the Facilities Monitoring Solution

The production operations software displays data from all aspects of the field. Rather than display data points as they are returned from the RTU or PLC, the data is grouped into a hierarchical structure of facilities, tanks, separators, and wells that accurately represent the field for the user to monitor, control, and analyze field operations.

Field Monitoring

A user of this application can get up-to-date information about the current level of production from facilities, and compare it to well production information from well testing and well monitoring. The user then has immediate material- balancing information.

When a user sees a significant change in production for the field or a particular facility, he/she can "drill down" to the well level to see where the change is originating. Then with other available modules he/she can analyze reasons for the production change at the well level.

Facility Monitoring / Control

The production operations software advanced alarming features provide the ability to act on alarm states. For example, when a tank level passes a preset point, the software can shut down all wells feeding that tank, present an alarm on the screen, and even call or page the operator responsible for that tank.

Temperature, pressure, ESDs, tank level, and flow rates are tracked and trended, and alarm points are set to alert operators of pending problems. The daily reports provide the operator with a snap shot of the day's well production and performance. Downtime reports allow personnel to set priorities of which wells need attention based on downtime associated with each well and the downtime information is used to accurately measure individual well production.

Well Testing

The desktop solution provides an easy way to configure test facilities. The user can add new wells to the system, and the time, order, and frequency of tests are easily configurable for automatic, semiautomatic, or manual well testing systems. Intelligent sequencing allows operators to cycle critical wells through well testing more often than non-critical wells in an automatic well test system. The time consuming task of well test evaluation is minimized with automatic validation of well tests, which validates obviously correct well tests based on user parameters.
