BREGTON’s specialists have created a very useful ESP design and analysis instrument for its’ clients - a sophisticated software system – BREGTON Monitoring System for conducting a full-scale analysis of the oil well conditions.

BREGTON Monitoring System is the core of condition-based maintenance. Technologies, such as vibration analysis, motor current signature, ultrasound and oil analysis, are used to help assess machinery health and predict future failures. Prediction of failures allows maintenance to be planned on the user’s schedule, not the machine’s.

An examination of fluid dynamics within a centrifugal pump provides appreciation for the need to analyze the pump “one stage at a time.” The importance of individual pump testing is also identified.

The system includes four cutting-edge software programs: Bregton-well, Bregton-lift, Bregton-esp, Bregton-design. All these products using a method of computer modeling. Bregton-well and Bregton-lift programs are used for modeling of methods, in which the ESP motor, producing formation, and fluids are considered a complex system.

Bregton-esp and Bregton-design provide a basis for the prediction of the equilibrium point at which a particular set of equipment might operate under specific well conditions. BREGTON-design permits an analyst to compare a number of designs for desirability, while BREGTON-esp can identify possible changes in operating conditions impacting pump life.

Thus, these software instruments provide all the necessary information needed for monitoring, analyzing, and designing submersible pumps. The information is presented in a clear and concise graphical interface, that displays the maximum information needed to efficiently optimize electrical submersible pumps.

BREGTON monitoring system utilizes most up-to-date models in the software engine to accurately predict the ESP’s future performance. Developed as a user-friendly system, this software contains an intuitive workflow to navigate through the application design in a logical and concise manner. Modules define the wellbore schematic and accurately size all the down-hole and surface components.

The software simplifies the process of optimizing the equipment’s work under different conditions with extensive case comparison capability.

BREGTON ESP analysis software provides the latest information on ESP equipment and utilizes the fluid, well, and reservoir information to predict the inflow and outflow performance of an ESP system design. The software features helpful error messaging and a detailed limitation report to aid in properly selecting ESP equipment.

BREGTON software also uses animated simulations to view fluid levels in the annulus and tubing. It simulates the system condition from the start of the operation to the time when the system stabilizes and the fluid level is constant.

It also generates a well schematic diagram detailing the equipment type and the associated clearances.

BREGTON service system for improving underperforming artificially lifted wells brings the requisite measurements and expertise together—in one place, at one time—to achieve well-by-well optimization.

Bregton-lift process enables fast and clear performance evaluation of the artificial lift system and the well. The evaluation is achieved by seamlessly combining operator field knowledge with BREGTON measurement technology, services, and artificial lift capabilities.

BREGTON process measurements

Flow rate — This is the primary measurement in any well optimization program, but it is acquired in a variety of ways—with a corresponding variety of uncertainties. A consistent measurement and an understanding of its uncertainty are fundamental to analyzing well performance before and after any treatment. Measurement consistency and understanding are also the best proof of the Bregton-lift process effectiveness and value.

Vibration Monitoring System (VMS)

BREGTON can supply vibration monitoring systems (VMS), providing continuous trend monitoring for your specialized equipment. Depending on your project, the VMS system can be designed with various types of transmitter arrangement and compatible interface modules. These systems are inclusive of instrument racks, accelerometers and in-tank instrument cables. If desirable, BREGTON can also install head-plate instrument boxes with accelerometers as requested.

Pressure

Flow responds directly to changes in wellbore pressure. For improved performance, it is preferable to rely on actual measurements of downhole pressure rather than calculations. A permanent downhole monitoring service, such as the Bregton-lift system ( BLS ), allows thorough diagnosis of wellbore pressure response to the lifting system. Combined with multiphase flow measurements, a diagnosis using pump intake and discharge pressures can provide a very accurate picture of the artificial lift response. Such diagnoses have shown gains of 88% net oil through the Bregton-lift process.

Distributed temperature sensing

Fiber-optic distributed temperature sensing (DTS) technology provides measurements over the complete length of the fiber in the wellbore. The DTS system can be temporarily run within slickline using standard slickline equipment, or it can be installed permanently, using proprietary technology, in a control line.

The Bregton-lift process uses the DTS measurement to gain instantaneous information about the status of the entire well and artificial lift system. Combining this information with pressure and flow measurements enables a more efficient and precise approach to optimization. DTS technology is well suited to gas lift wells because it allows simultaneous observation of dynamically actuated hardware positioned throughout the wellbore or in multiple gas lift mandrels in the completion. In addition, DTS can identify leaks and other completion problems.
