* ODI's equalizer system provides a reservoir for clean motor oil, isolated from well fluids.
* A combination of multiple shaft seals and flexible elastomer barrier blocks well fluids from entering the motor.
* Flexible bag-type seal chambers provide for oil volume changes during the heating and cooling cycle yet avoid a direct well fluid-motor oil.
* A labyrinth-type chamber provides a backup system to prevent motor oil contamination in case a seal or elastomer barrier fails.
* A high-capacity thrust bearing is located at the bottom of the ODI equalizer. This bearing carries the axial thrust generated by the pump.
* A sintered bronze filter continually cleans the motor oil as it circulates through the system.
* All ODI equalizer seal chambers are available in corrosive resistant designs.

Pump Abrasion Protection

Abrasion resistance in submersible pump is critical. Sand wear can damage bearing areas with high-velocity fluids, shortening the life of a system.

With ODI system, you can choose from three levels of san protection:

Standard Protection

Every ODI centrifugal pump stage is designed with a diffuser pedestal that keeps sand and other abrasives away from radial bearing areas.

Rubber or Hard Bearing Design

For wells with more severe sand problem, ODI offers a rubber or hard bearing design that incorporates special shaft bearing to maintain radial stability. These bearings are spaced to provide continual radial support even if the impeller-diffuser bearing support has been eliminated.

Super Sand Pump

ODI's patented super sand pump incorporates the rubber or hard bearing design for radial support along with a patented axial support system. Thrust-carrying capabilities are provided even after severe sand wear has taken place. Run life in extreme applications may be doubled or triple.

Control Panel

ODI control panels are waterproof NEMA type 3 modular enclosure. The modular design separates the low- and high-voltage component for safety. Five types are available, based on the maximum voltage rating (600, 1000, 1500, 2400 and 3300 volts).

Solid-state or electromechanical motor protectors and U.L.-approved panels are also available.
Standard equipment includes:

* Three-pole fused disconnect or circuit breaker.
* Contrator.
* 110 volt control circuit.
* Start mode selector and pushbutton start.
* Inverse time characteristic overload relays.

Power Cable

Power cables are offered in AWG sizes from #6 to #1 and with galvanized or Monel armor.

Selection of power cable is based on well conditions such as temperature, gas, and pressure.

ODI's selection offers multipe types of cable specially designed to perform reliably in well conditions and harsh environments normally found in submersible pumping operations.

Variable Motor Speed Controller

When changing reservoir condition are problem, look to ODI's variable speed motor controller (VSMC) for the solution.

Built for any type of environment, from desert heat and dust to freezing cold and rain, ODI's VSMC give consistent, year-round dependable service. A simple adjustment of the frequency setting varies flow rate and pump discharge pressure to match your changing reservoir conditions, eliminating costly system change-outs over the life of the well.

Field Accessories

Transformer
Regardless of primary voltage, ODI can provide the transformers to meet the requirements of any cable and motor. Any transformer - bank of single phase, three phase auto, dual wound, compatible for variable-speed motor controllers, step-up, or step-down - can be found with just one telephone call to your professional ODI sales engineer.

Tubing Head
Built especially for submersible pumping applications, these heavy-duty steel tubing heads give consistently dependable service. Whether the application requires mandrils and pigtails or sealing and support for cable and tubing, ODI has the products.

Vented Junction Box
Recommended for all submersible installations, this product protects the control panel from gasses that migrate up from the well. As a point of connection for downhole cable to surface cable, the vented junction box makes safety and installation easy.

Drain Value
Pulling a wet string of tubing can increase rig time and cause hazardous working conditions. The drain plug, contained in the drain valve and placed two or more tubing joint above the pump, can be severed. When a bar is dropped from surface, all liquid is released within the tubing.

Check Valve
When a downhole submersible shuts down, the fluid in the tubing string falls back through the pump, causing the pump shaft to backspin. A broken shaft can result if the control panel is not set properly and the unit restarts while the pump is backspin. A check valve installed in the tubing beneath the drain valve protects your investment by holding the liquid in the tubing and preventing the pump from going into backspin.
Combination is Available.

AUTO FLOW VALVES (ZENITH OILFIELD)

Typically installed in wells produced by electrical submersible pump (ESP) in situations where the well has the ability of natural flow without artificial lift assistance, Zenith Auto Flow Valves facilitate significantly increased oil production by allowing continued flow to surface when the pump is switched off.

By rerouting flow around rather than through the non-operational ESP, thereby eliminating the associated restriction and providing pump protection, significantly increased oil production can be realised.

In addition, the Auto Flow Valve provides enhanced pump protection through sand diversion by preventing tubing solids descending into the pump on shut-down, defending against pump damage.

The Auto Flow Valve solids management system automatically and immediately diverts sand and debris to the annulus when the ESP is switched off, preventing the back-flow of sand clogging of the ESP stages.

Y-BLOCK BYPASS SYSTEMS (ZENITH OILFIELD)

The Y-block offsets the ESP in the well bore to allow straight line access through the bypass tubing for logging or other operations below the ESP pumping system.
The Y-block has a single upper connection and two lower connections; one for the ESP string, the other for a swivel assembly or lower nipple.
Cable grooves are provided for protection of the ESP cable and auxiliary control lines, all of which are secured with cable clips to prevent damage during deployment and operation.

Gaining access below the Electrical Submersible Pump (ESP) without the need for workover is becoming essential; the only way to achieve this is to install an ESP Bypass System (or y-tool). As increasing reservoir performance targets are being introduced, knowing how your reservoir is performing with artificial lift becomes more and more crucial.

Bypass systems are mature technology and little had progressed in their design for almost 20 years. However, Zenith ESP Bypass systems have been re-engineered to overcome problems inherent in other manufacturers’ systems.

An alternative regular bypass system can double the installation time of the ESP assembly; resulting in the rig being on location longer than required, as well as time-to-production delays.

Zenith downhole completions are designed to achieve simpler, safer installation of the system; rig time savings of more than 50% on average competitor ESP bypass installation times can be achieved.

Zenith ESP bypass completions unique system design also allows for thermal expansion of the ESP assembly preventing subsequent damage which may be detrimental to the continued operation of the ESP, maximising pump protection.

DUAL PUMP SYSTEMS (ZENITH OILFIELD)

Dual Boost ESP Systems

For wells that have lower productivity index values and require a large draw-down to overcome high back-pressure.

Two Electrical Submersible Pumps (ESPs) are combined in series, sharing the number of stages and required horsepower. Pods are used to configure two ESPs in series, the lower ESP boosting the intake pressure of the ESP above it. The configuration enables two smaller ESPs to perform the job where a single large ESP would normally be impracticable due to casing size, horsepower or shaft strength limitations.

If a single pump will not produce to surface then a third Electrical Submersible Pump can be included in the well completion as a redundancy measure for the failed pump. The Zenith Auto Flow Valve ensures that the lower pumps can be run without having to produce through the upper pump stages. The valve opens and closes automatically depending on which ESP is running.

Dual Zone ESP Systems

Dual zone well completions enable production from multiple zone wells. A dedicated Electrical Submersible Pump for each zone gives independent control of draw-down (zonal isolation). This allows improved zone management, prevents cross-flow between zones, allows improved water management and enables individual production well tests on each zone independently. If used effectively during field planning, these systems can decrease the number of wells required to be drilled.

Dual zone systems are available in two configurations:

Commingling Systems

Combines production from dedicated ESPs for upper and lower zones.

Dual Concentric Systems

Dedicated ESPs for upper and lower zones that isolate zone contribution to surface production facilities.

Dual Back-Up ESP Systems

For wells with high workover costs or difficult access. In the event of an electrical submersible pump (ESP) failure, a back-up ESP already deployed in the well can be immediately turned on to maintain production and minimise the effect on oil well performance. The second ESP is suspended below the upper ESP with a bypass assembly. The bypass tubing provides a production path for the lower ESP.

Normally the upper ESP is run first to prevent temperature effecting the backup system runlife. The lower ESP can be appropriately sized to accommodate changes in well performance such as decreasing reservoir pressure or increasing water cut.

Replace the Y-block with the Zenith Auto Flow-Through tool for automatic switching between upper and lower ESPs. The Auto Flow-Through also prevents circulation from upper to lower ESP and vice-versa, and provides pump protection from descending solids on shut-down.
