◆ Production environments include oil, gas, gas lift and all flooding and injection operations.
◆ Available with or without control-line porting. Multiple ports are available if required.
◆ Energy Systems designs for minimal overall height and maximum access. This translates into costs savings and safer operating conditions for the production operators.
◆ Utilizes Energy Systems’ proprietary interference and elastomer seals and elastomer seal compound.Is available with metal-to-metal sealing if required.
◆ Certified to API 6A, Appendix F, PR-2 plus additional cycle testing as required by CEPAI.

ELECTRIC SUBMERSIBLE PUMP COMPLETIONS
Developed for ESP or ESPCP applications. Energy Systems has standardized on penetrator options to fulfill all the Operator’s requirements without losing sight of the need to maintain a cost-effective system.

Features and Benefits
◆ Available up to 5,000 psi wells and completion sizes up to and including 4 1/16″.
◆ Designed for Class 1 Division 1, non-Class 1 Division 1, or simple cable packoff penetrator options.

◆ Suitable for sweet or sour and corrosion environments.
◆ Production environments include oil and are compatible with injection operations when corrosion may be an issue.
◆ Available with or without control-line porting. Multiple ports are available if required.
◆ Utilizes Energy Systems’ proprietary interference and elastomer seals and elastomer seal compound.
◆ Certified to API 6A, Appendix F, PR-2 plus additional cycle testing as required by CEPAI.

TUBING-LESS COMPLETION/FRAC FLOW SYSTEM
Developed for artificial lift applications for Rod Pumps and Progressing Cavity Pumps (PCP). To better serve the artificial-lift market, Energy Systems has added Integral Production BOPs (IPBOP) to our product portfolio. The IPBOP allows the Operator to safely re-enter the well bore by sealing off against the rods or, if the rods are parted, allows one to blind off the well bore.
Features and Benefits
◆ Available up to 2,000 psi wells and completion sizes up and including 4 1/16″.
◆ Suitable for sour, corrosive environments and when producing in environmentally sensitive areas or in close proximity to the densely inhabited areas (AA to FF).
◆ Production environment is oil but can be adapted to be suitable if adjacent injection operations create a more corrosive environment.
◆ Although independent components can be provided, the Integral Production BOP (IPBOP) can integrate the tubing head bonnet, production BOP and flow tee, or any combinations of these, in one unit.
◆ The Integrated BOP offers cost savings when compared to purchasing the individual items. In addition, potential leak paths are greatly reduced, and the overall height, which can be 50% less, is safer for Production Operators.
◆ The BOP rams have the capability to seal off from 0 to 11/2″ rods.
