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.
COILED TUBING COMPLETION
Developed to allow operators to continue production from natural-lift oil and gas wells without major workovers. Energy Systems has experienced various applications of coiled tubing, including uses as initial production tubing to replace the jointed pipe, and use as a velocity string in existing completions, being snubbed into an existing well, artificial lift, gas lift, ESP completions and dual concentric strings.
Features and Benefits
◆ Increases savings by reducing the time the drilling rig stays on location.
◆ Minimizes the tubular cost by reducing the hole and casing sizes.
◆ Faster completion than conventional rig and jointed tubing.
◆ Prevent formation damage associated with kill fluids.
◆ Available in all popular API thread and flange connections or combinations of both.
◆ Pressure ratings are comparable to rated pressure of coiled tubing.
INTEGRAL PRODUCTION BOP FOR ROD & PROGRESSING CAVITY PUMPS
Developed to support well fracturing operations in today's natural gas completion processes. In addition, the system works well for applications where high production rates deplete rapidly and a siphon string is to be added at a later date to further enhance production. The smaller tubing head flange allows for economical temporary tubingless completions and for traditional tubing completions. This type of completion eliminates the need for wellhead isolation tools and tree savers during the well fracturing job, saving time and money. The system supports standard jointed tubing or coiled tubing completions.
Features and Benefits
◆ Available up to 15,000 psi wells.
◆ Suitable for sour, corrosive environments and when producing in environmentally sensitive areas or in close proximity to the populous (AA to HH).
◆ Eliminates the need for Wellhead Isolation tools and Tree Savers reducing rental tool cost.
◆ Reduces fracturing stack rental costs because of the smaller size.
◆ Allows a siphon string to be run through the XT, landed, and packed off. The bigger-bore XT can then be removed and replaced with a more economical tree compatible with tubing size and production pressures of the flowing well.
◆ Also available for use with the DTO Wellhead System providing additional drilling time and completion savings.
HORIZONTAL COMPLETION
Developed to allow well intervention to occur without removing the XT and flowline. This allows the Operator to maintain flowline connections, thus, reducing cost associated with reconnecting the well and enabling the well to be brought back onstream quicker.
Features and Benefits
◆ Available up to 10,000 psi wells and completion sizes up to and including 9".
◆ Suitable for sour, corrosive environments and when producing in environmentally sensitive areas or in close proximity to the densely inhabited areas (AA to HH).
◆ Production environments include oil, gas and gas lift.
◆ Greatly simplifies access to the tubing string for workovers.
◆ Provides easier access for the Production Operator to the gate valves.
◆ On bigger-bore completions, can greatly reduce height required for the wellhead deck.
◆ Available with or without control-line porting. Multiple ports are available if required.
◆ Utilizes Energy systems' proprietary interference elastomer seals and elastomer seal compound and our patented metal-to-metal seal technology.
◆ Certified to API 6A, Appendix F, PR-2 plus additional cycle testing as required by CEPAI.
LARGE - BORE COMPLETION

Features and Benefits
◆ Available up to 15,000 psi wells and completions sizes up to and including 7 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 HH).

TUBING CONVEYED ESP
Developed to allow the submersible pump to be retrieved with minimal well intervention and with a coiled tubing unit. The well is produced out of the annulus; thus, the flowline stays intact during any well intervention. A recognized disadvantage of ESPs is inherent maintenance that is required on any downhole pump. This design concept allows the maintenance to occur in a fraction of the time with conventional ESP completion methods.
