The SWITCH is designed to dramatically reduce cost (and retrofit) of how Operators deploy Dual and Multiple ESP completions by coverting any single ESP completion to a Dual ESP without changing or adding to the existing completion. Substantial savings on capital cost, operating cost, planning time and lost production time means the SWITCH is set to become the standard choice for all Dual and Multiple ESP completions.
Existing Dual ESP completions require duplicated and costly specialist equipment to accommodate the dual power cables necessary to separately control the ESPs. THE SWITCH avoids all of these costs and issues.
Dual ESP systems are supplied power through individual power cables fed from the surface - these cables penetrate the wellhead through RMSpumptools gas tight wellhead penetrators. The two cables and specialist cable protectors continue down to the ESP setting depth.
In order to provide annular isolation above the ESP‚s, a production packer is often used. RMSpumptools packer penetrators similarly maintain the critical pressure integrity of the packer. The packer penetrators transition the round main ESP power cable to a flat Motor Lead Extension, or MLE.
The MLE‚s feed into the individual motors of each ESP which can be configured in a choice of RMSpumptools, non-intervention, fully automatic ESP completion systems.
Pioneering HP/HT Product Development
RMSpumptools has leveraged its field proven technology to develop mechanical and electrical products for the next generation of HP/HT wells. With production horizons deepening, the need for higher production rates and ultimate recoveries necessitate artificial lift in order to make prospects economic. Until now, the challenge has been to find completion products capable of withstanding the harsh environments associated with the requirements of deep, hot production.
In anticipation of the next generation of high power Electric Submersible Pumps required for these applications, we have developed HP/HT packer penetrator technology rated to 8-KV, 250-Amps, while fully V0 qualified at 7500-psi differential, 225°F. This HP/HT technology has been tested independently and in conjunction with production packers to show it is fully V0 compliant (100% barrier to gas at pressure and temperature)... another industry first.
Building on this success, we are finalizing the development of a Dual Can production system capable of reliably operating at 10,000-psi differential, 300°F. This dual system uses a proprietary metal-to-metal seal to ensure complete pressure integrity over its life, while incorporating our HP/HT penetrator technology with V0 capability. This technology will first be deployed as an 8-5/8” can system capable of production rates as high as 20,000-bbl/day and will be incorporated into our full line of completion systems.
The Switch now introduces a new dimension to these established methods of dual completions. The Switch is installed on the production tubing, typically below the Pump Packer. All cable terminations are factory prepared to proprietary RMSpumptools plug and socket connectors, eliminating any field cable splicing and ensuring high integrity electrical assembly during installation.
Advancements in ESP Power Cable technology and application now provide expected life of well reliability that The Switch capitalises upon. The substantial benefits of Dual ESP completions now takes on a new and exciting dimension that will provide SUBSTANTIAL savings, REDUCED risk and greater choice for multiple ESP completions.
In order to prove the durability of our equipment throughout the lifecycle of an HP/HT well, we have undertaken a joint study with a major operator with the goal of establishing reliability as a performance specification. The end result of this process will be demonstrable proof that all components of the completion system can withstand 10-years in an HP/HT environment. This culture of reliability has always been present at RMSpumptools, which is why we are the supplier of choice for industry shaping technology.
