  • Do you have a solution for production flow that does not interact with the annulus?

    Yes. We have two variations of the AccessESP system. The annular AccessESP solution draws fluid from the annulus like a conventional ESP system. The inline AccessESP solution is a shrouded system that draws fluid from a lower completion, through the production tubing, without entering the annulus.

  • What is the diameter of the AccessESP system when the retrievable assembly is removed from the well?

    The pass through diameter for the Access375 system is 3.70". The Access450 system is 4.45". The Access562 system is 5.57".

  • Can you incorporate Deep Set Sub Surface Safety Valves into AccessESP systems?

    Yes. The AccessESP system permits up to five bypass lines of up to 3/8" diameter (Access375 system). Larger AccessESP systems can accommodate additional lines.

  • Are AccessESP systems compatible with standard industry ESP gauges? If so, what measurements can be made?

    Yes. The system is compatible with gauges offered by most major ESP providers. Measurements depend on the system selected but typically include motor winding temperature, intake pressure, intake temperature, and vibration (X and Y). A tubing mounted discharge gauge can be added for discharge pressure and temperature.

  • Can AccessESP systems be run through a SSSV?

    Yes. Access375 has an outside diameter of 3.75", compatible with a 3.813" SSSV ID. Access450 has a 4.50" OD, compatible with a 4.562" SSSV ID. Access562 has a 5.62" OD, compatible with a 5.750" SSSV ID.

  • In the event of issues during the installation of the retrievable assembly, can the equipment be re-run?

    Yes.

  • Do AccessESP systems require the use of an ESP packer?

    No. A packer is not required.

  • Are AccessESP systems compatible with industry standard surface drives?

  • Is a lubricator required for installation?

    No. A lubricator is not required for installation.

  • Can AccessESP systems be installed in a horizontal or highly deviated well?

    Yes. The system can be installed with a tractor or coiled tubing.

  • Do surface drives have to be modified to run the permanent magnet motor?

    No. AccessESP permanent magnet motors are compatible with all industry standard variable speed drives.

  • Are permanent magnet motors proven?

    Permanent magnet motors have been used extensively in the aerospace, high-end automotive, machine tool, defense, and other advanced applications for over 25 years. They have an unmatched record for reliability and performance due to the simplicity of their design.

  • Why does the AccessESP system use a permanent magnet motor instead of an induction motor?

    A permanent magnet motor (PMM) uses rare earth magnets to generate an extremely strong, static, rotor magnetic field. This field is far stronger than what can be achieved with the electrically generated field of an induction motor. As a result, a PMM is capable of generating three to five times the power of an equivalently sized induction motor. In an ESP system, this offers many advantages: elimination of the need for tandem or triple motors, allowing for the required power to be delivered in one motor section; efficiencies that are much higher than can be achieved with an induction motor, particularly at other than rated speed; much higher torque  with virtually zero inrush current at startup; and far fewer parts, making it much simpler than an induction motor. PMMs are the motor of the future in the ESP industry in much the same way they now dominate other high-end applications. AccessESP has developed a unique PMM solution that is compatible with all industry variable speed drives, including medium voltage drives.

  • What metallurgy is available for AccessESP systems?

    Yes. AccessESP solutions are compatible with standard industry pumps, cables, intakes, gas handlers, VSDs, gauges, penetrators, packers, and protectors. AccessESP systems have been installed in partnership with most major ESP suppliers.

  • What changes to standard ESP equipment must be made to use the AccessESP system?

    AccessESP systems are compatible with all industry standard equipment from the major ESP providers. Depending on the power required and flow requirements, occasionally a pump and protector may be modified for through tubing deployment. This is an acceptable practice that has been approved by all major ESP suppliers.

  • What is the deepest depth the system can be installed?

    There is no practical limitation on deployment depth. Our deepest installation to date is 9,800 feet MD.

  • Can gas lift be integrated into an AccessESP installation?

    Yes.

  • Why did you change the company name to AccessESP?

    AccessESP is not an ESP or artificial lift provider. We provide a unique conveyance solution for ESPs that eliminates the need for a rig. We changed our name to reflect our unique value proposition to our clients.

  • Does AccessESP provide other ESP equipment?

    AccessESP has successfully partnered with most major ESP suppliers. We are not an ESP company. We offer a radically simplified rigless ESP conveyance solution. Our ESP partners provide the pump, intake, discharge, protector, cable, clamps, penetrators, VSD, and services to commission the ESP.

  • What production rates can I achieve with the AccessESP system?

    The AccessESP technology is limited only by the capacity of the pump. Access375 can produce up to 6,000 barrels per day with conventional ESP pumps. Access450 can produce up to 10,000 barrels per day. Access562 can produce 20,000 barrels per day.

  • Can AccessESP systems tolerate H2S, CO2, and frac sand?

    Yes. These are addressed in the job planning stage during material selection.

  • How is an AccessESP solution managed?

    There are a variety of ways a project can be successfully managed, from complete ownership of the ESP project to a sub contractor to your current ESP provider. During initial discussions the process and procedures for managing the project are clearly outlined and communicated to all parties involved.

  • What is the maximum allowable power through the wet connect system?

    The wet connect system has been qualified to 7,500 PSI, 125 amps, and 5,000 volts.

  • How does the wet connect work? What prevents wellbore fluid from contaminating the electrical connection?

    The AccessESP wet connect comprises two mating systems. The male connector is a simple component that is mounted on the permanent completion (part of the tubing string). The female connector is located on an extendible plug arm on the retrievable assembly. The design of the two components ensures a clean, robust connection through the use of a patented cleaning and sealing system on the female connector that is recharged each time the connection is made. In field tests, we have made over 50 connections on the same male/female pair with no leaks or contamination.

  • What pump sizes can be used?

    Pump sizing is dependent on the ESP design. AccessESP systems are compatible with a broad range of pump sizes that are readily available in the industry. Typical pump sizes range from the 338 series to the 562 series.

  • What type of power cable can be run to surface?

    Cables from any ESP supplier are compatible with the AccessESP system.

  • Is a workover rig needed to install the permanent completion?

    Yes. The one-time installation of the permanent completion is identical in operational processes to installing a conventional ESP. Subsequent deployments require only slickline, a tractor, or coiled tubing.

  • Can I use rig tongs to make up the permanent completion?

    Yes. Making up the permanent completion is similar to the process for making up tubing.

  • Is the downhole power cable installed or clamped with the permanent completion?

    Yes. The permanent completion installation is identical is most regards to a conventional ESP installation. The ESP provider will run cable and clamps identical to its normal operations.

  • Can the permanent completion be sealed and pressure tested?

    Yes. There are two variations of the AccessESP system. The annular AccessESP system draws fluid from the annulus like a conventional ESP system. Installing the isolation sleeve provides up to 10K PSI of isolation. This sleeve can be easily installed or removed with standard slickline. The inline AccessESP system is a shrouded system that is isolated from the annulus and can be tested up to 5K PSI.

  • What packer electrical feed through penetrators can be installed?

    We can work with any provider.

  • Can hydraulic lines and control lines be installed with the AccessESP system?

    Yes. The AccessESP system permits up to 5 bypass lines of up to 3/8" diameter (Access375 system). Larger AccessESP systems can accommodate additional lines.

  • Can an ESP packer be used with the AccessESP system?

    Yes. For 7" casing, we have designed an ESP packer with five feed throughs. For other casing sizes, conventional ESP packers are compatible.

  • What casing sizes can AccessESP accommodate?

    For Access375, 7" OD casing with a minimum 5.969" ID drift, i.e. 7" 32.0 pound casing. For Access450 and Access562, up to 9 5/8" OD casing with a minimum 8.379" ID drift, i.e. 9 5/8" 53.5 pound casing.

  • What is the pass through diameter for the permanent completion?

    The pass through diameter for the Access375 system is 3.70". The Access450 system is 4.45". The Access562 system is 5.57".

  • Can an induction motor be run with the AccessESP system?

    No. The permanent magnet motor is required to achieve the high power density, light weight, and small size required for through tubing deployment. Conventional ESP motors are far too heavy and long.

  • Can I reuse equipment that has been in operation downhole?

    It is not recommend to use equipment that has been in operation downhole, but each circumstance is different, depending on time, conditions, and other factors. Normally, backup equipment will be used.

  • What slickline gauge sizes are used for installation and retrieval of the assembly?

    The system is deployable with standard 0.125" slickline or larger.

  • What is the recommended RIH speed for slickline or wireline runs?

    Trip in speeds through tubing is 50 feet per minute or greater. When encountering the permanent completion, before the connection is made, speed should be reduced to less than 10 feet per minute.

  • Do AccessESP systems require additional well control when RIH?

    No. However, the system can be deployed into a live well with standard lubricators and slickline equipment.

  • How do AccessESP systems mitigate the challenges during rigless deployment?

    The retrievable assemblies have been divided into four runs, designed to be deployed well below the safe working load of standard slickline. Each run is installed and retrieved individually to mitigate operational challenges.

  • Can AccessESP systems be deployed via the power cable?

    No. AccessESP systems have been designed to be light and small to permit deployment with a standard slickline unit. A typical power cable weighs 10,000 pounds, leading to a very heavy, invasive deployment system.

  • Can the retrievable assembly be deployed in less than four slickline runs?

    Yes. We can deploy and retrieve in three runs, if required. However, we recommend deploying in four runs to mitigate operational challenges.

  • What is the minimum length of the retrievable assembly tool runs?

    The first two slickline runs average approximately 40 feet each. The last two runs average 5 feet each.

  • Can AccessESP systems be deployed into a live well?

    Yes. We can deploy and retrieve with a lubricator. Deployment typically requires a 60-65 foot lubricator.

  • Are AccessESP systems compatible with industry standard gas handling equipment?

    Yes. Our solution is compatible with industry standard gas handling equipment.

  • What is the gas separation route?

    We have incorporated a gas vent sub that provides gas migration to the annulus, if necessary.

  • Can you retrieve just the pump if needed?

    Yes. In the instance that pump replacement is the only operation that needs to be performed, it can be removed and replaced without retrieving the entire assembly.

  • What is the weight of the slickline retrievable assembly?

    In a typical application, the first two slickline runs average 1,000 pounds each, the second two average 100 pounds each. The weight is dependent on the pump design, the system size, and the power rating.

  • Can AccessESP systems be run through doglegs of 10°/100 feet?

    Yes. We have qualified our system to be installed in doglegs up to 12°/100 feet. We have tested and successfully installed systems in doglegs of up to 18°/100 feet.

  • Can AccessESP systems be deployed in horizontal and highly deviated wells?

    Our systems have been installed from vertical (0⁰) to horizontal (90⁰). In deviations over 60-65⁰, deployment is typically performed with a tractor or coiled tubing.

  • How many crew members are required to install the AccessESP system?

    For installation of the permanent completion a two to four person crew is required, depending on daylight or 24-hour operations. For deployment of the retrievable assembly, a one to two person crew is required.

  • Can remediation or intervention tools be run through the permanent completion?

    Yes. AccessESP systems are compatible with all intervention and remediation operations.

  • How do you know when the system is connected?

    After connection of the wet connect system, the electrical circuit is made and the motor resistance can be measured and the ESP gauge data can be read, at surface.

  • What is the length of the lubricator?

    Lubricator length depends primarily on the length of the pump being used. Typical lubricator lengths are 60-65 feet.

  • Why doesn’t AccessESP provide an option for tandem/triple permanent magnet motors (PMM)?

    The permanent magnet motor used in AccessESP systems is capable of delivering the power required, in virtually any well, in one section. This has allowed us to design a much simpler motor that eliminates the complications and operational risks of a tandem/triple motor deployment.
