PulseEight

PulseEight Overview

Our Wireless Intelligent Completion platform is called PulseEight; within this, we have three distinct tools. All three tools have a similar design and appearance and all tools are retrofitted into your existing completion, typically deployed via slickline but E-Line, Coil Tubing could also be used. All of the tools use batteries as their source of power; the longevity of the batteries depends on how often the tool is used and the setting depth temperature. Each tool can be evaluated on its longevity after the enquiry form is completed.

PulseEight Secure

If you are facing an issue with your tubing deployed Safety Valve operation, the Secure can be used as a replacement and supply more functionality than the existing valve. The PulseEight Secure is fully qualified to API 14A V2, and our facility is API Q1 Certified. Like all PulseEight tools, these are typically retrofitted into your existing completion design and deployed via slickline, and landed and secured by several methods (Retrievable Packer, Lock/Seal). Once Secure is deployed and functioning, it has the ability to automatically close on Emergency Shut-Down, Loss of Containment and Absolute Pressure. These triggers are fully customisable prior to deployment. The Secure will also send, typically at midnight, a pulse to verify the health of the tool and an indication of the battery's health as time moves on. The Vitality pulse is monitored to ensure the health of the tool but also to follow the health status of the batteries. As the tool reaches the last part of its end of life of the battery, the pulses shift in time, indicating the battery life remaining and allowing the operator to plan ahead and replace the tool. If all warning signs are ignored, the tool will automatically close if it reaches a critical low level of battery.

Another great feature of the Secure is that normally, no additional topside equipment is required as we typically use the operator's existing wellhead pressure sensor.

The tool is fitted with Quartz Pressure & Temperature sensors Up/Downstream of the choke section, and all data recorded is stored within its internal memory. No data is sent to the surface since the tool is vital to the operator's Safety System.

PulseEight Control

The second tool in the platform is unique and deployed in the same way as the others, but this time, the Control is being used to focus on typically Water or Gas breakthrough from a specific zone or just to reduce overall. The Choke section of the tool can be commanded from surface to open or close to any percentage size allowing the operator full control of what amount is being produced via the tool. This tool is also fitted with Quartz Pressure & Temperature sensors Up/Downstream of the choke section, and all data recorded is stored within its internal memory, but the tool can be set to send information to the surface. The tool can send the following data, Pressure, Temperature and one other extended piece of information from the following (Differential Pressure, Shut-In Pressure, Choke Position, Battery Voltage and On Tool Memory Storage). This data can be sent either Daily, Every second day, Weekly or Monthly and this frequency can be selected while the tool is deployed in position.

The tool can also detect when the well has been shut in and will automatically move to a fast scan rate and record all data to its memory until the well is opened again. Once the tool sends its first P/T ready it will also supply the Highest Shut-In Pressure that has been recorded during the shut-in period. Note that all of the higher scan rate data is not sent to the surface and is, at the moment, stored in its internal memory.

Typically, additional equipment is required at the surface to decode the pressure pulses.  The PulseEight Control can be used for the following as well, Interval Control, Multi-Lateral Control, Autonomous Gas Lift and Cross Flow Prevention.

 PulseEight Monitor

Our third and final tool is designed to be used where either a Permanent Downhole Gauge System has failed or a system was never deployed previously.

The tool is again deployed similarly to the others, and the tool is also fitted with Quartz Pressure & Temperature sensors Up/Downstream of the choke section, all data recorded is stored within its internal memory, but the tool can be set to send information to the surface. The tool can send the following data, Pressure, Temperature and one other extended piece of information from the following (Differential Pressure, Shut-In Pressure, Choke Position, Battery Voltage and On Tool Memory Storage) This data can be sent either Daily, Every second day, Weekly or Monthly and this frequency can be selected while the tool is deployed in position.

The tool can also detect when the well has been shut-in and will automatically move to a fast scan rate and record all data to its memory until the well is opened again. Once the tool sends its first P/T ready it will also supply the Highest Shut-In Pressure that has been recorded during the shut-in period. Note that all of the higher scan rate data is not sent to the surface and is currently stored in its internal memory. Typically, additional equipment is required at the surface to decode the pressure pulses.
