NESS Programmer
Read full descriptionHide full description
The NESS Programmer allows users to easily configure the NESS downhole tool in a matter of seconds using Bluetooth communication, avoiding the need to use dip switches on the tool's controller board. Avalon Research's NESS downhole tool is a Non-Explosive Setting System. This proprietary, self-contained system runs on battery power and hydraulic fluid. It is lightweight, simple, and incredibly inexpensive to operate. It requires minimal redress and can be used for multiple runs with minimal downtime. Electric power is provided by the onboard re-chargeable Ni-Cad battery pack. Run in tandem with a modified multi-stage setting tool, the NESS is unaffected by wellbore pressure. The hydraulic pump is capable of generating 15,000 psi of continuous hydraulic pressure. The pump uses a specialty heat transfer fluid to provide hydraulic pressure and does not operate on wellbore fluids to prevent contamination. The electronics are encased in an insulated thermal flask and the system is designed to withstand up to 400F for 2 hours. Primary Applications: β’ Off-shore fields requiring heli-deployed non-explosive setting tools. β’ High-risk areas where transporting explosives is prohibited, restricted, or unwise. β’ Operations where multiple well completions require several runs per day. β’ Time-sensitive jobs that canβt depend on the logistic deployment of explosives, or the availability of a blasting tech.
