Much of the known oil and natural gas reserves in North America have fallen into the mature category. All world wide oil and natural gas fields will eventually also fall into this category. Many of these marginal oil and natural gas fields are under producing or even dormant due to inefficient and costly methods of fluid recovery.

Natural Lift Systems (NLS) has developed a revolutionary method of capturing downhole pressure to unload oil or unwanted water in gas wells (bottom hole pressure required is minimal). Our proprietary casing plunger design uses hydrostatic pressure to power the tool. If your well makes fluid, this tool will cycle! Imagine zero lifting cost, no complicated timer devices at surface, no tubing changes and the increase in production when your well produces in casing. The application for a cost effective tool with advanced technology to work in marginally producing wells is vast.

Let NLS unload your wellbore fluids, using your own wellbore pressure and greatly increase your production!

ARTIFICIAL GAS LIFT TECHNOLOGY

Much of the known oil and natural gas reserves in North America have fallen into the mature category.  All oil and natural gas fields worldwide will eventually fall into this category also.  Many of these marginal oil and natural gas fields are under-producing or even dormant due to inefficient and/or costly methods of fluid recovery.

Natural Lift Systems (NLS) provides solutions to enhance or sustain your gas wells. Plunger lift is a typical method for optimizing gas wells. Our equipment will unload liquids in your well, increasing your production. Plunger lift is also economical because it utilizes the well bore pressure as an energy source, whereas other forms of artificial lift require expensive power requirements.

NLS Tubing Plunger Systems

·2 3/8” (60.3mm) and 2 7/8” (73mm)

3 1/2” (88.9mm) and 4” (101.6mm)

  • Solid Ring, Single Pad, Dual Pad, Brush and Natural Flow Plungers are available
  • Custom solutions, Research and Development shop.
  • Internal or External Fishneck configurations

·Full Service Solutions are provided from local machining to installation and maintenance by strategically located technicians.

  

NLS Tubing Plunger Lubricator

·The NLS Lubricator out-performs all competitors with a 5000 psi integral body and internals that surpass any current specifications. No welded components provide greater safety for service and company personnel. Threaded ports are integral for increased safety. The springs are either Inconel or Stainless Steel, for sour or sweet applications. Installation is simple compared to other types of plunger equipment.

           

NLS Bottom Hole Spring Assemblies

·The NLS Ti bottom hole spring assembly incorporates a Titanium fishneck and Inconel spring, which is used in sour applications, greatly increasing the life of the fishneck and plunger. For sweet applications, L-80 material is used. Each system can accommodate a check-ball and be set in the tubing string with various seating assemblies. 

 



Natural Lift Systems uses the AliEn Controller, the ALiEn is a versatile, low power controller for gas well applications that is built to endure harsh weather conditions. Designed as a low cost production enhancement tool, the ALiEn makes plunger lift configuration simple with its intuitive menu based interface and easy to read display.

Standard Features

  • Approved for mounting at wellhead in gas environments
    • Meets CEC 79-11
    • Intrinsically safe Ex ia IIB
    • Class 1, Division 1, Groups C & D
  • Operates effectively from -40°C to 85°C/li>
  • Rechargeable 6V battery can provide over 21 days of normal operation at -40°C without external power
  • Designed to operate with an Extreme Telematics Solar Panel that allows the controller to run indefinitely
  • Mounting space for up to 4 valves
  • RS-485 serial port that supports Modbus
  • Conformal coating protects controller from corrosion
  • Easy to use menu based interface with arrow and select/cancel keys

ALiEn Versatility

The ALiEn can be upgraded to make plunger lift control even easier with its powerful self optimizing feature that uses pressure and flow rate to maximize the potential of your well.

When installed with a minimum 2 of the following 4 inputs, our controller will have enough information to run its self-optimizing routines.

  • Line Pressure Switch Input
  • Differential/Pressure Switch Input
  • Casing Pressure Switch Input
  • Flow Rate Sensor Input

Additionally, the ALiEn can maintain multiple valve configurations:

  • Top/Tank valve support (Valve B)
  • Casing Valve for tubing casing flow (no annular flow control)

Casing Plunger Systems

·Reduce completion costs as no conventional tubing is required.

·Replace Coiled Tubing/ Siphon Strings if critical velocity is too low.

·No lifting costs.

·NLS patented Automatic Casing Plunger – is a revolutionary method of capturing downhole pressure to unload liquids in gas wells. The plunger is designed to sit on bottom, waiting for fluid to build-up. The hydrostatic forces trigger the plunger to close. Minimal bottom-hole pressure is then required to lift the plunger to surface. Once the plunger unloads fluid it strikes the top of your well re-setting itself, falling to bottom and repeating the process. Several types of sealing cups are available to combat most well conditions.

·NLS patented Mechanical Casing Plunger – is available where customers want to control the plunger at surface. This type of plunger will perform similar to tubing plunger installations.
