Category Description

Plunger Lift is one of the artificial lift methods that use well's natural energy to lift the fluids. It is mainly used to de-liquefy (water, oil, wax etc) in a natural gas well.  The underlying principle of the Plunger Lift is a plunger/piston inside the production tubing that travels up and down. It uses reservoir pressure build-up and rise and gravity forces, to come back to the bottom. This is achieved by shut-in and flow periods that open / close the shutoff valve down-hole with the predetermined time intervals.  The system is entirely mechanical.

Modern days, multistage plunger lift equipment may take the technology to a higher operating envelope. The Plunger Lift method is widely used to produce fluids in the fields that have a significant amount of natural gas. Application of the Plunger Lift is limited to less than 5,000 B/D productions.

Plunger Lift system consists of:

  • Down-hole assembly 
  • Control section, lubrication at the surface
  • Surface arrival sensors 
  • Flow chokes 
  • Solar panels

Supply & Demand Dynamics Image

Supply & Demand Dynamics

More than 70-80% of wells worldwide use the artificial lift. Depletion rate and maturing of the oilfield is the major driver for using artificial lift technologies.  The segment is expected to witness a growth rate of almost 10% CAGR from 2014 till 2019 (source: Markets & Markets).  North America holds almost half of the market and will continue to be dominant. A number of artificial lift suppliers are actively expanding their presence globally with more R&D hubs manufacturing plant and services centers. 

Globally, Plunger Lift systems represent around 5 % of the population, but circa 10 % in non-rod pumping. The biggest market of Plunger Lift systems in China and Canada. 

Currently, GCC represents the smallest market for Plunger Lift.

Cost & Price Analysis

Price Analysis
Plunger Lift systems represent a very low market share globally.  Prices for Plunger Lift systems have always been driven by supply and demand. In the long run, prices will not exhibit any volatility and will be driven by commodity prices. 

 

Cost Analysis

Plunger Lift systems mainly consist of mechanical parts, steel components, and some electrical parts. Hence, commodity prices and capacity utilization of manufacturers drive the costs of plunger lift systems
