Pilot Energy Patents

  • NGL recovery from LNG – Cold side
  • CO2 fractionation for capacity increases
  • HIREX – Extremely High C3+ Recovery with Low

Vapor Pressure (Low C2 Recovery)

  • NGL recovery from CO2 by Fractionation I and II

Primary Production

Oil + Gas + NGLs

Secondary Production

Oil + Gas + NGLs

Tertiary Production

Oil Only?? No Gas, No NGLs?

Why NGL Recovery

  • Can add 25% to field production
  • Increases recoverable reserves
  • Additional revenue stream
  • Increases CO2% in recycle (good/bad)
  • Sequester more CO2
  • Provides dehydration of recycle stream

Processing Options

  • Ryan Holmes – most expensive
  • Membrane/Amine – close to most expensive
  • Bulk Fractionation (Pilot)– way less expensive
  • Refrigeration – least expensive
  • All are more expensive than

conventional gas processing

Why is this so hard??

A simple analogy

  • Methane = Baby Powder
  • CO2 = Sugar
  • Ethane = Salt
  • Propane = BB’s
  • Butane = Marbles
  • Pentane = Golf Balls
  • Crude = Basket Balls

Basis for Comparison

Case Study

  • Flow Rate = 20 MMSCFD
  • Interstage Pressure = 550 PSI
  • H2S + N2 = 2.9%
  • CO2 = 88%
  • C1 = 2.8%
  • C2 = 1.9%
  • C3 = 2.0%
  • C4 = 1.4%
  • C5+ = 1.0%

Just Because You Can, Doesn’t Mean You Should

  • Methane content worth $600K/Yr, Most/all

is consumed to extract. Payout = ∞

  • Ethane: Worth more, but hard to market –

Unless you have access to an NGL pipeline, you can’t keep it.

Pilot Commercial

  • Pilot will build, own, (operate), pay 100% of the cost,

give Producer a share of $$ for no cost

  • Or
  • If the stream is too lean, Pilot will J.V.
  • Or
  • If the stream is really rich, Pilot will process for a fixed

fee and give Producer all production

  • Or ???
