  1. Gas Gathering • Two typical types of compression. • Gas Driven: Can be set as Permanent, or Temporary • Electric Driven: Normally a Permanent Installation

  2. Gas Gathering Temporary Gas Compression

  3. Gas Gathering Temporary Gas Driven Compression

  4. Gas Gathering Permanent Indoor Gas Compression • Rig Counts: • North Parachute - 10 Rigs • Eureka - 2 Rigs

  5. Gas Gathering • Compressor Gas Cooler Fans (Air Exchangers) • Air exchanger fan blades are one of the biggest source of noise from the fan tip speeds. • EnCana is looking at having bigger exchanger boxes installed on new applications, to be able to slow the fan tip speeds down • One new innovation is the new “Whisper Tip” fan blades. These new fan blades cut the sound level in half.

  6. Gas Gathering Permanent Indoor Gas Compression Different Types of Coolers – Vertical and Horizontal

  7. Gas Gathering Permanent Gas Compression Horizontal Coolers with Extensions to Mitigate Sound

  8. Gas Gathering Permanent Gas Compression 3 Horizontal Coolers with Extensions to Mitigate Sound

  9. Gas Gathering • Electric Compression • Electric driven compression has no exhaust, but requires cooling of the gas with horizontal air fan exchanger. • Limitations are power supply requirements and installation costs

  10. Gas Gathering 7500 Hp Electric Compression

  11. Gas Gathering 1500 Hp Electric Refrigeration Compression

  12. Gas Gathering • EnCana uses two different muffler manufacturers. • Power Therm---The Power Therm’s are a “Critical Grade” muffler, which is a reduction of 29-35 Dba. • Miratech---The Miratech’s are listed as a “Hospital Grade”, which is a reduction of 30-35 Dba. • Muffler stacks are normally cut on a bevel to direct sound to the most desirable direction.

  13. Gas Gathering Typical Muffler Design. Most have a Catalyst section for emission control, and can either lay horizontal, or stand vertical

  14. Gas Gathering • What is Encana doing to reduce compressor noise • EnCana is currently exploring several new technologies for sound control. • EnCana is using third party sound suppression experts to help us better understand how sound travels, and the different sound frequencies
