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

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

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

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