24 Project Scope and Objectives Zero Emissions Well Site ProjectProject Objectives:Install a zero emissions well site configuration with a fully solar powered system and operate this system throughout the winter to evaluate performanceShare Encana’s experiences with PTAC TEREE CommitteeProject Scope: Retrofit an existing well site with a Trido zero emission solar powered system to achieve the following:Replace existing high bleed pressure and level controllers with low bleed equivalent devicesRemove existing pneumatic methanol pump and replace with solar-electric methanol pumpInstall battery packs, solar panels and electric actuator with air compressor and air receiver to supply pneumatic controls
25 Previous Configuration Zero Emissions Well Site ProjectSelected Well Site:Older deep gas well with a two phase (gas/water) separator and a plunger lift located near Three Hills, AlbertaDeliberately chose a low profile gas well to ensure operator buy-inAverage gas production of ~1.2 e3m3/day (42 mcfd)
26 Previous Configuration Zero Emissions Well Site Project3 Primary sources of vented methane emissions:High Bleed Pressure ControllerManufacturer spec estimated vent rate of 25 scfh (continuous)High Bleed Level ControllerManufacturer spec estimated vent rate of 30 scfh (continuous)Pneumatic Chemical PumpEstimated vent rate of 15 scfh average over the yearAug 2012: took field measurements of controller vents using a high flow sampler and a diaphragm meterMeasured 17 to 30 scfh from the two controller ventsChallenging to get low pressure vent gas to go through meter as FLIR camera showed gas leaking into building instead of out ventEstimated GHG Emissions of ~150 to 235 tCO2e/year for this site

37 Initial Learning Curve Operational ResultsInitial Learning CurveEquipment installed Oct 31st/ Nov 1st, 2012Freezing rain and very overcast weather right after start-up caused some issuesNovember 1, 2012 to December 3, 2012 various issues during first month of operationsWiring issue as panels were wired in series, not in parallelBatteries were not charged prior to installation, system did not deliver expected autonomy during first cloudy dayMoisture in compressor air intake froze off – re-piped air intake to be from inside buildingCompressor seals subsequently had to be replaced after methanol used to thaw frozen air intake degrading sealsFuse for the compressor burnt out and was replaced
38 Reliable performance through the winter Operational ResultsReliable performance through the winterFrom December 3rd 2012 through the rest of winter the air compressor ran smoothly with no reported shutdowns and delivered air at a steady 30 psigAugust 2013 – 2 day shutdown due to compressor valve issue caused by dust/dirt getting into the air compressorCompressor valves replaced and filter added to the air intake to prevent same issue in the futureLow system power consumption with average night time power use of ~5 wattsSolar chemical pump has not had any issues to date
39 Conclusions Conclusions Overall the system operated reliably throughout the winter and did not cause any significant downtime during cold weather, after the initial learning curve during the 1st month of operationsRecommend that additional care be taken to avoid issues with the air intake if excess moisture or dust gets into the air compressorInstallation costs could be reduced with better wiring and pre-assembly of systems in advance of arrival at lease siteEconomics are a challenge for retrofits, but costs of a zero emission well site system could be comparable for a new build well site if the comparable design requires a thermoelectric generator (TEG), fuel cell or larger solar/battery pack
