• GLift started in 2016, 100 % Canadian private entity, locally owned • Service includes Gas Lift, GAPL (gas assisted plunger lift) and conventional plunger lift evaluation - design, supply, installation, optimization and maintenance servicing for all applications • Providing premium gas lift services in Western Canada • Canada’s only mobile gas lift service unit to ensure valve setting accuracy and installation success • GLift is unique and flexible to ensure project success with expertise and dedication from project scope to production optimization
Why Gas Lift? HZ drilled multi-well pads, gas lift is best option A/L applications in the Montney and Duvernay are ideal Avoid Rod Pumping Issues due to high wellbore deviation: Over capitalization, rod buckling and extreme tubing wear Other Rod Pump Challenges: gas interference, debris handling, casing wear due to unanchored tubing
GLift Provides Free Gas Lift Evaluation, Design and Flow Modeling
Recent Project Activity NW AB Montney Well with Gas Lift Deployment – GLift Optimized (Decline Reversed) CGR = 158, WGR = 77 (bbl/mmcf) Start of Gas Lift Q inj = 425 mcfd Critical Lift Rate = 750 mcfd
Recent Project Activity NW AB Montney Well with Gas Lift Deployment – GLift Optimized (Decline Reversed) CGR = 52, WGR = 136 (bbl/mmcf) Start of Gas Lift Critical Lift Rate = 1250 mcfd
Recent Project Activity NW AB Montney Well with Gas Lift Deployment – GLift Optimized (Decline Reversed) CGR = 41, WGR = 171 (bbl/mmcf) Start of Gas Lift Critical Lift Rate = 750 mcfd
Gas Lift Installed on Initial Completion NW AB Montney Well Decline – Low Producer / High WC Gas Lift Application Natural Flow, lasted 5 months prior to unstable flow Gas Lift Optimized, LGR 200 bbl/mmcf, 70 % WC 10 year Forecast, LGR 200 bbl/mmcf, 70 % WC Initial Gas Lift Start-Up, LGR 350 bbl/mmcf, 50 % WC *Gas Lift installed on initial completion best recommended practice, gas lift can keep well flowing with reservoir pressure support
Gas Lift Not Installed NW AB Montney Well Decline – High Initial Producer – Requires Gas Lift LGR 115 bbl/mmcf, 0 % WC LGR 275 bbl/mmcf, 50 % WC *A/L installed later in well’s life requires expensive workover, gas lift on initial completion is more effective, can be started on demand
