Richard Grohn, P Tech (Eng), President 28 + years in Production and Production Engineering, specializing in artificial lift and well optimization Canada and International Experience

• 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:

Other Rod Pump Challenges: gas interference, debris handling, casing wear due to unanchored tubing

Over capitalization, rod buckling and extreme tubing wear

Recent Project Activity

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

*Gas Lift installed on initial completion best recommended practice to reduce installation costs and flow interruptions

Intermittent gas lift to optimize inflow

NW AB Montney Well Decline – High Initial Producer – Requires Gas Lift

LGR 115 bbl/mmcf, 0 % WC

LGR 275 bbl/mmcf, 50 % WC

Gas Lift Not Installed

*A/L installed later in well’s life requires expensive workover, gas lift on initial completion is more effective, can be started on demand
