Applications

DIAL can be applied in several gas lift production completion styles to optimize gas lift production from single and multi-zone reservoirs in onshore, offshore and subsea environments.

Single String	DIAL gas lift units strategically spaced to enable unload and life-of-well lift gas optimization. DIAL sensing units included to provide bottom-hole flowing pressure optimization reference.
Dual String	DIAL gas lift units in each production string enable complete and independent monitoring and control of both strings. DIAL sensing units between producing zones inform production management decisions.
Retrofit	Currently in the concept phase, DIAL gas lift and sensing units are installed in existing well without workover.
In-situ	DIAL gas lift units control flow of lift gas from an in-situ gas formation to the tubing string negating the need to provide lift gas from surface.

DIAL Application Advantages

At the system level, DIAL adds value on ten dimensions.

In comparison to existing gas lift technology, DIAL overcomes six primary application challenges to increase production by up to 40%, dependent on application type:

Gas Lift Challenge	DIAL Advantage
70-year-old technology, mechanically driven and sensitive to well conditions	Digitally controlled from surface, independent of well pressure and temperature
Inability to change gas injection rate or depth without well intervention	Continuous production optimization without intervention
No in-well data to assess lift gas injection depth or rate	Sensors monitoring injection depth, rate, pressure and temperature enables continuous analysis of well performance
Bellows operated valves with potential for multipoint injection and chatter induced valve failure	Surface controlled digital valves with open/close status confirmation
Industry standard IPO Valves require a pressure step down for each station along the production string reducing gas lift efficiency	Fully use available gas injection pressure allowing deeper injection for increased production
Deployment deviation limit of 60° for wireline access. Greater inclination requires expensive tractor intervention	Can be deployed at high well inclination
