12 Ultra-Short Radius Multi Laterals High permeability channels placed using high pressure fluids and steel tubing.

13 Ultra-Short Radius Multi Laterals High pressure fluid is changed to high velocity fluid jet as it exits the nozzle and cuts the bitumen.

14 Ultra-Short Radius Multi Laterals High pressure on the inside of the nozzle hydraulically injects the steel tubing into the formation. Fluids and cuttings are returned to the main wellbore through the lateral.

15 Ultra-Short Radius Multi Laterals Placed anywhere along either the injector or producer, as required.

16 Ultra-Short Radius Multi Laterals Placed radially in any orientation and can reach as far as 100 meters into the formation.

17 Ultra-Short Radius Multi Laterals Devon Q Placed in a new injector 14 laterals placed Laterals were not lined On production

18 Ultra-Short Radius Multi Laterals

19 Ultra-Short Radius Multi Laterals Devon Slim Hole Pilot While drilling the producers Devon identified a low permeability layer directly above the injector in two of their wells In 7 weeks PetroJet and Devon developed a new process and PetroJet was on site. Project morphed from a reservoir project to a proof of concept project.

20 Ultra-Short Radius Multi Laterals Devon Slim Hole Pilot Went into the injector after drilling but before it was lined. Placed 14 vertical laterals, 12 x 7.2 m and 2 x 3.5 m. Lateral locations were placed at strategic locations along the wellbore. Liner was successfully installed

21 Ultra-Short Radius Multi Laterals Proof of Concept Results Using the PetroJet System, ultra short radius laterals can be placed in a horizontal bitumen well Hole integrity can be maintained throughout the project A liner can be placed into the main wellbore after laterals have been placed

22 Ultra-Short Radius Multi Laterals Cumm to July 2014 FF1 FF2 FF3 Injection Oil Water Fluid Most production is now coming from between the injector and the producer Time to conformance is increased when there is vertical permeability present

23 Ultra-Short Radius Multi Laterals Time to conformance is increased when there is vertical permeability present

24 Ultra-Short Radius Multi Laterals Vs Fishbones Fishbones Drilling Operation Pre-planned Random 100 m radius Hole Dia is bit size More Wellbore or Ghost Holes Multi Laterals Completion Operation As required Pinpointed by logs 3, 7 or 11 m radius Hole Dia is variable Orientated High Permeability Channels

25 Multi-Lateral Simulations SPE MS-P Numerical Simulation of SAGD with Vertical Slimholes - Chang, Ivory, Tunney (Alberta Innovates) In reservoirs with shale barriers the slimholes significantly improved oil recovery at 2764 days from 49.3 to 75.2%... (52% increase) Use of vertical slimholes is an effective technology for SAGD applications in reservoirs with a continuous shale layer. They improve SAGD performance by recovering oil from previously inaccessible oil from above the shale layer where a secondary steam chamber is formed.
