30IntroductionStarted and continuously use directional drilling since 19991999 to 2004Variety of mud motors from different companies2004 to presentDeviDrill from DevicoCompleted more than metres of actual directional drilling representing 102 directional holes as of December 2006
31DeviDrill How it works (simplified version) Directional core barrel attached to drill stringRotate the core barrel in the direction you want to goCorrect for azimuth, dip or bothInflate an onboard packer to hold the core barrelin place for the change in hole pathDrill as normal within thespecifications of theDeviDrillCore is obtained using awire-line system
32DeviDrill Mule shoe system Steering the core barrel Mule shoe system used to determine the “Roll” of the core barrel. “Roll” explained as the deflection of the core barrel (0-360o) in relation to the azimuth of the holeTests (azimuth and dip) ahead of the bit can be performed at anytime while the DeviDrill is still in the hole using a survey instrument.Devico provides all surveytools and adaptablethird party toolscan be usedMule shoe system

34Operations at Shea Creek Why do we use DeviDrill?Have to look at our mud motor operations in the pastAREVA Resources with the help of Boart Longyear pioneered directional drilling in the Athabasca Basin.
35Operations at Shea Creek Why do we use DeviDrill?Less equipment and water on siteNo extra pumps, mixing tanks and rods (normally reduce one rod size smaller when using a mud motor)The DeviDrill does not require extra equipment or waterRodsMixingTanksPump
36Operations at Shea Creek Why do we use DeviDrill?No hassles with bit configurations to control the amount of water at the bit face.The DeviDrill uses a coring bit similar to normal drilling operations.EXTRA HOLESADDEDUNPLUGGEDHOLESPLUGGEDHOLES
37Operations at Shea Creek Why do we use DeviDrill?Reaming shells are not standard equipment on mud motors. Reaming directional cuts increases the cost per metre. Successful prototypes where introduced at our operations.Reaming shell is standard equipment with DeviDrill.Prototypereaming shellfor mud motor
38Operations at Shea Creek Why do we use DeviDrill?Survey ahead of the bit. To know where you are in a directional cut is crucial to positioning a hole towards a target.Any mud motor system relies on surveys (real time, multi or single shot) 9 to 12 metres behind the bit within a non-magnetic portion of the drill string. An estimate has to be made to determine the hole orientation at the bit or the motor has to be pull out of the hole and replaced by the core barrel to perform a survey.Devico provides a miniature survey tool (single or multi-shot) that can through the DeviDrill bit.
39Operations at Shea Creek Why do we use DeviDrill? (the main reason)Cost savings2006 drilling compaign, 19 directional cuts with the DeviDrill from three pilot holesAverage savings of 62% using the DeviDrill instead of re-starts from surface.Maximum savings per cut was 87%Minimum savings per cut was 50%Included in DeviDrill costs are hourly rate for drilling, rental of DeviDrill and survey equipment and all chargeable equipment including wedges, bits, drilling muds and equipment repair.

41Operations at Shea Creek How we use it?Possibly a unique situation at Shea CreekA trained designates perform all the pre-planning; decide when to put or pull the DeviDrill from the drill hole and determine the direction to steer the core barrel.The drill contractor (Boart Longyear) performs all down hole operations with the DeviDrill, schedule maintenance and repairs.
42Operations at Shea Creek How we use it?Targets are planned between 650 metres and 850 metres below surface.Distance or step-outs away from the pilot hole (vertical) varies between 20 metres and 100 metres.A wedge is placed in the hole to start the cut and directional drilling occurs thereafter.Rate of drilling is similar to normal coring. Between metre depth, 9 to 12 metres in a 12 hour shift. Time for setting the core barrel and taking tests consume time.Test taken every 3 metres, 6 metres maximum
43Operations at Shea Creek How we use it?Maximum rates of curvature performed (not recommended)1o per metre when drilling with hole direction (flattening or steeping a hole)10o per metre when drilling perpendicular to hole direction (correcting for azimuth)Dogleg 12 degree/ 30 meter )Normal rate of curvature performed at Shea Creek1o per 3 metres when drilling with hole direction10o per 3 metres when drilling perpendicular to hole directionDogleg 9 degree/ 30 meter
44Operations at Shea Creek How we use it?Rock type being drilled is Proterozoic sandstonesLaymen terms - silicified or “hard” sandstoneSeries 7 and 8 drill bits (Boart Longyear) are used for coring

48Operations at Shea Creek Issues to considerTarget objectivesWhat do you want to achieve?Is it feasible to use? Depth is not the only factor to consider.Directional drilling has a learning curveExperience is required, where do you get it?Devico or “Licensed Users” of DevicoReputable drilling contactors with experienceGeotechnical propertiesgood ground conditions are requiredfabric orientations have to be consideredBe committed and readyDirectional drilling requires input from all parties involved, “The clock is ticking when you start and money is being spent”.Maybe challenge a myth or twoRODS DO BEND!
