Selection of Land drilling rig should be based on planed depth and well construction in the long term drilling Selection of Land drilling rig should be based on planed depth and well construction in the long term drilling activities. activities.

More important is to decide area of activity.More important is to decide area of activity.

Nort Africa, Middle east and partlly Caspian regionNort Africa, Middle east and partlly Caspian region: Majority of drilling contracts (activities) are : Majority of drilling contracts (activities) are related with related with

drilling wells depth range 3000 to 4500m (dominantlly deeper then 3900m).drilling wells depth range 3000 to 4500m (dominantlly deeper then 3900m).

Caspian region:Caspian region: Still have great activities at depth range up to 3600m.

This fact determine drilling rig type selection. If rig is planed to work depth range up to 3600m then is prefferable to

select mobile, telescopic drilling rig rated up to 1000 HP.

Drilling rig name is dictated bu name of Drawworks.

Rig depth rating is determined by:Rig depth rating is determined by:

1.1. Draworks capacityDraworks capacity

2.2. Mast capacityMast capacity

3.3. Crown block and travelling block capacityCrown block and travelling block capacity

4.4. Drilling line size and pulling forceDrilling line size and pulling force

Advantage:Advantage:Stands in the tripple – faster tripping Porefull equipment – drawwork over 1000 HP, mud pumps over 1000 HPUses 5” DP – at greater depth less pressure losses.Havy casing string run deeper –Hook loads over 200 tDiesel electric drive.Flexible range of RPM and SPMSubstructure higher and drilling floor greater area.DP length upper limit for rangeBetter Contractor’s References.Disadvantage: Greater investmens at startMore days for movingMore truck loadsLonger rigging upLarge surface of well siteMore personnel –more experienced and specialistHavy drilling and handling equipmentMore investment for spare part stock

Advantage:Advantage: Smaller investment at startSmaller investment at start Faster movingLess truck loadsLess area for well siteSmaller waste pitLess number of drilling crewLess sparet parts stock

Disadvantage: Stands in the double- slow triping When drill deeper with 4 ½” DP or less, greater pressure drops. Restricted running depth of intermediate casing if well construction is complex due overpressure and lost circulation zones. Mostly mechanical rigs – high noise level. Mud pump SPM restricted due drive diesel engine. Required 3 liner sizeRestricted height bellow rotary table for BOP stackLess surface of drilling floor – safety DP length restricted on bottom length limit.
