Digital Drilling System
Low cost of ownership and operatorship plus vendor-neutrality makes PDS a viable digital drilling solution – and potentially an industry-changing platform - for all well programs and drilling applications
• Custom-drill pipe required: considerable manufacturing cost, restricted supply
• Extensive machining requirement: high refurb/R&M cost, considerable facilities needed
• Low torque capacity• Substantial added connection time• Low/no electrical power provision (batteries)• Complex and/or fragile electrical conduit• Required multiple repeaters decreasing
reliability• Vendor-specific• Very niche operational application
Powerline Drill String (PDS)• Can be retrofitted on existing drill pipe: can
be installed practically anywhere• Dedicated mobile unit for installation, machining,
R&M: nominal refurbishment/parts costs• No impact on pipe torque specification: multiple
sizes/connection types with same kit design• No added connection time• 300 W lossless electric power• 200,000 bps no-latency comms, no repeaters• Vendor-neutral• Low-cost plus ease-of-use: broad industry
application

Eliminate M/LWD and RSS key points of failure:• No batteries, pulsers, turbines – increased MTBF• No depth limitation due to weak transmission• Facilitates MPD/UBD application• No repeaters• All diagnostics transmitted in realtime• Powered cooling of BHA components in HT wells
Minimise/eliminate wireline• Realtime millimeter-resolution LWD imaging while drilling• All LWD curves transmitted in realtime, no memory dump• Identify and characterise fracture and borehole breakout• Wireline-equivalent LWD resolution without delay/damage
Optimise well placement and sampling• All LWD curves transmitted in realtime for optimal geosteering• No battery/pulser means measurement close to bit• Precisely position, and power, optimal pressure/fluid sample points• Reduce costs by eliminating unnecessary/unsuccessful samples
At-bit and Along String Measurement• Realtime holistic visibility of drilling and hole conditions along wellbore• ‘See’ solids loading/cuttings beds, differential sticking, DLS, influx/loss• ‘See’ vibration, friction, bending/buckling, drillpipe/casing wear• ‘See’ WOB/torque transfer, optimal neutral point, bit performance• ‘See’ immediate effects of preventative and remedial actions
Directional drilling• Instantaneous surveys, instantaneous RSS downlinking• Immediate motor alignment with constant toolface updates
Optimise drilling fluid rheology• ‘See’ solids carrying and hole-cleaning along wellbore• Safely drill narrow PP/FG windows• Pinpoint influx/loss, mudcake/skin buildup• Allow use of LCM
Enable next-step in automation and real-time engineering• All required input parameters delivered continuously• Empowers full and immediate information feedback• Power electro-mechanically activated downhole tools• Control with confidence
Economically viable• Use of retrofitted drillpipe radically improves economics• Cost-effective for mainstream application• No longer just niche, high-risk/high-AFE wells• Deployabilty at scale, drives ‘new normal’ in well construction
