HOW WE DID IT
31
Keys To Success
• Con]nuous Drilling Program • Stability of Personnel • Focus On Key Performance Indicators (KPI’s) • Incen]ves • Create and Maintain Team Atmosphere • Constant Communica]on • Con]nuous Improvement Focus
32
CONTINUOUS DRILLING PROGRAM
• 3 Year Contract • Dependable Drilling Rigs • Working Closely With Drilling Contractor to Improve Opera]ons
• Con]nuity with Key Service Providers
33
STABILITY OF PERSONNEL
– Drilling Superintendents – Drilling Supervisors – Drilling Engineers – Drillers – Toolpushers – Direc]onal Drillers
34
FOCUS ON KPI’s
• Days per Phase (Air & Horizontal) • Cost per Phase • ROP Slide and Rotate and % • Flat Time analysis • Rig Mobiliza]on Time and Cost
35
Eliminate The Train Wrecks
• Wellbore Collisions • Stuck Pipe Leading to Side Tracks • Comple]ons Fracing In To Drilling Well • Stuck Casing • Well Control Issues • Rubble Zones • Geological/Targe]ng Side Tracks
36
INCENTIVES: 1st Iden]fy the Cri]cal Performers
• Drilling Superintendents • Drilling Supervisors • Drilling Engineers • Rig Crews – Toolpushers – Drillers
• Direc]onal Drillers • Mud Engineers
37
CREATE TEAM ATMOSPHERE
• Establish Clear Responsibili]es • Maintain Accountability • Share Success • Review Failures Without Punishment • Encourage Par]cipa]on at Every Level • Provide Individual Recogni]on When Earned • Work Closely With Service Providers in Non Adversarial Respectul Rela]onships
38
C0NSTANT COMMUNICATION • Monthly Mee]ng With Drilling Contractor • Pad Spud Mee]ngs • Daily Conference Calls With Rigs and Office • Superintendents visi]ng rig on near daily basis • Open Door Policy • No BIG ME, liJle YOU AItudes • Par]cipa]on at Every Level • Useful Drilling Programs • Consistent Approach With All Rigs • NO Micro-‐Managing From Office
39
CONTINUOUS IMPROVEMENT FOCUS
• All Brine/Polymer Systems • Low Solids Mud • Conven]onal Direc]onal Assemblies • Casing flota]on • Shorter bit to bend motors • Performance Based Bit Selec]ons
40
Future Savings Opportuni]es
• Reducing Rig Mobiliza]on Costs • Reducing Loca]on Costs • Reducing Waste Disposal Costs • Reducing Number of Casing Strings
