Setting the Scene Typical Time Depth Chart for a Well

Setting the Scene Some Common Definitions

The following terms will be used throughout the slides:

Weight to Weight Time: starts when the DS is lifted off-bottom & lasts until the string is on-bottom again

Weight to Slips Time: starts when the DS is lifted off-bottom until string is set in slips again

Slips to Weight Time: represents the time when the slips are removed until the DS is on bottom again

Slip to Slip Connection Time: represents the time in slips, specifically during drilling connections

Total Non-Drilling Time Per Stand: represents any time spent while drilling a stand when the DS is lifted

off-bottom, which includes all wellbore conditioning time & the Weight to Weight time.

Reaming: when pumps are on, there is rotation & block is moving up & down

Washing: when pumps are on, there is no rotation & block is moving up & down

Circulating: when pumps are on, but there is no block movement

Rig Performance Reporting Realizing Improvements & Optimizing Costs

Initial efficiency improvements were measured once the data was made available at the rig-site

and safe targets were established and communicated.

Rig Performance Reporting

Daily reporting allows rig-site personnel and management to analyze crew performance

and identify lessons learned and facilitate knowledge sharing between crews, rigs and business units.

Identifying Best-Safe-Practices

Discovered discrepancies in operational performance

revealed the need for standardization of routine activities.

Identifying Best-Safe-Practices

Changes to the directional surveying methods were implemented

to streamline the process of making connections.

Identifying Best-Safe-Practices

Results showed a reduction in off-bottom time while drilling and therefore an increased realized ROP.

Pad 2: Total Non-drilling Time per Stand, Avg (min)

Pad 1: Total Non-drilling Time per Stand, Avg (min)

Company Performance and Savings

New processes led to a significant reduction in time spent making drilling connections,

resulting in 5.78 days in savings on a 9-well pad.

Company Performance and Savings

Benchmarking performance from a previously drilled pad showed a 45-percent reduction in time

lost to off-bottom activities per stand drilled – an actual savings or more than 11 days.

Conclusion

Through a knowledge-sharing and information-gathering culture,

new processes were implemented and standardized

with an end result of significant company savings.

By sharing accountability to

increase performance through

a safety-driven culture,

routine operations become

more consistent

and rig efficiencies climb.

Company Savings continues to grow

as lessons-learned are shared

between BUs, rigs and crews.
