2.1.1
Preliminary Work For the Drilling Program [ ]

Sidewall sampling, formation sampling (RFT/MDT), and coring
requirements
Cement logs
Reporting requirements (daily and post-well)

Mud logging:

Sampling and preservation methods required for cuttings, cavings,
mud, produced fluids, metal, etc.
Recording requirements and formats
Type of unit (e.g., off or online)
Monitoring services required, types of alarms/alerts, routine calcu-
lations (e.g., monitor current kick tolerance, D exponent, etc.)
Reporting requirements (daily and post-well)

Well completion/testing:

Normally, detailed completion/testing programs will be sent out
closer to the time. General notes should be made to allow some prepa-
ration to take place.

Precompletion requirements anticipated (e.g., bit/scraper runs,
gravel packs, fracs, screens, packer setting, and completion fluid
specifications)
Tubing sizes and surface wellhead configuration
General list of types of downhole completion/testing tools to be
run with the completion tubing (e.g., side pocket mandrels, safety
valves, packers, downhole sand screens)
Reporting requirements (daily and post-well)

Well suspension/abandonment:

Anticipated well configuration on rig departure (diagram useful)
Zonal isolations required
Whether casing will be cut and pulled
Cement plugs and permanent bridge plugs depths, etc.
Whether suspension caps will be required
Refer to government and company regulations or policies concern-
ing abandonment
Reporting requirements (daily and post-well)
