General information

Well and rig summary information plus the date that the well was spudded and abandoned / suspended / handed over to Production.

Well schematic showing final well status.

Time vs Depth graph, showing planned vs actual performance.

Final cost breakdown showing planned vs actual costs by category.

A summary of good points from drilling the well.

A summary of areas of concern or problems encountered while drilling the well.

Drilling Operations

Description by hole section (text); use the Drilling Supervisor’s Daily Diary notes as the basis along with daily drilling reports etc.  Write out a description of events.  Note especially information on how best to drill each formation encountered; include suggested bits, parameters, mud properties, drilling practices etc.

Bit performance analysis; planned vs actual performance, constraints on bit performance, notes on how the bit & BHA selection and parameters could be improved.

Mud performance analysis.  Show planned vs actual performance, problems encountered (especially borehole stability related), how these problems were handled, suggestions for improvements on the next well.

Casing and cementing performance analysis.  Discuss problems encountered, comment also where performance was good.

Specific problem areas; fishing jobs, other remedial work, kicks etc.

Other items not covered by the above areas.

Conclusions and Recommendations.  How time could be saved, problems avoided or reduced, anything to improve performance next time.

Rig; Personnel, Equipment, Procedures and Contract

Factors affecting drilling performance (related to personnel, equipment, drilling programme, procedures or rig contract).

Solids control equipment performance analysis.

Conclusions and Recommendations.

Logistics

Equipment lists as shown in the Drilling Programme; show any deficiencies in these lists.  (i.e. update for future reference)

Highlight any problems regarding vessels, helicopters, road transport etc.
