Drilling fluid and cementing improvements reduced per-ft drilling costs by 10% ///

Comparing the drilling program in White River Dome field, Colorado, of 2001, in which 26 wells were drilled, with the 2002 program, in which 14 wells were drilled, shows that coordinated well design significantly improves drilling performance. Lessened wellbore washout, improved cementing practices and increased bit performance reduced costs from $77.54 per ft in 2001 to $69.56 per ft in 2002, resulting in a savings of $810,000 for the 2002 drilling program.
