Underbalanced = Unquestionable Value

Solving Today’s Drilling Problems

The benefits of underbalanced – increased productivity, enhanced reserves and faster drilling times are well documented. Additionally, over the life of the well, the track record of underbalanced demonstrates that long-term production and NPV can far exceed those of conventional wells in the same formation when the technique is correctly applied.

A Tale of Two Wells:

A conventional overbalanced well in Wyoming suffered fluid losses of 40,000 bbl and differential sticking, resulting in three sidetracks due to lost bottomhole assemblies. Consequently, the operation ran over budget by $6 million. Weatherford drilling and offset underbalanced well with compressors and a rotating control head in the same formation. The well lost less than 200 bbls, suffered no differential sticking and was completed under budget.
