A simple tool to assess the cost-effectiveness of new bit technology

Bomber, T.M.; Pierce, K.G.; Livesay, B.J. - 2010

Cost or performance targets for new bit technologies can be established with the aid of a drilling cost model. In this paper the authors make simplifying assumptions in a detailed drilling cost model that reduce the comparison of two technologies to a linear function of relative cost and...
