  • Static drilling efficiency threatens the US Gulf of Mexico


    J. Dodson, T. Dodson and V. Schmidt

    Operators and contractors that work in the Gulf of Mexico have a serious problem—static drilling performance. By monitoring drilling performance using days-drilling and rate of penetration, drilling over the last five years (2001–2005) shows no improvement in drilling efficiency. This static performance now threatens the economic life of the GOM's remaining oil and gas reserves at present exploration and production costs, even with prices at $60 for oil and $8 for gas. The rate of drilling efficiency is the aggregated result of a complex interaction of government, operating companies, contractors and supporting industries. The interacting elements include: � Technologies allowed by the Mineral Management Services' Technology Assessment Group � Operator policies of technology application � Limitations placed on drilling contractors � Limitations imposed by risk insurance on all parties � Regulations governing health, safety and environmental issues.
