  • Haynesville drilling challenges addressed through MPD

    Cecil Colwell, Jim Crenshaw and Bill Bland

    While the Haynesville shale play offers great potential, it also poses significant challenges. The play is characterized by a network of fractures and faults, as well as very low permeability and high porosity that often result in over-pressurized zones. With depths ranging from 10,000 ft to 14,000 ft, the play also features significant high-pressure, high-temperature (HPHT) conditions that pose obstacles to drilling. The high cost of drilling and completing wells in the Haynesville shale presents a particularly difficult challenge to total well economics. Marginal gas prices, drilling hazards, related non-productive time (NPT), and varying initial production rates and decline rates further challenge the economics faced by operators working in the region.
