Columbia Gas preserves wetlands with directional drilling. K.K. Luginbuhl and D.K. Gartman. Pipeline Gas J., October 1995, 222(10), 61--65.
Alleviation of pressure problems by installing 9500 ft of a 12 in. pipeline loop is described. Wetland areas are characterized as hydric soils, hydrophotic vegetation, and hydrology. A directional drilling technique is used to install the pipeline loop with minimum disturbance to the environment while preserving access for customer services. The pipeline is divided into six drilling/boring segments with stage and pull-back areas located outside the wetlands. Coping with problems caused by drilling mud blowout is discussed. A vacuum tank truck is used for cleanup operations. The analysis of core drillings is discussed. Six guidelines are recommended for pipe installation projects in wetlands areas.
