Evaluation of the Corrosivity of HDD Drilling Fluids Utilized for Ductile Iron Pipe Installations
Publication: Pipelines 2007: Advances and Experiences with Trenchless Pipeline Projects
Abstract
Many HHD installations utilize specialized drilling fluids, commonly called "drilling muds", which are composed of various organic and inorganic additives, polymers, lubricants, and wetting agents mixed with water. One common component in drill fluids which can be corrosive to metallic structures in certain environments is bentonite clay. This one year study investigates the corrosive effects of various commercial drilling fluids on Ductile Iron Pipe utilizing two widely recognized ASTM corrosion evaluation methods: ASTM G-59 (Standard Test Method for Conducting Potentiodynamic Polarization Resistance Measurements) based on electrochemical properties of metals, and ASTM G-162 (Standard Practice for Evaluating Laboratory Corrosion Tests in Soils) based on coupon weight loss. In addition to comparing the corrosive effects of various drill fluids, five different electrochemical test evaluation methods were compared to results obtained utilizing the weight loss method.
