This type of unconventional production differs from historical conventional approaches, with far reaching consequences for asset integrity management. The present paper outlines corrosion threats associated with shale development, including acidizing, fracing, flowback, CO2 and H2S in produced fluids and artificial lift. Usually little detailed information about corrosive exposure is available upfront. The production mode contributes to complex and highly variable environmental conditions. Corrosion cracking and weight loss corrosion of well completion materials are known to have occurred. Whereas classical asset integrity management is usually rolled out over many years, the typical timescale in shale production ranges from just months to a few years, driving low-cost, quick earn-back scenarios. This paper discussed the consequences for materials selection and corrosion control. Keywords: Shale, unconventional, fracing, corrosion control, integrity management, material selection INTRODUCTION The United States has abundant natural gas resources that play a major role supplying energy to homes and businesses. Data for 2017 collected by the U.S. Energy Information Administration (EIA) showed that petroleum and natural gas supplies approximately 66% of the nation’s energy, with natural gas alone delivering about 26%. 1 Shale gas resources extend across the lower 48 1 Paper No. 13189 ©2019 by NACE International.
