HISTORICAL DOCUMENT. This NACE standard is a guide for selecting corrosion resistant materials for the supply, storage, pumping, and injection of water encountered in oilfield operations where external or subsea exposure to saltwater is not a consideration. These recommendations are also applicable to metals used in conjunction with carbon dioxide injection. Special metallic materials are required for many water handling systems; however, a thorough evaluation of the water in each operation should be conducted to determine if such materials are required. Nonmetals are not covered in this standard, but where nonmetals are a solution, they are listed as such for the specific effectiveness they may provide. This standard considers only the corrosion aspects of material selection.

This standard has been prepared by NACE Task Group T-1F-7, which is a component of NACE Unit Committee T-1F on Metallurgy of Oilfield Equipment. T-1F functions under the auspices of Group Committee T-1 on Corrosion Control in Petroleum Production. The T-1F Unit Committee is composed of individuals representing manufacturers, suppliers, and users of oilfield equipment. The materials and metal property requirements given in this standard are based upon a review of field data and represent the best judgment of Task Group T-1F-7 and T-1F. Each system should be evaluated to determine the applicability of the stated material.

1.1 This standard has been prepared as a guide to the selection of corrosion resistant metallic materials to be used in all phases of handling water for injection into oil-bearing formations. Included in the application of this standard are metallic materials used in conjunction with carbon dioxide (CO2) injection.

1.2 The materials tabulated are only those frequently used for the purposes shown in the tables and are not implied to be the only materials suitable for the stated purposes.

1.3 This standard is not intended to provide complete material specifications for design purposes.
